TWiV 1121: SARS-CoV2 still didn't come from a lab
VloĹžit
- Äas pĹidĂĄn 7. 06. 2024
- TWiV rebuts a recent opinion piece which falsely claims that the COVID-19 pandemic began in a lab (it began in Nature), followed by a discussion of Paride bacteriophage, which has the unsual property of being able to kill dormant, antibiotic-tolerant cells by direct lytic replication.

Thanks Les
Thankyou
From Africa Zambia, I recently started following microbetv ,this has been so excitingđđđđđ
This presentation is entirely one-sided with one âchoirâ echoing the natural spillover hypothesis. Why not bring Alina Chan and others into a discussion and debate on the points in question? I agree with Chan that the probability is higher for a lab incident than for a zoonotic. Vince interviewed Daszak years ago about research undertaken on SARS-CoV. That interview for me raised many questions about what EcoHealth, Baric, and WIV were doing-especially given such research at WIV being conducted at BSL-2 labs. I agree further with former CDC Director Redfield who also opines the probability for a lab leak is higher than for a natural spillover. Chinese authorities have obfuscated from the outset and have blocked all efforts to have a proper forensic investigation such as R. Ebright argued is essential to settle the question of origins. Have a proper debate and, as some have suggested, write your counter to Chanâs opinion piece and publish it.
Why? Because that would not help further their narrative.
Conspiracy monger weighs in
You do realize that since the earlier SARS spillover, there was a collective effort to gather sample from animals in the area for the next pandemic. So where did you expect that work to take place, if not in WIV?
Why have experts debate a lady who wrote a whole book of BS?
These are good old friends, there is no space for proper discussion or evidence here.
In evaluating scenarios involving engineered sites, itâs crucial to treat exceptions as just that-EXCEPTIONS not the norm. We must integrate probability into our analyses, maintaining a discerning approach to what is likely versus what is merely possible.
Among the four main lineages of betacoronaviruses (A, B, C, and D):
1) Lineage B betacoronaviruses, which include SARS-CoV and SARS-CoV-2, generally do not feature a furin cleavage site. SARS-CoV-2 is an EXCEPTION within this group, possessing a furin cleavage site at the S1/S2 boundary in its spike protein, which is considered unusual for this lineage and is a significant factor in its enhanced transmissibility compared to other coronaviruses like SARS-CoV.
2) Lineage A betacoronaviruses (like HCoV-OC43 and HCoV-HKU1) also LACK a furin cleavage site in their spike proteins.
3) Lineage C and D betacoronaviruses, less studied compared to lineages A and B, have NOT typically been identified with prominent furin cleavage sites, although specific studies may provide more detailed insights as new viruses are discovered and characterized within these groups.
Overall, the presence of furin cleavage sites is NOT common across all betacoronaviruses and is seen as a notable feature primarily in SARS-CoV-2 within the context of the current pandemic. This feature enhances the ability of the virus to infect human cells, making it a significant target for gain of function, and that is why it was proposed in the grant application.
The FCS, while interesting from a research viewpoint, is something of a red herring. It's certainly not the smoking gun that the man-made/lab-leak conspiracists think it is.
Jolene, no sabĂa que hablabas tan bien el espaĂąol Me gustĂł muchĂsimo tu vĂdeo. Muchas gracias!

Definitely worth viewing and listening tođ
Remember when the mRNA covid vaccine was 100% safe and 100% effective đ
lol 100 % safe and effective ? You make that lie up . With such low integrity you must be an antivaxer
Can't you see it?
DNA synthesis was used to express an RNA protein; that is, RNA to DNA to express a cancer resistant property, or so they thought.
From a logical and legal perspective, the effort in public to discredit lab leak while foia information shows internal concern and the mountains of circumstantial evidence raises legitimate question. I'll be curious how this is squared. I suspect there is a lot of confusion caused by semantics and many details are used over confidently. A debate would be most interesting. Not an endless series of one sided panels.
Evidence for lab leak ? Yet to see one , there is none so far . Please present .
Were there "mountains" of evidence the concerns might be legitimate. Repetitive speculation is not even circumstantial "evidence." And no, data-driven conclusions cannot be decided by a debate.
Why cling to a conclusion of a lab origin theory that is only based upon suspicions. At 58.02, the experts discussed this issue.
Many believe in a lab origin of HIV/ AIDS. Some believe that the Devil pops up from underground. I believe that the moon is made of blue cheese.
The only thing a debate proves is who is the better debater.
@@Logotic true . Also when did debates become part of science ? Debate is valid when people are discussing opinions . Science is fact based . Discuss studies and facts .

Would you be willing to pen an op-ed to submit to the NYT rebutting Chan's claims? I hope they would publish it.
Or maybe just interview the author who wrote the article and talk about what you agree and disagree about?
Hopefully they would ask them to not ignore Weissman (2024) showing ascertainment bias in early case data or new genomes from Lv et al (2024) showing a single point of emergence rather than multiple spillover is more likely. Not to mention Jesse Bloom's papers showing the market samples don't show a link between susceptible animals and SARS-COV-2 genetic material.
Don't think a Dunning Kruger conspiracist fraud like her deserves a rebuttal.
@@riok6234 She's not a virologist.
@@alohaworld and no one on the twice team is a public health specialist focussed on tracing viruses.
The truth floats-thx Rich. Iâm quoting you.
These RNA viruses have a shotgun approach to evolution, producing many particles per infected cell that may have incomplete or defective genomes after the cell that gave rise to them lyses, but as long as a few other cells get infected by these released virions, before many rounds of infection, the host is releasing billions of virions, some of which can infect other hosts. There is a good chance that variants may be produced with every host infected. By chance some variants have some selective advantage (i.e. there is a natural Gain of Function), and may produce new waves of infection, having variations from the original antigens on the viral surface, escaping the immunity prior variants have conferred on previous infections in the new hosts.
Chasing the origin for SARS-CoV2 is futile, since there is no breadcrumb trail to follow, the intermediate virus genomes have long mutated away.
What is not often repeated is that throughout the world, there are individual people who have cross reacting antisera to SARS-CoV2, who showed no symptoms right from the beginning of the pandemic at the end of 2019. The virus origin may have been circulating in the human population, certainly in Italy before September 2019, where stored blood showed antibodies to SARS-CoV2 have been detected.
Perhaps some unknown traveller was coinfected with a similar coronavirus in the Wuhan area, resulting in a natural chimeric genome that became the origin of COVID-19. We shall never know.
Thank you so much! I was waiting for a rebuttal.
Thank you for walking through the article and addressing each point w/hard facts incl historicals re research, methods, sources, milestones, socio-political & stats. The links & time stamps are also very-much appreciated!
Which facts? I saw no single fact that proved anything one way or the other.
I did see a lot of informed opinions.
I have no doubt that everyone here is well educated and informed.
But I also know that there were many well educated people who make incorrect Analysis the whole pandemic.
The initial point seems to be that the closest thing found to it in nature is wildly different, then say, therefore not engineered. Exact opposite seems to be the case

"The truth floats, unfortunately it takes a long time to get to the surface."
That's brilliant, thank you!
And bullshit also floats. Human history has always been one long bloody contest between which of these will prevail.
Unfortunately doctors, in many countries like Canada, ignore what patients are telling them. My neighbour worked in a hospital and had a terrible lung infection for 3 months before COVID was announced. Not one doctor looked any further.
I love your show by the way. It helps me sleep at night. â¤ď¸
Exactly, the sequences aren't there. Scientific integrity is unshakable.
Can we say that lab leak is completely wrong? Unless the research proves 100%, then all other theories would be âless likely statisticallyâ in your opinion?
Chan did not submit this contention as a scientific paper. It would not likely have passed peer review. Key papers are ignored or omitted. (see TWIV 876).
This is a good example of cherry picking, straw man and exclusion of pertinent research. Publish it?
It seems the TWIV team are heavily invested in their own narrative. Why cannot this be dicussed impartially in a bipartisan manner? Is there that much vested self-interest involved?
Bipartisan lol. both parties agree you should sign your childrens lives over to the government for their next war
I was just thinking how nice would it be to have an episode that references past episodes about and comprehensively addresses the lab leak theory. I have many friends whom are sure that SARS-CoV2 originated in a lab and they all have short attention spans so they would be unwilling to listen to multiple episodes of TWiV but I might perhaps be able to get them to listen to one episode, this will be that episode I refer to. Thank You TWiV team this episode especially beneficial to the fight against misinformation!
There is good one ( not TWIV) that has Eddie , Michael Worobey and Kirsten , 2.5 hours . That one is very scientific and totally worth it .
@@Sceince007 thanks I appreciate it, I wonder if anyone has done a version of this debunking for 5 yr olds. That would definitely reach misinformed folks a lot easier.
â@@lukeplant7077 đđđ Thanks for that!
Vince , perhaps you can educate the ideological polemicists in Congress?
I'm so glad you did this episode. I'll post it on Twitter, although in the past I actually received a warning for sharing a previous episode where this was discussed. Unfortunately people aren't interested in the truth; it's not sensational enough. It's easier to place blame.
A warning? Is Twitter censoring critical coverage of lab leak stuff now?
Some people may not be interested in your version of truth. I understand why lab researchers who depend on grants (and job security) would have a difficult time with the idea of a lab leak. It's just too uncomfortable to think something so horrific as a lab leak actually happening. But, juicing up already dangerous viruses to make them more likely to harm humans, and harm them quickly, is irresponsible and unacceptable in today's world. A moratorium is needed now to stop doing "gain of function" research.
Thank you đ
This "panel" is self-congratulatory coping from another level lolđ đ
RACCOON DOGS AGAIN????
Wow.
Hmmmmm .......lets see - raccoon dogs are known to have been susceptible to a bat SARS corona virus & to be a suitable intermediary vector for human infection some 20 years ago. What are the chances that it could happen again with another bat corona virus? ..........Really really high actually..... who'd have thought that the basic biology of the virus, the bat, the raccoon dog and the human hasn't massively changed in 20 years.
No clue what "...self-congratulatory coping from another level..." means in proper English .......I'm guessing that's derogatory. What you observed was "confidence" - because they are all highly educated & qualified in their chosen fields and know exactly what they're talking about.
Do you have an expertise other than trolling?
Fact is..there are Chinese run biolabs being found in California. .
...what does this team have to say about this ??
United front run
I heard the Chinese have tampered with our coca cola supplies
Thank you for these acts of love
Honestly, this sounds like something an AI may have written, but I'm down with it...
TWiV is going to the mat for their friends. So, it is an act of love but what is not.. is an act of good science unfortunately.
Interesting how conspiracy theorists never question the people they're getting their 'information' from. Wildlife trade is a billion dollar set of industries, with a strong interest in not being at fault for the recent and future pandemics. Anyone else wondering who is funding Chan for her article?
It's funny you say that when Daszak is funding people to say otherwise
Confirmation bias + ignorance ......they go with whatever fits their own preconceived ideas & are not smart enough to see the conspiracy nonsense for what it is.
Alina Chan co-authored a book (with Matt Ridley I think?) which is basically a long-winded version of the NYT article. Clearly, book sales are slowing down now the AVs have realised it has too many words & not enough pictures.
Quite surprisingly, the book is in the "non fiction" section if you're interested.
Yeah, her funding at Broad comes from Big Wildlife Trade. She's obviously a conspiracy theorist.
Anyone wonder who is funding dazcek?
@@brendanmay9585 EcoHealth was a rainmaker for careers!
Why did the Wuhan Institute of Virology remove their research papers from their web site?
Um. China.
They were done with those and the data . However since they had tried to publish it it never went away. Also the magazines allowed the data to be published. No smoking gun there .
@@Sceince007 They were done with those and the data ?
@@thedrunkenchefs4577 they were done with those genomes and the data , thatâs why they were removed . Like man do . This was discussed in detail in one of the TWIV episodes .

Jolene is a nice addition to the team.
I suspect that Jolene might be the power behind the throne...
You should keep producing quality scientific discussions and reinforce the spillover hypothesis to keep everyone informed. Important information needs constant reminders. We can deal with the distraction caused by the fringe.
Quality would be specifically discussing with a proponent of the lab leak theory. 6 vs. 0 is not particularly useful.
@@brendanmay9585not if you are going to bring in substandard conspirators. TWIV got it right by bringing only real scientists. 43:02
â@@brendanmay9585 Sure. And in the interests of providing quality education to our kids, proponents of Intelligent Design should be invited into the classroom to provide a counterpoint whenever evolution is taught school. That'd be much more useful than simply learning about evolution from someone who knows what they're talking about.
@@nuynobi again. You are just making a poor argument.
With intelligent design vs evolution the debate has been settled.
In this case there is no conclusive evidence either way, thus a debate is absolutely valid.
@@brendanmay9585 even after she has already pr Ben herself to be a liar ? What will a discussion with a proven liar do ? For you it will be gibberish as you have already admitted you do not understand evidence .
Wow. Fascinating to see this groups firm opinion... despite evidence to the contrary at several levels. The group psychology is the most interesting aspect of this discussion.Where is the critical thinking and exploring the many aspects of gray? Where is the interest in the questions and consideration rather than laughing at or demeaning peoples comments as 'conspiracy' and denial. No dialogue or debate... Given we are at a time where so much research is intentionally hidden from view or even fabricated, yet there is no scepticism on the data despite the extent of misinformation and censorship. Which is understandable given the implications of the lab leak and cascade of harms we are still suffering.
how many virions can dance on the head fo a pin?
This group represents >99% of relevantly qualified scientists in the opinions & facts discussed here. All the dialogue has already been done & debate is not how science works.....you can debate ideas & opinions - science is settled by experiments, which can be repeated independantly to achieve the same conclusions.
@@howilearned2stopworrying508
Dance? none
Theoretically one could fit between 200,000,000 and 500,000,000 on the head of a pin approx 2mm in diameter.
But if you want a more realistic example - go for a swim at your nearest beach, take an empty 1ltr bottle with you & fill it from the ocean.That litre of seawater will contain close to 10,000,000,000 virions.
An intelligence test most people failed.
These people are virologists. I would believe them before people who have not extensively studied and have worked in the lab with viruses.
Interesting that the arguments against lab leak contradict each other.
1) we only found it BECAUSE there were good labs, it was probably elsewhere before it got to the market.
2) finding two different variants at the market means it must have crossed ovee in the market.
Hmm so which one is it?
Dumbo two different market for each lab leak , not the same . Your designation is hilarious. Now that you got yourself in a bind care to explain why each variant chose to ignore more crowded areas in Wuhan and went straight fur market each time ?
What makes it contradictory? Your desire to make it so? If a hunter caught an early crossover in the middle of a cave, in a countryside as backwards as China, the chance of observing it and catching it is slight. Look at the AIDS example. It originated in Africa, decades ago. First observed cases of identifiable AIDS was in LA.
@@AlbertMark-nb9zo but that is exactly my point.
The argument thatnitbmust be from nature seems to stem from the argument that huanan market was the crossover location.
@@brendanmay9585 - my point is that your original post against lab leak contained contradictory arguments wasn't a proper assessment. There were various independent factors.
The wet market is a natural focusing point of where a natural spillover is going to more likely happen because it concentrates interactions of natural species in unsanitary conditions with people.
If the argument is that it arose in a lab, to the wet market, that seems to unlikely, given the characteristics of the virus. And the history of the research being done. The wet market is great for concentrating what's maybe there, but the fact that you would've needed over a thousand mutations to get from the closest known virus at the time shows that it was highly unlikely as an incubator in the time period. One of the TWIV's has scientists looking at various other natural Coronovirus'. These have aspects much closer to COVID19. It's things like that, that point more to a natural source. It took around 10 years to source a cave that contained all the elements to produce SARs. And they still didn't find a definitive ancestor.

@@PK779ablelol without evidence though . Also you forgot to mention the other intelligence agencies which do not . At least you must have put together something in your head to counter the overwhelming evidence for zoonotic origin . Can I ask you specific questions ?
How do you explain two lab leaks lineage A and lineage B ?
I have more than dozen questions .
@@PK779able yeah like how they hadcredible inteligence about Iraqi WMDs. they definitely wouldnt lie to make their bosses happy
It's guessed some here also appreciate the efforts to force vaccine escape.
You mean the misinformation from the WHO that literally says we don not have enough evidence to rule anything out?
Why refer to Pekar et al in support of multiple spillovers when new genomes published in Lv et al (2024) show intermediate genomes and spread before the A-B split? These lineages were only two mutations apart anyway so it was always questionable that they reflected separate spillover events. A new PubPeer comment also shows Pekar compared likelihoods of *different outcomes* for N=1 and N=2, with N=2 given a bigger target. When corrected single spillover is more likely.
They also appear unaware of Weissman (2024) showing ascertainment bias in early case data or Bloom (2024) showing the environmental samples show other animal CoVS linked to susceptible animals but not SARS-COV-2?
Ultimately WHO is still calling for data on both the animal trade and Wuhan labs so they should support that.
Not true . The papers used rejected samples . Where is Lv et al published ? Are they not using genomes rejected by Worobey as group for incompetence samples and 5 other reasons ?
Also Pekar mistake was caught before publication and fixed and it did not change the end result or papers significance so stop lying . Your đdesperation os way too obvious

@@mpennipep I am not aware of any evidence for a conspiracy. Care to mention what that evidence is?
As in all good conspiracies a few strands of truth, which alone are of little relevance or consequence, can be woven with a fabric of un-truths to create an ever lasting 'cloak of righteousness'. Some people use this to cloak their own 'agendas'. Sadly, I doubt this one will ever go away, no matter what evidence comes to light in the future.
Virologists have become hyper-partisan to a very uncomfortable hypothesis that they have trouble discussing. Most of the world knows what's most likely to what your field has become too biased to see. This bias needs to be addressed going forward because it makes the field more dangerous.

@@shannond.4129 It's almost like you have gotten caught up in their BS. *Holds hand & explains basic logic *
What the natural zoonosis side needs to have evidence are infected animals with the precursor and a path to Wuhan that makes more sense than a virus hunt or strong evidence the infection was present somewhere pre-Wuhan.
Minus that....Everything that we have that's "evidence" for zoonotic origins is not unexpected in the presence of a lab leak and we can't say the same the other way.
They sounded pretty comfortable to me. Maybe a little exasperated having to keep doing it. Much like me reading some of the clown comments on display in the chat
â@@shannond.4129Jesse Bloom, Etienne Decroly, David Relman, James Le Duc David Fisman, David Baltimore, David Heymann consider its unclear either way. WHO is still calling for data on both the animal trade and Wuhan labs.

@@Sceince007 in a way he's right - but for all the wrong reasons.....viruses evolve - mutation occurs at the genetic level.
......I still think he's an ignorant conspiracy troll though
The differences between the two lineages (A and B) were miniscule. The fact that there were two slightly different versions of the virus circulating in the early days isn't the slam dunk against the lab leak hypothesis they think it is.
For RNA viruses, âmutateâ is not the proper term, thatâs what they mean.
If anyone has a serious counter-argument to the rebutal made by the twiv panel, you can post them here. Maybe there are some valid counter-arguments to a few of the points they made. I'm sure the twiv team would be open to hearing them. But for now, the twiv arguments are sound and convincing.

How did Alan miss calling this episode "This little virus came from market"
In the comments you'll find a bunch of people who can't explain virology basics, for example virus replication, how cleaving works, bsl, mutations, and genetics; all things you need to be able to speak on this topic. Somehow they have the hubris to think there are experts outside of virology, microbiology, immunology that are more informed without any demonstration of expertise. If you are one of them, there is a free virology course on this channel, you can spend some time yourself to get some basics before parroting some politician or failed scientist like Chan
Epidemiology 101: Examine area you first find the outbreak for likely spillover spots & then examine sequence and see if you find a link. We note some of the closest ancestors were worked on at the lab.
Almost right away we knew two things.... the labs were a very likely source of the outbreak and the field had issues being objective and were not going to be much help due to they labeled the most likely spot a crazy conspiracy.

Can someone knowledgeable speak to the lack of progenitor variants? Maybe give another example of an airborne virus without evolutionary history. The lab origin sounds like the most likely scenario to me by overwhelming circumstantial evidence. Had to do a double take on the date of this vid. Kinda shocked really. Listening now.
Good point. New genomes were published this year by Lv et al which suggest a single point of emergence with lineage A coming first. The panelists here seem to have overlooked it.
Yeah. Lab Origin is hard to wrap my head around as if it is true it would have dark implications. Those implications being that "covering it up" would be obstructing the scientific force of 8 billion people from whatever data was gleaned during the work in the lab. Then there is the question of genomic patens. Maybe a question would be is if it was a lab leak, what would that look like?

This was a great rebuttal but I think whatâs needed is a succinct piece laying out the case for a natural market origin that can be submitted to the NYT. Five key points in descending order of importance, perhaps drawing from Worobeyâs article. Not a rebuttal as the main points (although can be used to support) but the strongest points in favor.
Why are the panelists still referring to Pekar et al in support of multiple spillovers when new genomes published in Lv et al (2024) show intermediate genomes and spread before the A-B split? These lineages were only two mutations apart anyway so it was always questionable that they reflected separate spillover events. A new PubPeer comment also shows Pekar compared likelihoods of *different outcomes* for N=1 and N=2, with N=2 given a bigger target. When corrected single spillover is more likely.
They also appear unaware of Weissman (2024) showing ascertainment bias in early case data or Bloom (2024) showing the environmental samples show other animal CoVS linked to susceptible animals but not SARS-COV-2?
Ultimately WHO is still calling for data on both the animal trade and Wuhan labs so they should support that.
I donât disagree with you. I did not know about the more recent data regarding the lineages. I am persuaded by the panelists based on my perception of their integrity and expertise but Iâm open to the lab leak theory. Thereâs no conclusive smoking gun yet on either side, which to me would need to be a credible whistle blower on the lab leak side or a definitive intermediate host or definitive animal-to-human jump on the natural origin side.
Great lesson in critical thinking guys. Thank you

@@PK779able I assume this was meant for someone else.
Consider it may have not been "made in a lab" but collected from a natural reservoir and worked on a lab. Hence the "origin" argument. Just too many credible scientists and too much paperwork evidence that there was a plan that was included in a grant proposal that was denied. Ill be interested in how this information is discussed. Again, it would be facinating to see a debate among equally experienced and knowledgeable scientists.
The grant proposal was well debunked as being related on a genetic level but it shows a willingness to go there. To go someplace deemed not acceptable. The fact that there are laws prohibiting certain research does not mean its not possible and working offshore opens the possibility to keep it out of sight (especially in collaboration with PRC controlled ppl). At this point, its a mystery of logic; means, motive, opportunity. And given what we know it seem far from implausible.

Before this episode, I was convinced of the virus not being lab born. But the more "evidence" you try to bring to the listeners attention, the more I doubt it.
For example, why could a lab born virus not be able to mutate so fast that you have multiple strains (after who knows how long?) next to each other, but a wild born one can?
And why is the locality any indicator? Only people who were close to the market at that time must have had exposure? 1. The virus is transmissible AF, so it could have traveled with people. 2. We don't know how long it already lingered before people even got aware of it so it could have traveled in hosts to wherever at that point. 3. To this day we have seen many many people who are completely asymptomatic so those who didn't even feel sick could have carried the virus to who knows where.
Plus, is it really hard to believe that in a country which shuts itself off to the outside as much as possible and suppresses its citizens, a revelation like this could have maintained concealed? Then the scientists would not even had to lie, they simply did not communicate their findings/work. In a time, where a Mr. P. can convince hundreds of millions that a war against country U. is not a war but some kind of minuscule mission, it seems completely plausible to me.
You probably have a big urge to debunk incorrect "science" but please, stop it with this one at least. You discussed it ad nauseam and you only ever give those people a bigger stage than they would (deserve) otherwise. So do yourselves and us a favour and leave it at that. It's like the quote "For those who believe, no proof is necessary, for those who don't believe, no proof is possible." Ye ye, science is not a believe, but in the end people do "believe" science or they don't, same with conspiracies.
Wombat you have managed to tel us that you are clueless . Your post is hilarious and makes zero Dominic sense an DC many things posted are contrary to facts
If the virus is contagious AF, as you put it, why did it wait until it got to the market to effect other people and create clusters of cases. Instead of family units, then schools, and other gathering places. A Korean christian spread it like wildfire just attending church, early in the pandemic.
Thankyou for this.

You guys are in your own echo chamber of denial. It's fascinating to watch.

That comment is entirely meaningless......even more so without a definition of "freedom".
If you think "God" is laughing at you that's just another affirmation of your paranoid delusional schizophrenia. Spoiler alert: "God" doesn't exist - it's just an idea - a metaphorical father figure created in order to teach the ignorant & uneducated how to behave in civilised society
I wonder if Alina Chan harbors some anti-Chinese sentiment because of her origins from Singapore (through Canada) and this fuels her narrative.
Does this apply to the Dept of Energy Z-Division scientists at LLNL who favor lab origin too?
While that is a possibility, Its more likely that Chan's background in the area of gene editing is fueling her confirmation bias.
IT CAME FROM A LAB , HOW DENSE ARE PEOPLE
You should also provide evidence so we "dense" people can read it
like Stephen King's The Stand? Don't fear the reaper, get back to the office!
@@user-br6px6ok9x Plenty of evidence has been provided and it's won the majority view of the world. A lot is listed in Chan's piece. An uncomfortable hypothesis puts people in denial and causes them to dismiss evidence with bad reasoning.
Youâre likely right but your name calling isnât an argument and is not helpful at all.
oh yes, when has the majority of people without any scientific background ever held a completely false opinion? *sigh* seriously, all the darned time and youâve all latched on to 5 confused scientists with an axe to grind or book to sell and decide all the professionals who have been doing this work for years must be lying for no good reason đ
I am unconvinced by this discussion. (I bet this group thinks the vaccine is great. Am I right?)
Saved millions of lives, so yeah.

Vaccine did not clearly save many lives at all, but excess deaths are indisputable.
Yes, it came from Mother Nature's ''lab'', courtesy of thousands of years of evolution! laughing emoji!
Man helped through the $70 billion wild animal trade bringing in disease carrying live wildlife into the Wuhan animal market known to host sarbecoviruses. Nature and the illegal animal trade works at BSL level zero.
The amount and variety of virus in nature dwarfs anything in labs.
Title should be âLab leak proffered evidence not sufficiently supported. We still donât know the origin.â Also it could be lab origin and yet not engineered. Bats brought in for study, or an employee who investigates caves could have theoretically brought the virus to the lab. I think the only honest answer is: âWe just donât know.â
Did you even bother to listen to this video?
Why do you think the epicentre for both early lineages was the market - some 20-25km away from the lab?
Why do you think None of the early cases were at or around the WIV.
You're almost right, the honest answer is "We just don't know, but all the evidence suggests a natural spillover event in/around Huanan seafood Market is the most likely explanation, whereas the alleged lab leak theory has no plausability or evidennce behind it".
WHO's position is all hypotheses remain on the table.
â@@fifthoarsmanoftheacropolis4173Weissman (2024) shows that the early case data is affected by ascertainment bias so is not informative unfortunately. As David Relman said it's "hopelessly impoverished". Also, new genomes published by Lv et al (2024) indicates a single point of emergence not multiple spillovers and A came first. As all the market cases were lineage B that suggests the market cases were not the primary cases. WHO has called for data on both the animal trade and Wuhan labs and considers all hypotheses remain on the table.
The problem came from a lab, and so did the solution, Omicron.
Omicron is believed to have been an immune-pressure escape mutation, since there were so many nonsynonymous mutations.
@@gribbler1695 sounds like modern medicine is flawed, pumping people with deep pockets full of engineered antibodies so they can stick around for 1 mroe day as an incubator for more variants. And don't tell them to wear a mask when they jet off on a vacation, either. Bill Hamilton was right
Once again Iâm enormously grateful for your presentation of the actual data and science as opposed to speculation. Iâll be copying a link to this episode on social media. Blessings
I've felt obliged to add Alina Chan to my Expert 1d10t$ list, now totalling 65.
A number of recent papers highlight how uncertain the origins are though. Michael Weissman has shown proximity ascertainment bias in early case data. Note all market cases were lineage B but lineage A likely arose first in light of new data published by Lv et al (2024). WH0 are still calling for data on both the animal trade and Wuhan labs. It's not a clear cut issue by any means.

But if SARS-CoV-2 taught it anything it should have been that educated opinions are better than nothing when you need to make decisions quickly, but they are often wrong.
