Analysis Proves SARS-CoV-2 Lab Origin

In this interview, Dr. Steven Quay — one of many most-cited scientists on the planet1 — discusses his Bayesian evaluation,2 revealed January 29, 2021, which concludes past a doubt that SARS-CoV-2 is laboratory derived. Quay is an M.D. with a Ph.D. in chemistry. You can be taught extra about Dr. Quay on his website.

He did his medical residency at Mass General at Harvard Hospital and his postdoctoral work at MIT with a Noble laureate. He holds 87 patents in 22 fields of drugs, together with the gadolinium used with MRI imaging.

During his profession, Quay revealed 360 papers, which have been cited over 10,000 occasions. His COVID origin paper, nonetheless, has already been downloaded 170,000 occasions. Bayesian evaluation,3 or Bayesian inference, is a statistical software used to reply questions on unknown parameters through the use of chance distributions for observable information.

Quay’s extremely conservatively-skewed evaluation reveals there’s solely a 0.2% probability that this virus got here from nature, and a 99.8% chance that it got here from a lab. His 140-page paper will be downloaded from zenodo.org4 for individuals who wish to dive into the nitty gritty of this statistical evaluation. He offered these information to House Representatives throughout a June 26, 2021, subcommittee on the coronavirus disaster assembly.5

Instead of utilizing the noticed statistics of the information he gathered, he radically lowered the chance to 1 in 20. When one combines all of the statistical anomalies from the 26 completely different information factors he collected, the true probability of the virus coming from nature is lower than 1 in all of the atoms of the universe — 1080 — which is a really, very giant quantity, making it nearly inconceivable.

SARS-CoV-2 Has a Protein Sequence Found in Bee Venom Toxin

As early as January 2020, Quay knew SARS-CoV-2 might be problematic. 

“Nobody was paying any attention because there was no need to at that point,” he says. “I noticed this virus popping out of China. I seemed on the sequence of it and I keep in mind telling my spouse, ‘I do know what this factor goes to do in cells,’ as a result of for 5 years at Stanford, I used to be finding out and was the world skilled on the toxin melittin, which is a bee venom toxin, the factor that hurts if you get a bee venom …

This melittin, this toxin in bee venom, has the identical sequence that SARS-CoV-2 had … I run a public firm, so I went to the board a pair weeks later and stated, ‘Look, I feel we are able to provide you with some therapeutics and a few concepts round this.’ We truly are in medical trials with some merchandise for therapeutics towards SARS-CoV-2.

Then I began listening to some actually loopy public well being advisories round masks, social distancing and issues, so I ended up writing a bit of e-book that was a No. 1 greatest vendor for a couple of weeks referred to as ‘Stay Safe: [A Physician’s Guide to Survive Coronavirus,]’ on Amazon. That took me by means of the summer time. Then I began going again to one thing. I used to be very involved about what I noticed as properties of this virus that had by no means been seen earlier than.

It’s now public data that the federal government recognized one in every of my papers, so I used to be contacted by the State Department within the fall and mainly was an adviser to their applications there, together with a three-hour deep dive from the entire completely different committees or companies there …

I proceed to push this as a result of … if it got here from nature, there are particular issues we must always do otherwise to not have this occur once more. If it got here from a laboratory, there is a utterly completely different set of issues you want to do. It’s not a blame sport.”

There Are Several Ways to Make a Virus More Dangerous

Quay just lately revealed one other paper through which he reveals that the Wuhan Institute of Virology (WIV) can also be engaged on one other virus, the Nipah virus, which has a 90% lethality charge. It would not take a genius to determine what would possibly occur if a virus with that lethality obtained out. Quay explains:

“[The WIV] published an early paper on samples from COVID patients in the hospital … It’s the most-read paper from the beginning of the pandemic. I did a deep dive into their raw data. The sequence is 30,000 nucleotides — the raw data’s 55 million nucleotides. What you can see in there is a fingerprint of everything they’ve been doing for the last two years. They’re doing a lot of crazy research.”

As defined by Quay, the WIV has been round for about 40 years. In 2003, after SARS-Cov-1 emerged, the U.S. and France helped China refurbish the WIV right into a safer BSL 4 biolab, the one one in China. Since then, the WIV has change into a main laboratory for zoonotic viruses. It’s additionally one of many prime three laboratories for gain-of-function artificial biology, which will be completed in a number of methods.

If you understand what you wish to alter, you may insert a brand new artificial amino acid into the pathogen. If you do not have a exact thought of the change you wish to obtain, however you need the pathogen to adapt from an animal to a human, you are able to do what known as serial passage, the place the virus is handed by means of a collection of animal and human tissues. 

For instance, you can begin by infecting 20 humanized mice with a virus, then isolate the virus from the sickest mouse and provides it to a different 20. Humanized mice are genetically modified mice to have human lung tissue. After 4 or 5 passages like that, the virus may have mutated to assault and kill human hosts.

“The third approach is to drop massive chunks of fabric in there. For instance, the a part of the virus of SARS-CoV-2 that interacts with the cell is about 200 amino acids, so occasions three for nucleic acid, in order that’s 600. You can simply drop a giant piece of 600 in and immediately go from an animal to people, or no matter path you need.

So, these are the three [primary strategies]: Knowing what to do with single spots, randomly letting nature do it in serial passage, after which dropping massive chunks in.”

The Bayesian Theorem

As talked about, Bayesian evaluation is a statistical software utilizing chance distributions. The theorem was developed by Thomas Bayes, a seventeenth century Presbyterian minister and statistician-mathematician who revealed many papers throughout his lifetime. After his demise, his property found personal notes detailing a course of for understanding giant advanced occasions in a easy simple style. The Bayesian equation is A multiplied by B, divided by C. Quay explains:

“It’s precisely the identical factor we do when we’ve a favourite baseball group and we watch it through the season. Before the season, we all know what they did final yr. We know who the brand new gamers are, the brand new coaches, all these issues, and we provide you with what we name a previous prediction.

We rank the groups based on what we predict will occur on the World Series, and that is what’s referred to as our prior, our posterior chances. Then the season occurs and also you begin profitable video games, dropping video games, folks get injured, new gamers, transfers, and also you replace that each week.

At the beginning of the World Series, you are most likely fairly removed from the place you had been in the beginning of the season, since you’re now down to 2 groups however, nonetheless, you continue to do not know the ultimate evaluation. One of the caveats for this 140-page work is, on the finish, though I say there is a 1 in 500 probability it got here from nature, however meaning … 499 occasions out of 500 it got here from a laboratory.”

Bayesian Analysis of SARS-CoV-2 Origin

With regard to SARS-CoV-2, “A” could be the prior estimate of the probability of it coming from a lab or from nature. “B” is the brand new proof, the brand new chance that it got here from a lab, and “C” is the chance that it got here from nature. When you multiply A and B and divide it by C, you get a brand new A primary, a single chance. However, as new information accumulate, the reply adjustments.

“The very first thing I did was assume the prior probability it got here from nature or a lab, figuring out nothing, mainly. That must be your start line. Three papers knowledgeable that. One paper says that eight occasions a yr, there is a pure soar from nature to a human.

Another paper stated, annually, there is a lab leak in Asia, so 8-to-1 [in favor of natural origin]. That’s like 85% chance [that it came] from nature. I used three papers, and my start line was a 98% chance it got here from nature, figuring out nothing else.”

Quay didn’t embrace the three papers mainstream media and reality checkers have leaned on to debunk the lab origin theory, and in his paper he explains why they had been excluded. In brief, they relied on hypothesis and never science, so the clear bias and lack of scientific information made them too unreliable.

Next, he entered 26 completely different items of proof into the equation. The first piece of knowledge was the truth that the virus first emerged in Wuhan, China, which has by no means occurred earlier than. Wuhan has a inhabitants of 11 million folks. It’s a really city space with little man-nature contact. Wuhan additionally has one in every of solely three biosafety stage (BSL) 4 laboratories on the planet which can be conducting coronavirus analysis particularly. Next, he calculated chances.

“You know the realm of China; you understand the inhabitants of China. If the virus occurred randomly, what’s the probability it could occur in Wuhan? If there is a laboratory in Wuhan, what are the probabilities it could have escaped elsewhere in China and never appeared in Wuhan?

You do the flip. If it got here from nature, why did it find yourself in Wuhan? If it got here from Wuhan, what’s the chance it may have first appeared elsewhere in China? That hits your chances fairly exhausting out of the field. That was merchandise No. 1. Then you simply work by means of the others.”

Zoonotic Transmission

One key piece that makes a giant distinction on this Bayesian calculation is the query of zoonosis. In order for zoonosis to use, you need to have an animal with a spine (vertebrae) that’s contaminated with a microbe. Malaria, for instance, will not be a zoonotic illness, as a result of mosquitoes don’t have vertebrae. Malaria is a vector-transmitted illness.

The key to discovering the origin of a zoonotic transmission is to find the animal. If the animal is in the neighborhood, then zoonotic transmission happens by means of a pure course of. If the transmission happens in a lab, then it is a laboratory-acquired an infection, not a zoonotic transmission. Early on, we had been instructed as much as 70% of the earliest COVID sufferers had visited a number of markets in Wuhan, a few of which have dwell animals on the market.

The downside is SARS-CoV-2 was not present in any of the greater than 1,000 animal specimens collected from these markets. They additionally sampled greater than 1,000 items of frozen meals imported from exterior of China, all of which got here again clear. About 15% of environmental samples, nonetheless, did have the virus.

They additionally collected samples from all the opposite markets throughout the Hubei Province, the place Wuhan is situated. No virus. About 1,000 bats in Hubei had been examined, and no virus was discovered. Over 80,000 animals representing 209 species from each province of China had been ultimately examined, and no SARS-CoV-2 was discovered.

For comparability, SARS-1 was present in 85% of animals examined. The unique host was recognized because the civet cat. MERS, which got here from the Middle East, originated in a bat that had jumped to a camel earlier than turning right into a human virus, and it was present in 90% of animals. Yet, after the most important surveillance ever performed within the historical past of the world, having examined 80,000 animal specimens, not one has been discovered to hold SARS-CoV-2.

“In my Bayesian analysis … even though I should drop 80,000 into the denominator of my equation, what I did was I degraded it to the standard in clinical trials of biology to a P of .05. I said, ‘Despite the fact that zero out of 80,000 had this [virus], I’m going to treat this as if it’s a 1 in 20 event,’ because that’s the only way I could keep doing the analysis. Otherwise, I was done at the get-go,” Quay explains.

To be clear, this offers a really unfair benefit to the zoonotic origin concept, however Quay needed to have an entire evaluation of all of the parameters. Diversity is a trademark of nature, but there is not any variety in nature for this virus. Zoonotic proponents have argued that the virus should be present in excessive focus in an intermediate species, but not one out of 80,000 samples from 209 completely different animal species is a provider of the virus.

No Animal Reservoir or Intermediate Host Has Been Found

Another key piece of the evaluation is the virus itself. Bats are nature’s reservoirs for coronaviruses. The bats are by no means sickened by them, so the virus is rarely rooted out. It simply lives within the bats for many years, mutating and recombining with different viruses alongside the way in which. Bat-to-human contact could be very uncommon, so more often than not, the switch happens between the bats, the reservoir host and an intermediate host earlier than it enters the human inhabitants.

That’s what occurred with SARS-1 and MERS. Early circumstances of SARS-1 and MERS had been divided evenly between human to human transmission, and transmissions that occurred between completely different animals and people. This means each of those viruses had been probably zoonotic in origin.

As talked about earlier, Quay cites analysis displaying pure jumps from nature to a human happen eight occasions a yr, and lab escapes happen annually. That offers us an 8-to-1 probability of zoonotic origin. However, of the primary 259 circumstances in China, not one was traced again to animal contact. All had been human-to-human transmissions.

As famous by Quay, “This is the equivalent of going to Las Vegas and flipping a coin and getting heads 259 times. When you ask your statistician to do that, it’s a P value with 84 zeros and a number, so again, that’s absolutely impossible.”

To perceive how massive this quantity is, the estimated variety of atoms within the universe is 10 to the eightieth energy. Despite this displaying it is kind of inconceivable for SARS-CoV-2 to have a zoonotic origin, Quay gave this a P worth of simply 0.5 (or a 1 in 20 probability) — once more, simply to maintain the evaluation going.

“It’s not in the animals in nature. The virus is a pure virus … It hit the ground with one sequence, and it makes a mistake every two weeks randomly and if it’s the kind of mistake it really likes, it keeps it and then that one takes off,” he says.

“Again, SARS-1, MERS, each different zoonosis, when it jumps into people, it is a two-step course of. Initially, it jumps into people, nevertheless it would not have all of the issues it wants. It cannot make very many child viruses, et cetera, and so it burns out, after which it tries once more, and it tries once more. It jumps again to camels, that form of factor.

Eventually, it will get all of the mutations it must help human to human switch. Then you could have the muse for an epidemic, however that is an extended course of. With SARS-1 it took a yr and a half. With MERS, it took two and a half years in camels earlier than it obtained there. What does that imply although? Every time a human will get an an infection … there’s a document of their blood. They make antibodies to the virus.

Once you understand {that a} zoonosis goes to leap into people and depart a document within the hospital specimens and you’ve got a check from the epidemic of the virus itself, you may return into the hospital and discover specimens. Typically, it could actually vary from 1, to 4, to 7, to nearly 20% of the specimens.

For instance, folks working out there may have antibody proof that they’d the an infection, whether or not they knew it or not.

This is a really highly effective software … Because of the distinctive functionality of this virus to hit human to human transmission from the get-go, [Kristian Andersen, a virologist at the Scripps Research Institute in California who published a paper6 supporting zoonotic origin] predicted that there could be plenty of pre-epidemic seroconversion.

These are fancy phrases for ‘go right into a hospital, take samples out of the fridge, check them and discover a excessive proportion.’ Of course, folks took him up on that and examined over 9,900 banked specimens from December [2020] and earlier than in Wuhan. How many do you suppose they discovered that had been constructive?

My statistician says they need to have had 100 to 400. They obtained zero. You run the crank on that, and that is a 1 in one million chance.

The virus has the unbelievable functionality of being probably the most aggressive human to human virus that is ever been seen within the historical past of virology, nevertheless it doesn’t have the hallmark of how you’ll construct that in nature, which is pre-epidemic human contact. You cannot have each of those properties in the identical virus if it got here from nature.

Now, should you take a mouse that is been humanized in a laboratory to have human lungs and also you serial passage there, that’s an efficient solution to do it.

Amazingly, two months after the epidemic broke out, we’re February-March 2020 now, Dr. Shi on the Wuhan Institute of Virology and Dr. Baric in America, the No. 1 artificial biologist on the planet of coronavirus analysis in North Carolina, revealed a paper saying, ‘Hey, should you develop this virus in transgenic mice, it kills the mice and, by the way in which, they get mind infections, which is basically uncommon.’

I’m saying, ‘Yeah, that is most likely the experiment that was performed in 2019 that led to the spill.'” 

Again, utilizing extraordinarily conservative information, Quay’s evaluation reveals there is a 99.8% chance that SARS-CoV-2 is a laboratory creation. If you wish to learn by means of all of it, his paper will be downloaded from

Odd SARS-CoV-2 Proteins Suppress Your Immune Function

At the tip of the interview, Quay delivers one more bombshell. SARS-CoV-2 makes three main sorts of proteins. The first are the structural proteins for a virus — the spike, envelope and nucleoplasm proteins. It additionally makes proteins that take over the cells’ manufacturing course of, thereby permitting the virus to copy contained in the cell. In addition to these, it additionally makes two very odd proteins which can be excreted into your blood.

“These strange proteins, they’re not the virus, they’re not in the cell,” Quay explains. “When you get an infection, you get a fever, you get sweaty and you get chills, you feel like crap. That’s not the virus. That’s your own interferon signaling and it helps you fight the virus and probably in prehistory it told your fellow tribe members to isolate you in your own tent. So, it evolved as a social signal for survival of the tribe.”
