I found this video extremely helpful after having my serology test results. I was able to benchmark that with the Belgium study and reaffirmed my decision to proceed with a booster shot. Thanks for simplifying the Covid test results and making it easy to understand,
🤣Thats, because they had no damned idea, it wouldn't last long enough to be of any benefit, it's a 'Woopsy Moment' apparently Israel is using a 3rd dose.
Its amazing that you have answered so many comments here, you are truly a person that takes his work seriously ^^ Note : i got the Moderna version and i have never heard or met anyone that has gotten covid, i live in sweden.
Hi Eddie - thank you. Yes, this is very important to me. I think there is so much misinformation and misunderstanding out there. We all need to do our part to help with this situation. I am happy to hear about your experience. Best wishes to you and family. Stay safe.
@@NaveenAgarwalPhD hello Dr Argawal, I took monoclonal antibodies July 26, they told me to wait 90 days, before taking the covid vaccine, I was wondering if I can take my vaccine tomorrow, which is 2 days short of my 90 days, Thank You
@@zachsiatrevor Hi - in that case, I don't see any harm in taking the vaccine on day 88! Generally, the antibody levels are expected to drop after about 50 days or so. I think you were advised to wait this long to make sure the monoclonal antibody level was not compromised by the antibodies created stimulated by a vaccine. But you should do a final check with your doctor. Stay safe and best wishes.
I have had two moderna vaccines and had minimal adverse effects. I have read would be best to aspirate before injecting vaccine to make sure no blood vessel was entered to minimize relatively rare heart/coagulation adverse effects. Most vaccine centers do not aspirate and wonder if more studies coming. The few studies were from Europe and hope more standardized procedures are put in place. Thank you for posting this informative video!
Hi - very interesting and thank you for sharing this info. I would be interested in learning more about the topic of aspiration. Kindly share a link to these studies and I will review.
I guess what I want to know - the short answer - is whether I should go ahead and get a Moderna booster based on average data (I'm in my late 50s, and no special health issues.) My second shot was six months ago, and from what I hear the protection - i.e. antibody levels - will begin to wane about that time. Without getting an antibody test, and just going on average response rates, when is the booster recommended for my age group. This was informative, yet hard to extrapolate into a clear answer for that question. (PS... I don't currently have a relationship with a primary care physician, so there is no one to "ask" for their recommendation.)
Hi - The booster does is authorized but you may not be eligible unless you are at high risk of Covid or you have a high risk of exposure to others based on your job. Still, I would highly recommend to get it as soon as you are eligible. That is what I am planning to do. P.S. On the FDA call with reporters, I heard them say that the "screening" questions about eligibility will be asked at the Pharmacy or wherever you decide to go for the booster shot. If your doctor refers you I think you may have a much better chance.
How is on the first chart Overall results was medium of 3836 u/ml and on next slide is 8000 u/ml and 10000I/ml the medium overall should be 9000 u/ml and not 3836?? When you compared vaccinated and not vaccinated??
Hello sir, I took Moderna vaccine..after the 1st shot I'm suffering from face inflammation and face rashes...after the 2nd shot again rashes and inflammation....in my 24 yrs life i have never faced rashes or inflammation on my face... doctors said they don't know because vaccines are new...what should I do now??
Hi - are you still having these symptoms? They are supposed to monitor you for about 30 minutes after each dose and take immediate action if something like this happens. Were you given any medication? I hope you are all right now.
Sir, rashes were exposed on the 2 Nd day after taking vaccines... I'm using an anti inflammatory cream of bioderma called cicabio...after having the problem a dermatologist suggested me to take roxadex 6mg for 3 days..it worked but for a very short time.only for 2 days..again I'm having issues on my forehead and nose area... there's no other rashes on my body... I don't know what to do... doctors are giving steroids but these worked for a very short time only... I'm really very tensed.
@@nusratjahanprogga1645 Hi sorry to hear this. If you have no prior history, then it is quite unusual. Unfortunately, I am unable to give you any specific medical advice. I know the steroid treatment is often prescribed but I am sure there are other tests and/or treatments they can consider. I hope you are able to get the right medical care and wish you the best.
You want to know what's in these "safe & effective vaccines": Look up the latest research of Dr. Zandre Botha, Dr. Robert Young, Dr. Franc Zalewski, and/or Dr. Carrie Madej. Just to name a few. They all found very disturbing things such as parasites, graphene oxide, aluminum, and other very strange objects that appear to be bio-engineered lifeforms and structures.
not meant to be insulting, but what is your profession? what is the risk for an average person if contracted with the disease? I mean for an average flu, a vaccination is not always necessary, at most only for people of old age or people with other underlying complaints How confident are you to be able to state that these new technology vaccines are safe in the long run, since it can't be proven yet? another question, for example do you share the opinion that it is also necessary to vaccinate children with it? there are still many questions, such as that my government already ordered vaccines to re-vaccinate everyone in 2022,that,s seem including those who already have been vaccinated. (I understand that it is difficult to give your free opinion on this because as I noticed that some dissenting voice is often not being tolerated)
Hi - thank you for sharing your opinions and these questions. You are not insulting me at all, and I appreciate the time you took to share this comment. I do risk management for a living. This is what I have understood after many years of experience in the medical field - 1. It is never a good idea to take a general comment/observation and apply it at an individual level 2. It is never a good idea to take an individual's experience and apply it to the general level 3. tolerance or risk is highly personal and varies from person to person Having said that, I hope you have noticed that in my videos I always say that you should talk to your doctor about your personal situation and risk level. My aim here is to share my understanding of the latest research so we can ask the right questions at an individual level and make good decisions. You ask about "safety" - how safe are these vaccines in the long run. Safety is neither absolute, nor static in time. It is relative to our risk tolerance. So it will mean different things to different people. To understand if a vaccine is safe for you as an individual, you need to talk to your doctor. The research shows it is well tolerated by most, but then as I mentioned before, that conclusion should not mean to apply to everyone at an individual level. Many of the questions you have asked in your comment above, I don't have a good answer. If you want to ask me a more specific question, I will be happy to respond based on what I know. I am also very open about what I don't know. As for dissenting voices, I have no issues as long as they are respectful. I have occasionally received comments that are otherwise, and those are promptly deleted! Thanks again for your comment and please continue to share your opinions. Stay safe and healthy!
Is there a study showing level of IgG for recovered covid19 patients who are not vaccinated? .. I would really like to see the range of IgG compared to vaccinated people as you show in this study frm Belgium.
Hi - good question. I have not come across this data yet. One thing is clear, antibody levels will also drop among those who have recovered and are not vaccinated. So, there will be a point in time where the level of protection will be lower, and they may need to consider vaccination. Otherwise, there is a chance they will get re-infected and then there immune system will once again boost the antibody levels. Assuming everything goes well with the immune response. Hope this helps.
Nicely done, thank you. A question as I'm vaccine hesistant particularly with the limited choices of mRNA cellular level vaccines and their potential long term affects. Would you be able to do a video looking into the likely differences of rMNA, DNA viral vector, and Novovax which I understand is more tradition. I'm happy to get good protection but dosen't have to be at the top of the antibodies list. In my mind it's the long term safety profile that counts more. Many thanks.
Hi - thank you for your comment. When you say "long term safety profile", what are you thinking about? What would you consider as "long term", and what would be "safe" for you? I will certainly take up your suggestion and discuss some of the differences in another video. In general, the 3 vaccines authorized by the FDA are safe and effective. But I always tell people that every individual is different. You should talk to your doctor about the best course of action based on your specific medical situation. Stay safe.
Long term safety profile is say 5 to 15 years. My feelings are there is not enough analysis of information of potential genetic or immunity damage in the long term or even longer term....whereas we know that the traditional type vaccines are safe (based on history). Many thanks
@@reid6462 Hi - the way people understand the mechanism of how the mRNA vaccines (Pfizer, Moderna) and the Adenovirus vector vaccine (J&J and Astra Zeneca) work is there is no negative effect on any genetic changes or natural immunity. If you want to look at 5-15 year timeframe, you can certainly look at other vaccines that are based on the same technology. Hope this helps.
@@NaveenAgarwalPhD my understanding was that the current mRNA vaccines and DNA (vector) are novel, so there is no long term profile yet of genetic vaccines. Many seem to be waiting for Novovax which looks like being a more traditional and therefore tried and tested vaccine in the long term and not likely to present novel problems...e.g like myocardus or vascular problems.
@@reid6462 Hi - Both mRNA and DNA vaccines have been used in the past for other infections. Novavax is protein based. Here is good information on CDC website www.cdc.gov/coronavirus/2019-ncov/vaccines/different-vaccines/how-they-work.html
If you read the research about these vaccines pre-covid, 2018, you will find similar results, works well in the beginning then decreases, and they often conclude with, unwanted side effects and damage to the immune system. So why are they not asking questions regarding these previous studies and applying them? Especially since we are seeing higher and higher infections and death rates among vaccinated people.
Hi - thanks for sharing. This is a good question. Do you have an example in mind for a pre-covid vaccine where this happened? I would like to look into it further.
@@NaveenAgarwalPhDa while back I googled the research to learn more about the technology after listening to some doctors supporting the vaccine and others warning about it. I read several studies and it seemed to me that over the past 30 years they have made much progress but still had not overcome all the problems to make a safe effective vaccine, then suddenly now they did. I read several, mostly reading the abstracts and conclusions, I couldn't tell you any specific one, only that I looked at them online and they raised my concerns. I don't have a medical background so a lot of it was meaningless but certain comments stood out. I think the number one problem is trust.
@@normandowd123 thanks and I understand. I will keep an eye on to see if I can find a specific examples where a vaccine was stopped after initially promoting it. One thing I want to share with you is that the notion of "safety" is not fixed or absolute. It depends on the circumstances and risk tolerance of each individual. What is safe for one may not be safe for another. This is why individual decisions need to be made in consultation with your doctor. I always emphasize this point in my videos. Like everything else in life, nothing is zero risk. All of us have to make our own decisions with the best information available at the time. Public policy takes into account the "greater good", not 100% favorable to everyone. And yes, public policy changes when circumstances change. Stay safe.
Hi - first I am sorry to hear you were infected even after receiving the two doses of Moderna vaccine. Breakthrough infections have been reported, especially as we have seen the Delta variant surge. Vaccines are effective but not 100% and there is always a chance of reinfection based on local conditions and the individual. So it is unfortunate that you had Covid after vaccination and I hope you are doing well now.
Are there specific test for each vaccine name? Do you have to have a Doctor's prescription order; how much is a test? Your report is not so convincing yet.
Hi - are you asking about antibody tests used to generate this data for each vaccine? If so, you can find details in the reference I provided with the video.
Hi Diego - thank you for your question. I made this statement in a general way, not thinking about specific health reasons. The main point is that you should talk to your doctor about your individual decision, with the knowledge of these general facts.
Thanks Doctor, valuable information. Dr. What does strongly positive of Polyclonal antibody score +3, and Monoclonal antibody of MIB -1? A friend diagnosed with breast cancer and she have these numbers of antibody. Thanks.
@@NaveenAgarwalPhD Thanks Dr. for reply. I found some papers that talking of using Polyclonal and Monoclonal especially the later in Cancer treatment. Also both for Covid19 as, you know, they are antibodies.
Hi - as far as I know, there is no effect. Antibodies work against antigens that come from virus, bacteria etc. There are conditions where the immune system attacks itself, but this is not the case for these antibodies.
I have 167u/ml level of antibodies after about 10 months of recovery from covid infection! And the antibodies is the not only immune system type the antibodies will starts to produce more more after reinfected!! And would be also good to see results for antibodies how the decrease after vaccines
Hi - thanks for sharing and that is good news. You are correct, that antibody levels will rise again upon re-infection. They also rise in response to receiving a vaccine. You are also correct that there is a cellular component to immunity. To your question about drop in antibody levels after vaccination, there is now data available. You can watch this video for my latest update czcams.com/video/cW9LJs1qFQ8/video.html
Data doesn’t alow you to fairly suggest convenience of vaccination for COVID recovered, because there was no comparison between vaccinated versus none vaccinated. Also there is no basis for your conclusion that vaccines raised antibody levels of COVID recovered population, because neither safety nor effectiveness was studied in vaccinated versus none vaccinated COVID recovered population..
Hi - could you please clarify your question/comment? Also, which specific data are you looking at in my video when making the statement about antibody levels for those who had a prior infection before getting the vaccine?
Is there any estimate yet from available data on how long the booster shot will provide protection? Is it expected to wane similarly to the 2-dose regimen at around 6 months or will it provide more long-term protection at a higher level? I was fully vaccinated in mid February and trying to be strategic in timing my booster shot for some scheduled travel in April. In the meantime, I am feeling vulnerable and avoiding certain situations where I could be exposed.
Hi - thanks for your question. The data on boosters is too new to fully answer this question. But we can expect similar results. Data shows that mRNA vaccine (and booster) results in a faster antibody response, but they also peak more quickly. Good news is that you will have all three vaccine boosters available if you qualify. Talk to your doctor for more specific advice. Best wishes and stay safe.
I get very layman understanding of these things but I’m a bit confused. Am I right in assuming that the T cell response is the longer lasting response that will ultimately be the guide to whether you get reinfection or not, and that you get that response if you’ve had a high B cell response at some point even if that response subsequently wanes. If that’s true or partially true then how much truth is there that the mRNA vaccines are generating B cell responses but not great T cell response, especially compared to natural infection?
Hi I found you're video very good and very informative. My current igg antibody's are still showing 2500 >u/ml 13 months after 2 vaccine doses and don't seem to be dropping below this amount. Could you tell me any explanation why this would be and does this mean I don't require a 3rd dose of the vaccine if they remain this high ? Thanks
Sir, your demonstrations and explanations about antibody levels are clear and concise. Four days ago I received my third dose of the Pfizer-BioNTech vaccine, which was exactly six months after my second dose. I have not taken an antibody test.
Hi can you please explain Dr Richard Flemming nuclear cardiologist work can this we get ADE or cytocline storms. Also what do you think of Dr geert von dussche work is safe to get shot
I think the men you listed are grifters profiting off disinformation. Talk with your doctor about whether or not it’s safe for you to get the vaccine. Your doctor should be able to answer all your questions and you can decide how to proceed.
@@Jupiter_Crash hahaha I already know I actually imposed the question... You said I think??? And dis information.? Go get a D dimmer test.... And T cells count done.. and go understand agenda 2030 . And the great global reset. You have no clue on evil that comes.
Thank you for your great video explanations. Being 72 years old, retired and no major health issues, never got COVID, I was hesitant at first to get the shots, but now have just taken the first two shots of Pfizer. I only had a sore arm and little fatigue, next day felt fine. No idea what my antibody levels will get to in the weeks to come. My question is because of my age, from now on are we going to have to get COVID booster shots every year like the flu shot(which I also get)? The unknown in your video is how long are we somewhat protected after Vaccines? I assume COVID virus will be around from now on and will probably be spikes in COVID activity in the US. I also still follow CDC guidelines for protection(mask, distancing, etc) in public places. take care.
Hi - great question and I am happy to hear you did not have any serious side effects to the vaccine. This is a common experience and that is why these vaccines (in general) are considered safe and effective. To your question about how long the protection is expected to last, generally they have seen the antibody levels to remain sufficiently high for 6 months. But that will be different for each individual. The risk is reduced by a lot, but it is not zero. Every individual needs to look at their unique situation and talk to their doctor so they can make the right decision. Best wishes to you and stay safe.
I have an auto immune since 2014 without needed of treatment until I got first dose of Pfizer I feel some thing wrong in my body so I did talked to my GP and did blood test , found out that my ANA level was elevated as well as Esr, Crp so I’m scared to have second dose as it potentially make my anti body stronger and will have more ability to attack my own cell, I don’t want to come to the point that I have to be on immuno suppressant.
Hi - thank you for sharing. It is good that you are talking to your doctor. You are doing the right thing by being careful and seeking medical advice from your doctor. Best wishes to you and stay safe.
I am been very sick after my first Pfizer jab all my test are clear only my iron levels were toward lower range … after 14 weeks I still have nausea and Bp fluctuations and heart palpitations… never had any health issues before Pfizer I am so worried to get second jab
@@shinningstar9650 Hi - I am sorry to hear about your experience? Are you in the US? FDA has now authorized mix-and-match vaccine boosters. That means you may be able to get another vaccine instead of Pfizer. Talk to your doctor if this might an option for you. Best wishes.
@@NaveenAgarwalPhD I am in Australia and the Vic safe has high volume of adverse effected reported they still have to get back to me with advise it’s nearly my 14 week
Hi - yes individual factors will affect how their immune system responds to the infection. What is more important is to see how it changes over time for the individual. These results provide general guidance but we cannot conclude that every single person will show a similar level of antibodies. In general, vaccine data is clearly showing that your chances of getting severe covid or getting hospitalized are much lower if you got the vaccine vs if you did not. But vaccine is not 100% effective as we have seen. Nothing is 100% from that point of view. We make the best decision we can based on available information and in consultation with our doctor. Best wishes and stay safe.
I am Italian and my mum in her 70 took astrazeneca and before the 2nd shot She had 76.22 u/ml, while After 1 month and half She had only 4.62 au/ml ( the test was differenti from the First Who was the Roche One) and the conclusion was She had a little responsivity. She Is very worried. The doctor said to be calm and wait to do a 3rd shot.
Hi - yes different tests give different numbers, so it is not possible to directly compare the two numbers. I think the doctor's recommendation is correct. For her age a booster shot should be recommended. When is it going to be available in your area? In the US, the FDA has just authorized a third booster shot for the Pfizer vaccine. See this video here czcams.com/video/RXM1reL7UIw/video.html
@@NaveenAgarwalPhD here in Italy the booster is only with Pfizer's or Moderna's, even if you have been vaccinated with Astrazeneca or Johnson. But not before six months since the second shot done. So my mom can not receive her third shot until the end of january and we are not so relaxed also because the weather is getting cold.
Hello - honestly, it is not clear right now but things are pointing in that direction. If the virus continues to mutate, we will have the need to continue boosting antibody levels using booster shots.
Hi - I think this is a matter of personal decision. Everyone evaluates benefit-risk differently. To some, they don't want to take this vaccine, no matter what. They would be willing to give up anything. To others, it seems unreasonable. My perspective is that I cannot judge other people's decisions. I just hope they are making this decision based on full information, and most importantly, not based mis-information. It is best to make a decision to take or not take any vaccine in consultation with your doctor. Best wishes and stay safe.
If you don’t have a direct comparision between COVID recovered population which took versus didn’t take vaccine regarding effectiveness and safety, you should not derive any conclusions regarding recommendations of a COVID recovered population, whether they should or not be vaccinated. The study you showed doesn’t allow the conclusions you derived from it.
I just did a test in quest the result is positive but I do not understand the number :Your COVID-19 Antibody Test (SARS-CoV-2 AB IgG), Semi-Quantitative Result COVID-19 Antibody Test (SARS-CoV-2 AB IgG), Semi-Quantitative POSITIVE Current Result >20.00 index Reference Range
I have a question. Almost 2 months ago 3 of us in our family contracted the covid virus. it took us 3 weeks to recover from the ilness. As a matter of fact, because of my asthma, I still have a lingering cough. Thankfully it is slowly going away. My question is: "How long do we have to wait, after being sick from covid and fully recovering, to take the vaccine so that it is the most effective in producing more anti bodies?" I think it is also important to mention that none of us has ever received a vaccination for covid. I have had mixed answers from nurses and doctors alike. Some say 2 months, some say 3 months. My doctor that I visited after a week from recovering (4 weeks total from the time of the first symptoms), told me I can get it right away. So, I am still confused. Till this day we still have not received any vaccine. We are waiting after 2 months which will be on October 25th. But I would still like an answer out of curiosity and of course, to be sure we are not taking it too early. Thank you Doctor Agarwal. I will share this video with others. Liked and subscribed.
Hi - thank you for your question. First, I am happy to hear you and your family have recovered. I have not come across any specific guidance on waiting period before getting the vaccine if you have had a prior infection. I believe it has more to do with the local policy. In many areas, there is still a shortage of vaccines. So, they may have a policy of prioritizing those who did not have the infection before. If we were to assume that the first dose causes a "mild" infection - then the waiting period for the 2nd dose of the mRNA vaccine is about a month. That is the only thing I can think of - maybe wait a month before getting your first shot of the vaccine.
@@NaveenAgarwalPhD Take out "better" and just answer if you already had the virus, you likely have antibodies including T and C cells. Studies have shown one shot of any of the available vaccines increase antibodies. The second shot seems to do nothing further. I can find the studies if needed. What those of us who had this wretched virus want to know, is why is "super" immunity "better"? What are the chances of reinfection?
@@001LADen Thank you. As it turns out, I have found a very recent paper in the journal Science which directly compares the immune response between people who didn't have an infection before and got the vaccine, and those who had a prior infection then got the vaccine (both cases - 2 doses of mRNA). Stay tuned, I will be talking about this in a future video. I am definitely interested in this question, not from the point of view of "better" or "super immunity", but really understanding how our immune systems are responding. Of course, each individual is different, but we can get some general understanding. Thanks again and stay tuned. P.S. if you do find studies that are relevant, please share. I will review them.
I think to help with "what is a good level of antibody" for the average person to have protection, they should be testing antibody levels on break through cases using the same testing protocol, along with documenting as much as possible (Ex: is the person asymptomatic, or had alot of symptoms). This should help with some kind of numbers to determine if a booster is required down the road.
Hi - great point and thank you for sharing. This is an important question and I am sure many people are studying this right now. I am keeping my eyes on it. As soon as I learn something new, I will make another video.
Thank you so much DR for the in-depth analysis. I was wondering if I have had a robust immune response to my vaccine doses (body aches, fever, swollen lymph) does that mean I would have a higher antibody count or isn't it as simple as that? Thank you so much for any help you can provide.
Hi - in general, this could be true. However, the antibody response is mounted by the immune system only after it has learned the exact type of the antigen. Or it is using the memory from an earlier infection. That is the role of the T cells who gather this information and pass on to the B cells. B cells with specific antibodies then proliferate quickly to block the progression of the pathogen (in this case the coronavirus). So the initial "robust" response with strong symptoms could be due to the initial action of the T cells and other parts of your immune system. This of course is all theoretical speculation - the best way to learn will be to do a semi-quantitative or quantitative antibody test.
Would have been interesting, what the Antibody level was prior vaccination, of the people who have been infected. But this was interesting, and I am happy I got Moderna, and waiting for the booster. ( working in Health care and it's been 9 mo ) Thanks for the information
Hi - we can look at the baseline data from their clinical trial study. They measured starting antibody levels for everyone who participated in the trial. All show very low levels. Good news for you is that the Moderna booster is going to get the emergency use authorization very soon. Thanks for your service in healthcare. Wishing you all the best and stay safe.
Hello doctor I had 2 doses of Pfizer the first shot was ok 👍 but the 2nd shot I had really strong response I was sick for 9 days (headache, body aches., fever for 2 days , foggy brain and dizziness ) does it mean that I have high antibodies? Taking in consideration that I had the 2nd shot after 4 weeks from the first shot , unlike my friends who didn’t get a strong response on both shots !!
Hi - sorry you had such a strong response to the 2nd dose. The only way to tell if you have higher level of antibodies is to test. Antibodies are only part of the total immune response.
@@001LADen by "total", I think you mean both antibodies and B&T memory cell response, right? The answer is yes. In the paper I am reviewing right now, they are showing clear data. Thank you for your good questions. I think all of us should be asking these questions to better understand all the info that is coming at us.
@@NaveenAgarwalPhD I look forward to your upcoming videos. I stumbled on this video today. Short, to the point, explained alot in layman's terms. I still don't quite understand why I should take the vaccine when I have all the components from a natural infection. I'm not anti-vax, I just know from others who had C19, the reactions to the vax shot is not enjoyable. My own MD recommended only 1 shot. But that leaves me 1/2 vaxed. czcams.com/video/yfMlVXUgzoE/video.html
@@001LADen - The mRNA vaccines only focus on the S-protein. The breadth and depth of the immune response regarding the S protein is really good especially regarding the RBD (receptor binding domain.) it’s higher than natural infection. Natural infection in about 80% of people will create immune response to N protein, E protein, and S protein. The downside to natural infection are the risks and not knowing if you’re in the 20% range that won’t launch an adequate response to future infections. Plus, they don’t know yet how long natural immunity lasts. I’m sure more data are coming to answer that.
Fully vaccinated ever since April2021, and in june i had an antibody test done at Quest and results were negative. So whats going on? These vaccine dont work.
@@yautjaxenomorph9472 Hi - thank you for confirming. In some cases, the immune response may take longer to produce enough antibodies for a test to detect. Moderna antibody data shows a very large range, although the average values are very high at their peak level. I would have recommended a second test, but it has already been 6 months for you. Still, it wouldn't hurt to confirm.
What was the test detecting? Did you use T-detect or some other test? If so, those test are testing for the N-protein which you’ll only have if you’ve been naturally infected. The vaccines antibodies will only produce antibodies for the S-protein.
The data is clear on vaccinations so why aren't we asking if boosters should be less a priority than Vax getting to 3rd world?!! You can't eliminate new strains from developing when the whole continent of Africa is virtually unvaccinated!
Hi - you raise a valid point. This is a policy issue. I think there is broad recognition that this is a global issue and that every one in the world should have access to a safe and effective vaccine. Having said that, each country will make policies to serve the interests of their own population. Hopefully, this will all come together at the global scale.
Hi - to make sure I understand correctly - are you asking about the severity of symptoms if someone gets re-infected and they haven't had the vaccine? So this would be a repeat infection after a prior infection. Correct? I haven't seen any specific studies that target this question. I will keep this in mind and share if I come across anything.
@@automech01 Hi - I think one way to look at this would be to review the hospitalization rates and/or ICU admissions among non-vaccinated patients who had a prior infection and now re-infected. I would expect that number to be similar to what they are reporting now where a majority of hospitalized patients are non-vaccinated. I think you are also likely to see risk factors such as age, other medical conditions etc. to play a role. Thank you for your question and sharing your thoughts!
@@automech01 No it is not. Natural infection also protects you from severe disease upon re-infection. Of course, receiving a single (or even double) dose of an mRNA vaccine on top of that can only benefit you (no downsides). Listen what a giant of vaccinology, Paul Offit, has to say on the subject... czcams.com/video/v8eOQSRVh_s/video.html
Hi - Did they tell you which specific antibody test they used? Greater than 20 means the number was above their upper limit. but this upper limit seems low to me.
@@vvssa301 Ok thanks for the info. This is unusual but you can understand this as having antibodies in your system. Keep in mind that the antibody level will generally go down over time and there is no "magic" number that relates to a level of immunity. Continue to take precautions to protect yourself from re-infection.
Hi Cheryl - so the latest is that Moderna has submitted a data package to the FDA for authorization of the booster dose. A decision could come as soon as tomorrow (Oct 14). I will be following up on this.
Hi - a mild cold could be a symptom of something else, not necessarily a breakthrough Covid infection. The best way to confirm would be to do another test. In terms of data on breakthrough case, CDC has a lot of good information on this link www.cdc.gov/coronavirus/2019-ncov/vaccines/effectiveness/why-measure-effectiveness/breakthrough-cases.html
Thank you for this video it’s very informative, however I have a concern I was hoping you might address. I am a 52 year old male and I had acute ITP in 2015 at a level of 20 when normal range should be 200 to 450 I believe. They were not sure what had caused it - may be a virus infection… It was treated with steroids prednisone 100 mg per day for 2 months , and my platelets have been proper ever since averaging around the 225 mark. In hearing about clotting and platelet issues I was extremely anxious and nervous to get a COVID vaccine however I took a leap of faith and received the Pfizer vaccine and last dose was last June . Both doses gave me very little side effects. Sore arm and a bit tired but that was it. My platelets seemed OK as I did not experience any of the symptoms that I had had in 2015 of Petechia rash etc. In hearing now that the booster shot increases antibody proteins to elevate almost double of what the first two doses gave us, should I be concerned that this high antibody protein level may trigger another low platelet situation.? Please kindly advise. Thanks. ⭐️⭐️⭐️⭐️⭐️
Hi - thanks for your question. I am not familiar with ITP, but looks like you tolerated the first two doses of the Pfizer mRNA vaccine quite well. One point I want to clarify is that the booster dose does not generate "antibody proteins". The antibodies are complex structures that basically "capture" an antigen, which could be a protein, or part of a protein structure from the virus. The booster dose from Pfizer is no different in its composition and amount of mRNA compared to the first two doses of the primary series. If you tolerated the first two doses well then it will be highly unlikely that the booster dose triggers some kind of a new response, including low platelet levels. Still, it is best to consult with your doctor. Maybe you can do a test to measure your platelets before you take the booster dose and closely monitor it afterwards. Best wishes and stay safe.
@@NaveenAgarwalPhD Thank you so much for your response. It eases my mind and makes me feel better. My doctor has advised the same. Highly unlikely would be different reaction on third dose , but I just wanted to get your take on it. Thanks so much. 🙂
@@NaveenAgarwalPhD perhaps I had worded it incorrectly, you were speaking that certain levels of a certain component was almost double and much higher than the first two doses. I was just concerned that these high levels of that certain component might trigger a platelet issue. Thank you for your feedback I appreciate it. 💉
@@joeyvee4968 Hi- thank you for your comment. I am not sure which component I mentioned, but can you remind me what you saw in the video that prompted you to think about this issue? Is it the mRNA amount in the Moderna booster? That is the only thing that comes to my mind because the Moderna booster contains only half as much mRNA as the initial first two doses. But let me know if you are thinking of something else.
@@NaveenAgarwalPhD pardon me doctor Agarwal , I am referring to the level of antibodies in the 3rd dose of Pfizer. I believe The levels are significantly higher almost double of the combined first two doses of Pfizer. I was concerned that these much high antibodies can trigger platelet reduction. Of course I don’t fully understand the dynamics involved , hence why I seek clarity. I’m sorry if my terms are not on point. Thank you.
Had Covid in April, checked antibody level in September and it was 58. Got my first dose of Moderna in October, had my antibodies rechecked last week and they were at 2,500. My question is, do I need a second dose or can I wait?
Hi - thank you for the question. You need to take the second dose as prescribed to be considered fully vaccinated. Can you share why you are considering to wait?
@@NaveenAgarwalPhD Thanks for the reply. Yes, I’m torn on whether or not to go. I’m suppose to get my second dose Tuesday, but not sure I want to just yet. People should be considered fully immunized with one dose of an MRNA vaccine after they’ve had Covid, but that doesn’t seem to be the case and I don’t want to only be considered partially vaccinated.🤦🏻♀️
@@michelemclaughlin4474 Hi - yes that is a good point. But right now, you have to complete both doses for the primary vaccine series to be considered complete. What does your doctor say?
My seafarer husband Is being required by his company to get vaccinated, he will comply even if he doesn't want to for both of us believed the vaccines can do no good to our bodies. My question is..can he somehow expel or remove the vaccine in his body the natural way?
Hi - are you asking if somehow the body can expel all of the vaccine without affecting the immune system? I am not aware that this can be possible. Do you feel this way about this specific vaccine (covid19) or do you hold this view for all vaccines that they "can do no good to our bodies"?
@@aye1556 Please read this description of how vaccines work on CDCs page www.cdc.gov/coronavirus/2019-ncov/vaccines/different-vaccines/how-they-work.html
I have the SARS-CoV-2 Semi-Quant Total Ab test 8/31/21. Result was positive 68.6 The LabCorp report doesn't explain what that number indicates. My MD also cannot explain it other than to say it indicates I had COVID-19 and I should get at least on shot of a vaccine. Perhaps I'm missing the point on why super immunity is better? Antibodies wane after infection and after vaccination. Shouldn't memory B and T cells still exist?
Hi - These are two different ways our immune system fights an infection. In the end, you do need neutralizing antibodies that will block the pathway through which the virus attaches to cell receptors and continues to multiply. Commercially available antibody tests give the total number of antibodies, and not specifically neutralizing antibodies. The two are correlated, meaning if the total amount is high, then the neutralizing antibody amount is also high. But we can't be sure of how much. Memory cells will create a memory, but neutralizing antibody needs to be available to block the transmission.
@@NaveenAgarwalPhD Thx you for the quick reply. How long do neutralizing antibodies last? The whole C19 booster plan is confusing when other viruses, such as mumps, measles, don't require a booster.
@@001LADen You are welcome. Yes, the level of neutralizing antibody does go down over time. See this video I just released where I discuss the data on Pfizer vaccine booster shot czcams.com/video/RXM1reL7UIw/video.html I agree, the C19 booster plan is confusing - it is needed because we still have very high rates of transmission in certain areas and many people are still at risk, even those who have already received 2-doses of this vaccine.
I believe I had that same test. Well, on the test results mine was called SARS-CoV-2 Spike Antibody test. Maybe mine was slightly different than yours. I had mine drawn on 10/4/21 which was almost exactly a year from when I initially had symptoms. My level was 654. I wish there was more info on these different Covid antibody tests. There are several types and I don't know how they correlate and why one test might be ordered over another.
@@Joe_Friday Hi - the "spike antibody test" name means that it can detect antibodies that bind to the spike protein of the virus. Only some of these may act as neutralizing antibodies. It is good to see your test result showed a pretty good level (again, compare it to the range of the test to be sure) after 1 year. What kind of other questions do you have about antibody tests? I will be happy to look into it and discuss in future videos.
Hi - this is a very good question. It depends on your individual situation. Generally, the level of antibody drops over time. There may be some individuals who may be at a higher risk because of this - either their antibody levels were low to begin with, or they have dropped to a very low level. That is why it is a very individual decision that should be taken after consulting with your doctor. What the FDA is doing is creating a lot of flexibility for the doctors by clearing the regulatory barriers. Hope this helps.
@@joyfuljoyful6598 Yes that is correct. Re-infection is always possible even for those who took the vaccine more than 6 months ago. There is general concern that the immunity levels in the population are dropping and with new variants emerging fast, we have to worry about protection against serious illness. Especially those who are particularly vulnerable from a health point of view.
@@NaveenAgarwalPhD One would think that promoting strengthening your immunity with other natural alternatives would be a far safer alternative for those who are immuno suppressed or with other issues that may course adverse reactions with the vaccine. Surely promoting the use of Vit D3, K2, Zinc, Magnesium and vitamin C or even Manuka honey, is just as beneficial as the vaccine. I wouldn't want a protein running rampant in my body.
Hi - Thanks for your comment. I agree, this is a very complex topic. That is why I am trying to offer a simple explanation in my videos after reviewing the technical papers. Let me know which part you would like to understand better.
@@Jupiter_Crash Hi - yes, and like you, I am also learning. This discussion helps a lot. Please continue to share your thoughts, comments and questions.
Hi - only two things are certain in life - death and taxes! We have to make decisions in light of uncertainty. And every individual is different. Their risk tolerance is different. They make decisions differently. Would you agree?
So sir please tell what antibodies numbers are highest and lowest then in order to guide people on the decision to booster or not. How are we sure the booster won't affect natural immunity? Will it be better or will it lessen at the least?
@@raymundpadilla3619 The best guidance will come from your doctor at an individual level. There is currently no generally accepted "level" of antibodies that is considered to be required as a minimum for maintaining your level of protection. Also, note that antibodies are only one part of the total immune response. So the short answer is - it depends on your own individual situation. What we have is a number of options available to give this flexibility in decision making. To your question about effect on "natural immunity", it has been shown that a booster dose actually stimulates the immune response. Overall risk profile is no different than the primary series and there are no new safety risks. Again, let me emphasize - this does not mean it is "zero risk". Risk will also depend on the individual level. Hope this helps.
Well presented, sir. You answered all my questions about antibodies. I love that you added, "Continue to take precautions."
Thank you!
I found this video extremely helpful after having my serology test results. I was able to benchmark that with the Belgium study and reaffirmed my decision to proceed with a booster shot. Thanks for simplifying the Covid test results and making it easy to understand,

@@NaveenAgarwalPhD hello Dr Argawal, I took monoclonal antibodies July 26, they told me to wait 90 days, before taking the covid vaccine, I was wondering if I can take my vaccine tomorrow, which is 2 days short of my 90 days, Thank You
@@zachsiatrevor antibody was for covid treatment? Or were you given monoclonal antibodies for another condition?
@@NaveenAgarwalPhD yes sir, for covid
@@zachsiatrevor Hi - in that case, I don't see any harm in taking the vaccine on day 88! Generally, the antibody levels are expected to drop after about 50 days or so. I think you were advised to wait this long to make sure the monoclonal antibody level was not compromised by the antibodies created stimulated by a vaccine. But you should do a final check with your doctor.
Stay safe and best wishes.
Thank you for your service sir. I am so lucky to come across your video. This is a gift to our Humanity
Very detail and sound explanations, thank you.
Thank you!
I have had two moderna vaccines and had minimal adverse effects. I have read would be best to aspirate before injecting vaccine to make sure no blood vessel was entered to minimize relatively rare heart/coagulation adverse effects. Most vaccine centers do not aspirate and wonder if more studies coming. The few studies were from Europe and hope more standardized procedures are put in place. Thank you for posting this informative video!
Hi - very interesting and thank you for sharing this info. I would be interested in learning more about the topic of aspiration. Kindly share a link to these studies and I will review.
I guess what I want to know - the short answer - is whether I should go ahead and get a Moderna booster based on average data (I'm in my late 50s, and no special health issues.) My second shot was six months ago, and from what I hear the protection - i.e. antibody levels - will begin to wane about that time. Without getting an antibody test, and just going on average response rates, when is the booster recommended for my age group. This was informative, yet hard to extrapolate into a clear answer for that question. (PS... I don't currently have a relationship with a primary care physician, so there is no one to "ask" for their recommendation.)
Hi - The booster does is authorized but you may not be eligible unless you are at high risk of Covid or you have a high risk of exposure to others based on your job. Still, I would highly recommend to get it as soon as you are eligible. That is what I am planning to do.
P.S. On the FDA call with reporters, I heard them say that the "screening" questions about eligibility will be asked at the Pharmacy or wherever you decide to go for the booster shot. If your doctor refers you I think you may have a much better chance.
How is on the first chart Overall results was medium of 3836 u/ml and on next slide is 8000 u/ml and 10000I/ml the medium overall should be 9000 u/ml and not 3836?? When you compared vaccinated and not vaccinated??
Hello sir, I took Moderna vaccine..after the 1st shot I'm suffering from face inflammation and face rashes...after the 2nd shot again rashes and inflammation....in my 24 yrs life i have never faced rashes or inflammation on my face... doctors said they don't know because vaccines are new...what should I do now??
Hi - are you still having these symptoms? They are supposed to monitor you for about 30 minutes after each dose and take immediate action if something like this happens. Were you given any medication? I hope you are all right now.
Sir, rashes were exposed on the 2 Nd day after taking vaccines... I'm using an anti inflammatory cream of bioderma called cicabio...after having the problem a dermatologist suggested me to take roxadex 6mg for 3 days..it worked but for a very short time.only for 2 days..again I'm having issues on my forehead and nose area... there's no other rashes on my body... I don't know what to do... doctors are giving steroids but these worked for a very short time only... I'm really very tensed.
@@nusratjahanprogga1645 Hi sorry to hear this. If you have no prior history, then it is quite unusual. Unfortunately, I am unable to give you any specific medical advice.

You want to know what's in these "safe & effective vaccines": Look up the latest research of Dr. Zandre Botha, Dr. Robert Young, Dr. Franc Zalewski, and/or Dr. Carrie Madej. Just to name a few.

not meant to be insulting, but what is your profession?
what is the risk for an average person if contracted with the disease?
I mean for an average flu, a vaccination is not always necessary, at most only for people of old age or people with other underlying complaints
How confident are you to be able to state that these new technology vaccines are safe in the long run, since it can't be proven yet?
another question, for example do you share the opinion that it is also necessary to vaccinate children with it?
there are still many questions, such as that my government already ordered vaccines to re-vaccinate everyone in 2022,that,s seem including those who already have been vaccinated.
(I understand that it is difficult to give your free opinion on this because as I noticed that some dissenting voice is often not being tolerated)
Hi - thank you for sharing your opinions and these questions. You are not insulting me at all, and I appreciate the time you took to share this comment.
I do risk management for a living. This is what I have understood after many years of experience in the medical field -
1. It is never a good idea to take a general comment/observation and apply it at an individual level
2. It is never a good idea to take an individual's experience and apply it to the general level
3. tolerance or risk is highly personal and varies from person to person
Having said that, I hope you have noticed that in my videos I always say that you should talk to your doctor about your personal situation and risk level. My aim here is to share my understanding of the latest research so we can ask the right questions at an individual level and make good decisions.
You ask about "safety" - how safe are these vaccines in the long run. Safety is neither absolute, nor static in time. It is relative to our risk tolerance. So it will mean different things to different people. To understand if a vaccine is safe for you as an individual, you need to talk to your doctor. The research shows it is well tolerated by most, but then as I mentioned before, that conclusion should not mean to apply to everyone at an individual level.
Many of the questions you have asked in your comment above, I don't have a good answer. If you want to ask me a more specific question, I will be happy to respond based on what I know. I am also very open about what I don't know.
As for dissenting voices, I have no issues as long as they are respectful. I have occasionally received comments that are otherwise, and those are promptly deleted!
Thanks again for your comment and please continue to share your opinions.
Stay safe and healthy!
Is there a study showing level of IgG for recovered covid19 patients who are not vaccinated? .. I would really like to see the range of IgG compared to vaccinated people as you show in this study frm Belgium.
Hi - good question. I have not come across this data yet. One thing is clear, antibody levels will also drop among those who have recovered and are not vaccinated. So, there will be a point in time where the level of protection will be lower, and they may need to consider vaccination. Otherwise, there is a chance they will get re-infected and then there immune system will once again boost the antibody levels. Assuming everything goes well with the immune response.
Hope this helps.
Nicely done, thank you. A question as I'm vaccine hesistant particularly with the limited choices of mRNA cellular level vaccines and their potential long term affects. Would you be able to do a video looking into the likely differences of rMNA, DNA viral vector, and Novovax which I understand is more tradition. I'm happy to get good protection but dosen't have to be at the top of the antibodies list. In my mind it's the long term safety profile that counts more.
Many thanks.
Hi - thank you for your comment. When you say "long term safety profile", what are you thinking about? What would you consider as "long term", and what would be "safe" for you?
I will certainly take up your suggestion and discuss some of the differences in another video.
In general, the 3 vaccines authorized by the FDA are safe and effective. But I always tell people that every individual is different. You should talk to your doctor about the best course of action based on your specific medical situation. Stay safe.
Long term safety profile is say 5 to 15 years. My feelings are
there is not enough analysis of information of potential genetic or immunity damage in the long term or even longer term....whereas we know that the traditional type vaccines are safe (based on history).
Many thanks
@@reid6462 Hi - the way people understand the mechanism of how the mRNA vaccines (Pfizer, Moderna) and the Adenovirus vector vaccine (J&J and Astra Zeneca) work is there is no negative effect on any genetic changes or natural immunity. If you want to look at 5-15 year timeframe, you can certainly look at other vaccines that are based on the same technology.
Hope this helps.
@@NaveenAgarwalPhD my understanding was that the current mRNA vaccines and DNA (vector) are novel, so there is no long term profile yet of genetic vaccines. Many seem to be waiting for Novovax which looks like being a more traditional and therefore tried and tested vaccine in the long term and not likely to present novel problems...e.g like myocardus or vascular problems.
@@reid6462 Hi - Both mRNA and DNA vaccines have been used in the past for other infections. Novavax is protein based. Here is good information on CDC website
www.cdc.gov/coronavirus/2019-ncov/vaccines/different-vaccines/how-they-work.html
If you read the research about these vaccines pre-covid, 2018, you will find similar results, works well in the beginning then decreases, and they often conclude with, unwanted side effects and damage to the immune system. So why are they not asking questions regarding these previous studies and applying them? Especially since we are seeing higher and higher infections and death rates among vaccinated people.
Hi - thanks for sharing. This is a good question. Do you have an example in mind for a pre-covid vaccine where this happened? I would like to look into it further.
@@NaveenAgarwalPhDa while back I googled the research to learn more about the technology after listening to some doctors supporting the vaccine and others warning about it. I read several studies and it seemed to me that over the past 30 years they have made much progress but still had not overcome all the problems to make a safe effective vaccine, then suddenly now they did. I read several, mostly reading the abstracts and conclusions, I couldn't tell you any specific one, only that I looked at them online and they raised my concerns. I don't have a medical background so a lot of it was meaningless but certain comments stood out. I think the number one problem is trust.
@@normandowd123 thanks and I understand. I will keep an eye on to see if I can find a specific examples where a vaccine was stopped after initially promoting it.
One thing I want to share with you is that the notion of "safety" is not fixed or absolute. It depends on the circumstances and risk tolerance of each individual. What is safe for one may not be safe for another. This is why individual decisions need to be made in consultation with your doctor. I always emphasize this point in my videos.
Like everything else in life, nothing is zero risk. All of us have to make our own decisions with the best information available at the time.
Public policy takes into account the "greater good", not 100% favorable to everyone. And yes, public policy changes when circumstances change.
Stay safe.
i dont know doctor what you talking but i know that after 2 dosages of Moderna in February I got COVID Delta in August and I was pretty bad sick
Hi - first I am sorry to hear you were infected even after receiving the two doses of Moderna vaccine. Breakthrough infections have been reported, especially as we have seen the Delta variant surge. Vaccines are effective but not 100% and there is always a chance of reinfection based on local conditions and the individual. So it is unfortunate that you had Covid after vaccination and I hope you are doing well now.
Interested to note thanks fir this info
I got an antibody test around 3 months after infection and got a 4.97 number from Quest Diagnostics. They indicated that it was high.
Hi - this shows that your immune system responded to the infection. This is good news. Did they say anything more than just "it was high?".
Are there specific test for each vaccine name? Do you have to have a Doctor's prescription order; how much is a test? Your report is not so convincing yet.

Data doesn’t alow you to fairly suggest convenience of vaccination for COVID recovered, because there was no comparison between vaccinated versus none vaccinated. Also there is no basis for your conclusion that vaccines raised antibody levels of COVID recovered population, because neither safety nor effectiveness was studied in vaccinated versus none vaccinated COVID recovered population..
Jesus christ you sound like Ben Shapiro meaning you say nothing with alot of words
Hi - could you please clarify your question/comment? Also, which specific data are you looking at in my video when making the statement about antibody levels for those who had a prior infection before getting the vaccine?
Is there any estimate yet from available data on how long the booster shot will provide protection? Is it expected to wane similarly to the 2-dose regimen at around 6 months or will it provide more long-term protection at a higher level? I was fully vaccinated in mid February and trying to be strategic in timing my booster shot for some scheduled travel in April. In the meantime, I am feeling vulnerable and avoiding certain situations where I could be exposed.
Hi - thanks for your question. The data on boosters is too new to fully answer this question. But we can expect similar results. Data shows that mRNA vaccine (and booster) results in a faster antibody response, but they also peak more quickly. Good news is that you will have all three vaccine boosters available if you qualify. Talk to your doctor for more specific advice. Best wishes and stay safe.
@@NaveenAgarwalPhD thank you for responding!
I get very layman understanding of these things but I’m a bit confused. Am I right in assuming that the T cell response is the longer lasting response that will ultimately be the guide to whether you get reinfection or not, and that you get that response if you’ve had a high B cell response at some point even if that response subsequently wanes. If that’s true or partially true then how much truth is there that the mRNA vaccines are generating B cell responses but not great T cell response, especially compared to natural infection?
Hi - thanks for your question. I will look into this topic and follow up.

Thank you for your great video explanations. Being 72 years old, retired and no major health issues, never got COVID, I was hesitant at first to get the shots, but now have just taken the first two shots of Pfizer. I only had a sore arm and little fatigue, next day felt fine. No idea what my antibody levels will get to in the weeks to come. My question is because of my age, from now on are we going to have to get COVID booster shots every year like the flu shot(which I also get)? The unknown in your video is how long are we somewhat protected after Vaccines? I assume COVID virus will be around from now on and will probably be spikes in COVID activity in the US. I also still follow CDC guidelines for protection(mask, distancing, etc) in public places. take care.
Hi - great question and I am happy to hear you did not have any serious side effects to the vaccine. This is a common experience and that is why these vaccines (in general) are considered safe and effective.
To your question about how long the protection is expected to last, generally they have seen the antibody levels to remain sufficiently high for 6 months. But that will be different for each individual. The risk is reduced by a lot, but it is not zero. Every individual needs to look at their unique situation and talk to their doctor so they can make the right decision. Best wishes to you and stay safe.
I have an auto immune since 2014 without needed of treatment until I got first dose of Pfizer I feel some thing wrong in my body so I did talked to my GP and did blood test , found out that my ANA level was elevated as well as Esr, Crp so I’m scared to have second dose as it potentially make my anti body stronger and will have more ability to attack my own cell, I don’t want to come to the point that I have to be on immuno suppressant.

Hi - yes individual factors will affect how their immune system responds to the infection. What is more important is to see how it changes over time for the individual. These results provide general guidance but we cannot conclude that every single person will show a similar level of antibodies. In general, vaccine data is clearly showing that your chances of getting severe covid or getting hospitalized are much lower if you got the vaccine vs if you did not. But vaccine is not 100% effective as we have seen. Nothing is 100% from that point of view. We make the best decision we can based on available information and in consultation with our doctor. Best wishes and stay safe.
I am Italian and my mum in her 70 took astrazeneca and before the 2nd shot She had 76.22 u/ml, while After 1 month and half She had only 4.62 au/ml ( the test was differenti from the First Who was the Roche One) and the conclusion was She had a little responsivity. She Is very worried. The doctor said to be calm and wait to do a 3rd shot.
Hi - yes different tests give different numbers, so it is not possible to directly compare the two numbers. I think the doctor's recommendation is correct. For her age a booster shot should be recommended. When is it going to be available in your area? In the US, the FDA has just authorized a third booster shot for the Pfizer vaccine. See this video here

@@NaveenAgarwalPhD here in Italy the booster is only with Pfizer's or Moderna's, even if you have been vaccinated with Astrazeneca or Johnson. But not before six months since the second shot done. So my mom can not receive her third shot until the end of january and we are not so relaxed also because the weather is getting cold.
@@federicopieroni9601 I understand. I wish you well. We are living in very uncertain times. Please stay safe and all the best to you and your Mom.

Sir, my wife took two doses of Sinopharm vaccine in January 2021 in UAE and went India. Now can she take Covishield vaccine? Please clarify... 🙏
Hello 👋, my question is this, do we have to have the vaccine every year?
Hello - honestly, it is not clear right now but things are pointing in that direction. If the virus continues to mutate, we will have the need to continue boosting antibody levels using booster shots.
Thank you 🙏
ANSWER THIS, WHY ARE DOCTORS AND NURSES WILLING TO LOOSE THEIR JOBS OVER NOT TAKING IT?
Hi - I think this is a matter of personal decision. Everyone evaluates benefit-risk differently. To some, they don't want to take this vaccine, no matter what. They would be willing to give up anything. To others, it seems unreasonable.
My perspective is that I cannot judge other people's decisions. I just hope they are making this decision based on full information, and most importantly, not based mis-information. It is best to make a decision to take or not take any vaccine in consultation with your doctor.
Best wishes and stay safe.
If you don’t have a direct comparision between COVID recovered population which took versus didn’t take vaccine regarding effectiveness and safety, you should not derive any conclusions regarding recommendations of a COVID recovered population, whether they should or not be vaccinated. The study you showed doesn’t allow the conclusions you derived from it.

I have a question. Almost 2 months ago 3 of us in our family contracted the covid virus. it took us 3 weeks to recover from the ilness. As a matter of fact, because of my asthma, I still have a lingering cough. Thankfully it is slowly going away. My question is:
"How long do we have to wait, after being sick from covid and fully recovering, to take the vaccine so that it is the most effective in producing more anti bodies?"
I think it is also important to mention that none of us has ever received a vaccination for covid. I have had mixed answers from nurses and doctors alike. Some say 2 months, some say 3 months. My doctor that I visited after a week from recovering (4 weeks total from the time of the first symptoms), told me I can get it right away. So, I am still confused. Till this day we still have not received any vaccine. We are waiting after 2 months which will be on October 25th. But I would still like an answer out of curiosity and of course, to be sure we are not taking it too early. Thank you Doctor Agarwal. I will share this video with others. Liked and subscribed.
Hi - thank you for your question. First, I am happy to hear you and your family have recovered. I have not come across any specific guidance on waiting period before getting the vaccine if you have had a prior infection. I believe it has more to do with the local policy. In many areas, there is still a shortage of vaccines. So, they may have a policy of prioritizing those who did not have the infection before.
If we were to assume that the first dose causes a "mild" infection - then the waiting period for the 2nd dose of the mRNA vaccine is about a month. That is the only thing I can think of - maybe wait a month before getting your first shot of the vaccine.
If you already caught the virus, your natural immunity is way better than the 💉 have you actually researched that? 🙄
@@Babe_804 Hi - what do you mean by "better"?
@@NaveenAgarwalPhD Take out "better" and just answer if you already had the virus, you likely have antibodies including T and C cells. Studies have shown one shot of any of the available vaccines increase antibodies. The second shot seems to do nothing further. I can find the studies if needed. What those of us who had this wretched virus want to know, is why is "super" immunity "better"? What are the chances of reinfection?
@@001LADen Thank you. As it turns out, I have found a very recent paper in the journal Science which directly compares the immune response between people who didn't have an infection before and got the vaccine, and those who had a prior infection then got the vaccine (both cases - 2 doses of mRNA). Stay tuned, I will be talking about this in a future video.
I am definitely interested in this question, not from the point of view of "better" or "super immunity", but really understanding how our immune systems are responding. Of course, each individual is different, but we can get some general understanding.
Thanks again and stay tuned.
P.S. if you do find studies that are relevant, please share. I will review them.
I think to help with "what is a good level of antibody" for the average person to have protection, they should be testing antibody levels on break through cases using the same testing protocol, along with documenting as much as possible (Ex: is the person asymptomatic, or had alot of symptoms). This should help with some kind of numbers to determine if a booster is required down the road.
Hi - great point and thank you for sharing. This is an important question and I am sure many people are studying this right now. I am keeping my eyes on it. As soon as I learn something new, I will make another video.
Thank you so much DR for the in-depth analysis. I was wondering if I have had a robust immune response to my vaccine doses (body aches, fever, swollen lymph) does that mean I would have a higher antibody count or isn't it as simple as that? Thank you so much for any help you can provide.
Hi - in general, this could be true. However, the antibody response is mounted by the immune system only after it has learned the exact type of the antigen. Or it is using the memory from an earlier infection. That is the role of the T cells who gather this information and pass on to the B cells. B cells with specific antibodies then proliferate quickly to block the progression of the pathogen (in this case the coronavirus). So the initial "robust" response with strong symptoms could be due to the initial action of the T cells and other parts of your immune system. This of course is all theoretical speculation - the best way to learn will be to do a semi-quantitative or quantitative antibody test.
@@NaveenAgarwalPhD absolutely fantastic information. Thank you so much for your insight!
Moderna & Moderna and six months later a Moderna boost. I probably have some good antibodies.
Hi - thanks for sharing, yes I would agree with you based on the data I have seen about boosters.
Would have been interesting, what the Antibody level was prior vaccination, of the people who have been infected. But this was interesting, and I am happy I got Moderna, and waiting for the booster. ( working in Health care and it's been 9 mo ) Thanks for the information
Hi - we can look at the baseline data from their clinical trial study. They measured starting antibody levels for everyone who participated in the trial. All show very low levels.
Good news for you is that the Moderna booster is going to get the emergency use authorization very soon.
Thanks for your service in healthcare. Wishing you all the best and stay safe.
Hello doctor I had 2 doses of Pfizer the first shot was ok 👍 but the 2nd shot I had really strong response I was sick for 9 days (headache, body aches., fever for 2 days , foggy brain and dizziness ) does it mean that I have high antibodies? Taking in consideration that I had the 2nd shot after 4 weeks from the first shot , unlike my friends who didn’t get a strong response on both shots !!
Hi - sorry you had such a strong response to the 2nd dose. The only way to tell if you have higher level of antibodies is to test. Antibodies are only part of the total immune response.
@@NaveenAgarwalPhD Do the vaccines create a total immune response or just a respons to the s protein?
@@001LADen by "total", I think you mean both antibodies and B&T memory cell response, right? The answer is yes. In the paper I am reviewing right now, they are showing clear data.
Thank you for your good questions. I think all of us should be asking these questions to better understand all the info that is coming at us.
@@NaveenAgarwalPhD I look forward to your upcoming videos. I stumbled on this video today. Short, to the point, explained alot in layman's terms. I still don't quite understand why I should take the vaccine when I have all the components from a natural infection. I'm not anti-vax, I just know from others who had C19, the reactions to the vax shot is not enjoyable. My own MD recommended only 1 shot. But that leaves me 1/2 vaxed. czcams.com/video/yfMlVXUgzoE/video.html
@@001LADen - The mRNA vaccines only focus on the S-protein. The breadth and depth of the immune response regarding the S protein is really good especially regarding the RBD (receptor binding domain.) it’s higher than natural infection.
Natural infection in about 80% of people will create immune response to N protein, E protein, and S protein. The downside to natural infection are the risks and not knowing if you’re in the 20% range that won’t launch an adequate response to future infections. Plus, they don’t know yet how long natural immunity lasts. I’m sure more data are coming to answer that.
Fully vaccinated ever since April2021, and in june i had an antibody test done at Quest and results were negative. So whats going on? These vaccine dont work.
Hi - yes, that is very surprising. Which vaccine did you take? If it was a 2 dose vaccine, did you complete both doses?
@@NaveenAgarwalPhD yes i said fully vaccinated. 2 doses of Moderna.
@@yautjaxenomorph9472 Hi - thank you for confirming. In some cases, the immune response may take longer to produce enough antibodies for a test to detect. Moderna antibody data shows a very large range, although the average values are very high at their peak level. I would have recommended a second test, but it has already been 6 months for you. Still, it wouldn't hurt to confirm.
What was the test detecting? Did you use T-detect or some other test? If so, those test are testing for the N-protein which you’ll only have if you’ve been naturally infected. The vaccines antibodies will only produce antibodies for the S-protein.
@@Jupiter_Crash Hi - they tested neutralizing antibodies.
hello there i suffering bell"s palsy this vaccine good for bell s palsy
You were afflicted with the palsy after the vaccine?
Hi - could you please clarify your question? Are you asking if this vaccine can have a side effect of bell's palsy?
The data is clear on vaccinations so why aren't we asking if boosters should be less a priority than Vax getting to 3rd world?!! You can't eliminate new strains from developing when the whole continent of Africa is virtually unvaccinated!
Hi - you raise a valid point. This is a policy issue. I think there is broad recognition that this is a global issue and that every one in the world should have access to a safe and effective vaccine. Having said that, each country will make policies to serve the interests of their own population. Hopefully, this will all come together at the global scale.
Do you know of a study on the severity of symptoms with reinfections without having the vaccine?
Hi - to make sure I understand correctly - are you asking about the severity of symptoms if someone gets re-infected and they haven't had the vaccine? So this would be a repeat infection after a prior infection. Correct?
I haven't seen any specific studies that target this question. I will keep this in mind and share if I come across anything.
@@NaveenAgarwalPhD Correct i feel the medical community is purposely ignoring this important question.
@@automech01 Hi - I think one way to look at this would be to review the hospitalization rates and/or ICU admissions among non-vaccinated patients who had a prior infection and now re-infected. I would expect that number to be similar to what they are reporting now where a majority of hospitalized patients are non-vaccinated. I think you are also likely to see risk factors such as age, other medical conditions etc. to play a role. Thank you for your question and sharing your thoughts!
@@automech01 No it is not. Natural infection also protects you from severe disease upon re-infection. Of course, receiving a single (or even double) dose of an mRNA vaccine on top of that can only benefit you (no downsides). Listen what a giant of vaccinology, Paul Offit, has to say on the subject...

I went to quest for an antibody test and it said greater than 20. What does this mean?

@@NaveenAgarwalPhD Sir, My covid neutralising antibody is 95% and the reference is given as above 50% is positive.
@@vvssa301 Ok thanks for the info. This is unusual but you can understand this as having antibodies in your system.

What do you think about the proposed lower dose of Moderna Inc.’s Covid-19 vaccine for boosters (50% of the dose given in the first two shots)?
Hi Cheryl - Great question! I will look into this and make another video about this topic.
Hi Cheryl - so the latest is that Moderna has submitted a data package to the FDA for authorization of the booster dose. A decision could come as soon as tomorrow (Oct 14). I will be following up on this.
Thanks Doctor. Please let me know if I had Moderna two dose vaccine, do I need to wait for Moderna boster or can mix and match?
@@sheelagandhi4496 Good news for you is that Moderna booster is now EUA authorized. I will be talking about mix and match boosters in upcoming videos.
@Naveen Agarwal, Ph.D. question what data tells for breakthrough infections?I took Moderna vaccine both shots but still caught mild covid ?
Hi - a mild cold could be a symptom of something else, not necessarily a breakthrough Covid infection. The best way to confirm would be to do another test.
In terms of data on breakthrough case, CDC has a lot of good information on this link
www.cdc.gov/coronavirus/2019-ncov/vaccines/effectiveness/why-measure-effectiveness/breakthrough-cases.html
Thank you for this video it’s very informative, however I have a concern I was hoping you might address. I am a 52 year old male and I had acute ITP in 2015 at a level of 20 when normal range should be 200 to 450 I believe. They were not sure what had caused it - may be a virus infection… It was treated with steroids prednisone 100 mg per day for 2 months , and my platelets have been proper ever since averaging around the 225 mark. In hearing about clotting and platelet issues I was extremely anxious and nervous to get a COVID vaccine however I took a leap of faith and received the Pfizer vaccine and last dose was last June . Both doses gave me very little side effects. Sore arm and a bit tired but that was it. My platelets seemed OK as I did not experience any of the symptoms that I had had in 2015 of Petechia rash etc. In hearing now that the booster shot increases antibody proteins to elevate almost double of what the first two doses gave us, should I be concerned that this high antibody protein level may trigger another low platelet situation.? Please kindly advise. Thanks. ⭐️⭐️⭐️⭐️⭐️
Hi - thanks for your question. I am not familiar with ITP, but looks like you tolerated the first two doses of the Pfizer mRNA vaccine quite well. One point I want to clarify is that the booster dose does not generate "antibody proteins". The antibodies are complex structures that basically "capture" an antigen, which could be a protein, or part of a protein structure from the virus. The booster dose from Pfizer is no different in its composition and amount of mRNA compared to the first two doses of the primary series. If you tolerated the first two doses well then it will be highly unlikely that the booster dose triggers some kind of a new response, including low platelet levels. Still, it is best to consult with your doctor. Maybe you can do a test to measure your platelets before you take the booster dose and closely monitor it afterwards. Best wishes and stay safe.
@@NaveenAgarwalPhD Thank you so much for your response. It eases my mind and makes me feel better. My doctor has advised the same. Highly unlikely would be different reaction on third dose , but I just wanted to get your take on it. Thanks so much. 🙂
@@NaveenAgarwalPhD perhaps I had worded it incorrectly, you were speaking that certain levels of a certain component was almost double and much higher than the first two doses. I was just concerned that these high levels of that certain component might trigger a platelet issue. Thank you for your feedback I appreciate it. 💉
@@joeyvee4968 Hi- thank you for your comment. I am not sure which component I mentioned, but can you remind me what you saw in the video that prompted you to think about this issue? Is it the mRNA amount in the Moderna booster? That is the only thing that comes to my mind because the Moderna booster contains only half as much mRNA as the initial first two doses. But let me know if you are thinking of something else.
@@NaveenAgarwalPhD pardon me doctor Agarwal , I am referring to the level of antibodies in the 3rd dose of Pfizer. I believe The levels are significantly higher almost double of the combined first two doses of Pfizer. I was concerned that these much high antibodies can trigger platelet reduction. Of course I don’t fully understand the dynamics involved , hence why I seek clarity. I’m sorry if my terms are not on point. Thank you.
I done antibody test the results 24
I take 2 doses of pfyzer and i done the test after 7 months
Had Covid in April, checked antibody level in September and it was 58. Got my first dose of Moderna in October, had my antibodies rechecked last week and they were at 2,500. My question is, do I need a second dose or can I wait?
Hi - thank you for the question. You need to take the second dose as prescribed to be considered fully vaccinated. Can you share why you are considering to wait?
@@NaveenAgarwalPhD Thought if antibodies were high, it would be overkill.
@@michelemclaughlin4474 Hi - that is an interesting point. I have not heard this. I am not sure what, if any, the harmful effect would be.
@@NaveenAgarwalPhD Thanks for the reply. Yes, I’m torn on whether or not to go. I’m suppose to get my second dose Tuesday, but not sure I want to just yet. People should be considered fully immunized with one dose of an MRNA vaccine after they’ve had Covid, but that doesn’t seem to be the case and I don’t want to only be considered partially vaccinated.🤦🏻♀️
@@michelemclaughlin4474 Hi - yes that is a good point. But right now, you have to complete both doses for the primary vaccine series to be considered complete. What does your doctor say?

Right lol
My seafarer husband Is being required by his company to get vaccinated, he will comply even if he doesn't want to for both of us believed the vaccines can do no good to our bodies. My question is..can he somehow expel or remove the vaccine in his body the natural way?
Hi - are you asking if somehow the body can expel all of the vaccine without affecting the immune system? I am not aware that this can be possible. Do you feel this way about this specific vaccine (covid19) or do you hold this view for all vaccines that they "can do no good to our bodies"?
@@NaveenAgarwalPhD how long the vaccine stays in our body?? . what to do to detox those vaccine ?
@@aye1556 Please read this description of how vaccines work on CDCs page www.cdc.gov/coronavirus/2019-ncov/vaccines/different-vaccines/how-they-work.html
@@aye1556 - the vaccine components are broken down within 2 days of entering your deltoid muscle, There is no need to “detox.”
I have the SARS-CoV-2 Semi-Quant Total Ab test 8/31/21. Result was positive 68.6 The LabCorp report doesn't explain what that number indicates. My MD also cannot explain it other than to say it indicates I had COVID-19 and I should get at least on shot of a vaccine. Perhaps I'm missing the point on why super immunity is better? Antibodies wane after infection and after vaccination. Shouldn't memory B and T cells still exist?
Hi - These are two different ways our immune system fights an infection. In the end, you do need neutralizing antibodies that will block the pathway through which the virus attaches to cell receptors and continues to multiply. Commercially available antibody tests give the total number of antibodies, and not specifically neutralizing antibodies. The two are correlated, meaning if the total amount is high, then the neutralizing antibody amount is also high. But we can't be sure of how much. Memory cells will create a memory, but neutralizing antibody needs to be available to block the transmission.
@@NaveenAgarwalPhD Thx you for the quick reply. How long do neutralizing antibodies last? The whole C19 booster plan is confusing when other viruses, such as mumps, measles, don't require a booster.
@@001LADen You are welcome. Yes, the level of neutralizing antibody does go down over time. See this video I just released where I discuss the data on Pfizer vaccine booster shot
czcams.com/video/RXM1reL7UIw/video.html
I agree, the C19 booster plan is confusing - it is needed because we still have very high rates of transmission in certain areas and many people are still at risk, even those who have already received 2-doses of this vaccine.
I believe I had that same test. Well, on the test results mine was called SARS-CoV-2 Spike Antibody test. Maybe mine was slightly different than yours. I had mine drawn on 10/4/21 which was almost exactly a year from when I initially had symptoms. My level was 654. I wish there was more info on these different Covid antibody tests. There are several types and I don't know how they correlate and why one test might be ordered over another.
@@Joe_Friday Hi - the "spike antibody test" name means that it can detect antibodies that bind to the spike protein of the virus. Only some of these may act as neutralizing antibodies. It is good to see your test result showed a pretty good level (again, compare it to the range of the test to be sure) after 1 year.
What kind of other questions do you have about antibody tests? I will be happy to look into it and discuss in future videos.
Why would you want a booster shot if you've had covid, why would you want your antibodies boosted if you aren't planning on catching it again?
Hi - this is a very good question. It depends on your individual situation. Generally, the level of antibody drops over time. There may be some individuals who may be at a higher risk because of this - either their antibody levels were low to begin with, or they have dropped to a very low level. That is why it is a very individual decision that should be taken after consulting with your doctor. What the FDA is doing is creating a lot of flexibility for the doctors by clearing the regulatory barriers. Hope this helps.
@@NaveenAgarwalPhD So are you saying that having had covid, some people may get it again and that's the reason for a booster, a just incase measure?
@@joyfuljoyful6598 Yes that is correct. Re-infection is always possible even for those who took the vaccine more than 6 months ago. There is general concern that the immunity levels in the population are dropping and with new variants emerging fast, we have to worry about protection against serious illness. Especially those who are particularly vulnerable from a health point of view.
@@NaveenAgarwalPhDSpike proteins shed why would you want a covid protein in your body when it sheds it spreads?
@@NaveenAgarwalPhD One would think that promoting strengthening your immunity with other natural alternatives would be a far safer alternative for those who are immuno suppressed or with other issues that may course adverse reactions with the vaccine. Surely promoting the use of Vit D3, K2, Zinc, Magnesium and vitamin C or even Manuka honey, is just as beneficial as the vaccine. I wouldn't want a protein running rampant in my body.
effective for like 6 months max
Hi - yes, there is a concern that the level of protection is decreasing after about 6 months. That is why we are now talking about booster shots.
Seems the only guaranteed immunity is for the Drug companies.
So technical...only geniuses can understand this... How bout me.. I can only understand laymens terms.

So your answer is still hanging, no certainty. Same old same old.
Hi - only two things are certain in life - death and taxes! We have to make decisions in light of uncertainty. And every individual is different. Their risk tolerance is different. They make decisions differently. Would you agree?
So sir please tell what antibodies numbers are highest and lowest then in order to guide people on the decision to booster or not. How are we sure the booster won't affect natural immunity? Will it be better or will it lessen at the least?
@@raymundpadilla3619 The best guidance will come from your doctor at an individual level. There is currently no generally accepted "level" of antibodies that is considered to be required as a minimum for maintaining your level of protection. Also, note that antibodies are only one part of the total immune response.
So the short answer is - it depends on your own individual situation. What we have is a number of options available to give this flexibility in decision making.
To your question about effect on "natural immunity", it has been shown that a booster dose actually stimulates the immune response. Overall risk profile is no different than the primary series and there are no new safety risks.
Again, let me emphasize - this does not mean it is "zero risk". Risk will also depend on the individual level.
Hope this helps.
Thank you for your response sir.
