Evidence on the origin of Covid leads to lab in Wuhan – Former NY Times Science Editor
In the millions of articles, opinion pieces, and news stories written about Covid there is one topic that is more important than all the others. It’s more important than masks, vaccines, or lockdown measures. The origin of the virus is critical because no matter how many people die from covid, or how many businesses are wiped out, it’s critical that IF the next virus can be stopped, it mu st be.
A science writer named Nicholas Wade has written the most thorough study on the origins of Covid to be released to the public. Wade has worked with Nature, Science, and the New York Times, but this article was released on the public platform Medium. In this article Wade goes through three possible scenarios and then draws the most likely conclusion. This is a long read, but it might be the most important article yet written during this pandemic.

Origin of Covid — Following the Clues
Did people or nature open Pandora’s box at Wuhan?

The Covid-19 pandemic has disrupted lives the world over for more than a year. Its death toll will soon reach three million people. Yet the origin of pandemic remains uncertain: the political agendas of governments and scientists have generated thick clouds of obfuscation, which the mainstream press seems helpless to dispel.
In what follows I will sort through the available scientific facts, which hold many clues as to what happened, and provide readers with the evidence to make their own judgments. I will then try to assess the complex issue of blame, which starts with, but extends far beyond, the government of China.
By the end of this article, you may have learned a lot about the molecular biology of viruses. I will try to keep this process as painless as possible. But the science cannot be avoided because for now, and probably for a long time hence, it offers the only sure thread through the maze.
The virus that caused the pandemic is known officially as SARS-CoV-2, but can be called SARS2 for short. As many people know, there are two main theories about its origin. One is that it jumped naturally from wildlife to people. The other is that the virus was under study in a lab, from which it escaped. It matters a great deal which is the case if we hope to prevent a second such occurrence.
I’ll describe the two theories, explain why each is plausible, and then ask which provides the better explanation of the available facts. It’s important to note that so far there is no direct evidence for either theory. Each depends on a set of reasonable conjectures but so far lacks proof. So I have only clues, not conclusions, to offer. But those clues point in a specific direction. And having inferred that direction, I’m going to delineate some of the strands in this tangled skein of disaster.
A Tale of Two Theories
After the pandemic first broke out in December 2019, Chinese authorities reported that many cases had occurred in the wet market — a place selling wild animals for meat — in Wuhan. This reminded experts of the SARS1 epidemic of 2002 in which a bat virus had spread first to civets, an animal sold in wet markets, and from civets to people. A similar bat virus caused a second epidemic, known as MERS, in 2012. This time the intermediary host animal was camels.
The decoding of the virus’s genome showed it belonged to a viral family known as beta-coronaviruses, to which the SARS1 and MERS viruses also belong. The relationship supported the idea that, like them, it was a natural virus that had managed to jump from bats, via another animal host, to people. The wet market connection, the only other point of similarity with the SARS1 and MERS epidemics, was soon broken: Chinese researchers found earlier cases in Wuhan with no link to the wet market. But that seemed not to matter when so much further evidence in support of natural emergence was expected shortly.
Wuhan, however, is home of the Wuhan Institute of Virology, a leading world center for research on coronaviruses. So the possibility that the SARS2 virus had escaped from the lab could not be ruled out. Two reasonable scenarios of origin were on the table.
From early on, public and media perceptions were shaped in favor of the natural emergence scenario by strong statements from two scientific groups. These statements were not at first examined as critically as they should have been.
“We stand together to strongly condemn conspiracy theories suggesting that COVID-19 does not have a natural origin,” a group of virologists and others wrote in the Lancet on February 19, 2020, when it was really far too soon for anyone to be sure what had happened. Scientists “overwhelmingly conclude that this coronavirus originated in wildlife,” they said, with a stirring rallying call for readers to stand with Chinese colleagues on the frontline of fighting the disease.
Contrary to the letter writers’ assertion, the idea that the virus might have escaped from a lab invoked accident, not conspiracy. It surely needed to be explored, not rejected out of hand. A defining mark of good scientists is that they go to great pains to distinguish between what they know and what they don’t know. By this criterion, the signatories of the Lancet letter were behaving as poor scientists: they were assuring the public of facts they could not know for sure were true.
It later turned out that the Lancet letter had been organized and drafted by Peter Daszak, president of the EcoHealth Alliance of New York. Dr. Daszak’s organization funded coronavirus research at the Wuhan Institute of Virology. If the SARS2 virus had indeed escaped from research he funded, Dr. Daszak would be potentially culpable. This acute conflict of interest was not declared to the Lancet’s readers. To the contrary, the letter concluded, “We declare no competing interests.”
Virologists like Dr. Daszak had much at stake in the assigning of blame for the pandemic. For 20 years, mostly beneath the public’s attention, they had been playing a dangerous game. In their laboratories they routinely created viruses more dangerous than those that exist in nature. They argued they could do so safely, and that by getting ahead of nature they could predict and prevent natural “spillovers,” the cross-over of viruses from an animal host to people. If SARS2 had indeed escaped from such a laboratory experiment, a savage blowback could be expected, and the storm of public indignation would affect virologists everywhere, not just in China. “It would shatter the scientific edifice top to bottom,” an MIT Technology Review editor, Antonio Regalado, said in March 2020.
A second statement which had enormous influence in shaping public attitudes was a letter (in other words an opinion piece, not a scientific article) published on 17 March 2020 in the journal Nature Medicine. Its authors were a group of virologists led by Kristian G. Andersen of the Scripps Research Institute. “Our analyses clearly show that SARS-CoV-2 is not a laboratory construct or a purposefully manipulated virus,” the five virologists declared in the second paragraph of their letter.
Unfortunately this was another case of poor science, in the sense defined above. True, some older methods of cutting and pasting viral genomes retain tell-tale signs of manipulation. But newer methods, called “no-see-um” or “seamless” approaches, leave no defining marks. Nor do other methods for manipulating viruses such as serial passage, the repeated transfer of viruses from one culture of cells to another. If a virus has been manipulated, whether with a seamless method or by serial passage, there is no way of knowing that this is the case. Dr. Andersen and his colleagues were assuring their readers of something they could not know.
The discussion part their letter begins, “It is improbable that SARS-CoV-2 emerged through laboratory manipulation of a related SARS-CoV-like coronavirus”. But wait, didn’t the lead say the virus had clearly not been manipulated? The authors’ degree of certainty seemed to slip several notches when it came to laying out their reasoning.
The reason for the slippage is clear once the technical language has been penetrated. The two reasons the authors give for supposing manipulation to be improbable are decidedly inconclusive.
First, they say that the spike protein of SARS2 binds very well to its target, the human ACE2 receptor, but does so in a different way from that which physical calculations suggest would be the best fit. Therefore the virus must have arisen by natural selection, not manipulation.
If this argument seems hard to grasp, it’s because it’s so strained. The authors’ basic assumption, not spelt out, is that anyone trying to make a bat virus bind to human cells could do so in only one way. First they would calculate the strongest possible fit between the human ACE2 receptor and the spike protein with which the virus latches onto it. They would then design the spike protein accordingly (by selecting the right string of amino acid units that compose it). But since the SARS2 spike protein is not of this calculated best design, the Andersen paper says, therefore it can’t have been manipulated.
But this ignores the way that virologists do in fact get spike proteins to bind to chosen targets, which is not by calculation but by splicing in spike protein genes from other viruses or by serial passage. With serial passage, each time the virus’s progeny are transferred to new cell cultures or animals, the more successful are selected until one emerges that makes a really tight bind to human cells. Natural selection has done all the heavy lifting. The Andersen paper’s speculation about designing a viral spike protein through calculation has no bearing on whether or not the virus was manipulated by one of the other two methods.
The authors’ second argument against manipulation is even more contrived. Although most living things use DNA as their hereditary material, a number of viruses use RNA, DNA’s close chemical cousin. But RNA is difficult to manipulate, so researchers working on coronaviruses, which are RNA-based, will first convert the RNA genome to DNA. They manipulate the DNA version, whether by adding or altering genes, and then arrange for the manipulated DNA genome to be converted back into infectious RNA.
Only a certain number of these DNA backbones have been described in the scientific literature. Anyone manipulating the SARS2 virus “would probably” have used one of these known backbones, the Andersen group writes, and since SARS2 is not derived from any of them, therefore it was not manipulated. But the argument is conspicuously inconclusive. DNA backbones are quite easy to make, so it’s obviously possible that SARS2 was manipulated using an unpublished DNA backbone.
And that’s it. These are the two arguments made by the Andersen group in support of their declaration that the SARS2 virus was clearly not manipulated. And this conclusion, grounded in nothing but two inconclusive speculations, convinced the world’s press that SARS2 could not have escaped from a lab. A technical critique of the Andersen letter takes it down in harsher words.
Science is supposedly a self-correcting community of experts who constantly check each other’s work. So why didn’t other virologists point out that the Andersen group’s argument was full of absurdly large holes? Perhaps because in today’s universities speech can be very costly. Careers can be destroyed for stepping out of line. Any virologist who challenges the community’s declared view risks having his next grant application turned down by the panel of fellow virologists that advises the government grant distribution agency.
The Daszak and Andersen letters were really political, not scientific statements, yet were amazingly effective. Articles in the mainstream press repeatedly stated that a consensus of experts had ruled lab escape out of the question or extremely unlikely. Their authors relied for the most part on the Daszak and Andersen letters, failing to understand the yawning gaps in their arguments. Mainstream newspapers all have science journalists on their staff, as do the major networks, and these specialist reporters are supposed to be able to question scientists and check their assertions. But the Daszak and Andersen assertions went largely unchallenged.
Doubts about natural emergence
Natural emergence was the media’s preferred theory until around February 2021 and the visit by a World Health Organization commission to China. The commission’s composition and access were heavily controlled by the Chinese authorities. Its members, who included the ubiquitous Dr. Daszak, kept asserting before, during and after their visit that lab escape was extremely unlikely. But this was not quite the propaganda victory the Chinese authorities may have been hoping for. What became clear was that the Chinese had no evidence to offer the commission in support of the natural emergence theory.
This was surprising because both the SARS1 and MERS viruses had left copious traces in the environment. The intermediary host species of SARS1 was identified within four months of the epidemic’s outbreak, and the host of MERS within nine months. Yet some 15 months after the SARS2 pandemic began, and a presumably intensive search, Chinese researchers had failed to find either the original bat population, or the intermediate species to which SARS2 might have jumped, or any serological evidence that any Chinese population, including that of Wuhan, had ever been exposed to the virus prior to December 2019. Natural emergence remained a conjecture which, however plausible to begin with, had gained not a shred of supporting evidence in over a year.
And as long as that remains the case, it’s logical to pay serious attention to the alternative conjecture, that SARS2 escaped from a lab.
Why would anyone want to create a novel virus capable of causing a pandemic?

By the way.. Medium is a fascinating place. If you haven’t checked it out yet here’s a link to medium.com.
From About Medium:
We’re an open platform where 170 million readers come to find insightful and dynamic thinking. Here, expert and undiscovered voices alike dive into the heart of any topic and bring new ideas to the surface. Our purpose is to spread these ideas and deepen understanding of the world.
From the Brownstone Institute
Anthony “I represent science” Fauci can now stand beside Richard “I am not a crook” Nixon in the history books as someone who received the poison pill of a preemptive pardon.
While Nixon was pardoned for specific charges related to Watergate, the exact crimes for which Fauci was pardoned are not specified. Rather, the pardon specifies:
Baseless and politically motivated investigations wreak havoc on the lives, safety, and financial security of targeted individuals and their families. Even when individuals have done nothing wrong – and in fact have done the right things – and will ultimately be exonerated, the mere fact of being investigated and prosecuted can irreparably damage reputations and finances.
In other words, the dying breath of the Biden administration appears to be pardoning Fauci for crimes he didn’t commit, which would seem to make a pardon null and void. The pardon goes further than simply granting clemency for crimes. Clemency usually alleviates the punishment associated with a crime, but here Biden attempts to alleviate the burden of investigations and prosecutions, the likes of which our justice system uses to uncover crimes.
It’s one thing to pardon someone who has been subjected to a fair trial and convicted, to say they have already paid their dues. Gerald Ford, in his pardon of Richard Nixon, admitted that Nixon had already paid the high cost of resigning from the highest office in the land. Nixon’s resignation came as the final chapter of prolonged investigations into his illegal and unpresidential conduct during Watergate, and those investigations provided us the truth we needed to know that Nixon was a crook and move on content that his ignominious reputation was carve d into stone for all of history.
Fauci, meanwhile, has evaded investigations on matters far more serious than Watergate. In 2017, DARPA organized a grant call – the PREEMPT call – aiming to preempt pathogen spillover from wildlife to people. In 2018 a newly formed collaborative group of scientists from the US, Singapore, and Wuhan wrote a grant – the DEFUSE grant – proposing to modify a bat sarbecovirus in Wuhan in a very unusual way. DARPA did not fund the team because their work was too risky for the Department of Defense, but in 2019 Fauci’s NIAID funded this exact set of scientists who never wrote a paper together prior or since. In late 2019, SARS-CoV-2 emerged in Wuhan with the precise modifications proposed in the DEFUSE grant submitted to PREEMPT.
It’s reasonable to be concerned that this line of research funded by Fauci’s NIAID may have caused the pandemic. In fact, if we’re sharp-penciled and honest with our probabilities, it’s likely beyond reasonable doubt that SARS-CoV-2 emerged as a consequence of research proposed in DEFUSE. What we don’t know, however, is whether the research proceeded with US involvement or not.
Congress used its constitutionally-granted investigation and oversight responsibilities to investigate and oversee NIAID in search of answers. In the process of these investigations, they found endless pages of emails with unjustified redactions, evidence that Fauci’s FOIA lady could “make emails disappear,” Fauci’s right-hand-man David Morens aided the DEFUSE authors as they navigated disciplinary measures at NIH and NIAID, and there were significant concerns that NIAID sought to obstruct investigations and destroy federal records.
Such obstructive actions did not inspire confidence in the innocence of Anthony Fauci or the US scientists he funded in 2019. On the contrary, Fauci testified twice under oath saying NIAID did not fund gain-of-function research of concern in Wuhan…but then we discovered a 2018 progress report of research NIAID funded in Wuhan revealing research they funded had enhanced the transmissibility of a bat SARS-related coronavirus 10,000 times higher than the wild virus. That is, indisputably, gain-of-function research of concern. Fauci thus lied to the American public and perjured himself in his testimony to Congress, and Senator Rand Paul (R-KY) has referred Fauci’s perjury charges to the Department of Justice.
What was NIAID trying to preempt with their obstruction of Congressional investigations? What is Biden trying to preempt with his pardon of Fauci? Why do we not have the 2019 NIAID progress report from the PI’s who submitted DEFUSE to PREEMPT and later received funding from NIAID?
It is deplorable for Biden to preemptively pardon Fauci on his last day in office, with so little known about the research NIAID funded in 2019 and voters so clearly eager to learn more. With Nixon’s preemptive pardon, the truth of his wrongdoing was known and all that was left was punishment. With Fauci’s preemptive pardon, the truth is not yet known, NIAID officials in Fauci’s orbit violated federal records laws in their effort to avoid the truth from being known, and Biden didn’t preemptively pardon Fauci to grant clemency and alleviate punishment, but to stop investigations and prosecutions the likes of which could uncover the truth.
I’m not a Constitutional scholar prepared to argue the legality of this maneuver, but I am an ethical human being, a scientist who contributed another grant to the PREEMPT call, and a scientist who helped uncover some of the evidence consistent with a lab origin and quantify the likelihood of a lab origin from research proposed in the DEFUSE grant. Any ethical human being knows that we need to know what caused the pandemic, and to deprive the citizenry of such information from open investigations of NIAID research in 2019 would be to deprive us of critical information we need to self-govern and elect people who manage scientific risks in ways we see fit. As a scientist, there are critical questions about bioattribution that require testing, and the way to test our hypotheses is to uncover the redacted and withheld documents from Fauci’s NIAID in 2019.
The Biden administration’s dying breath was to pardon Anthony Fauci not for the convictions for crimes he didn’t commit (?) but to avoid investigations that could be a reputational and financial burden for Anthony Fauci. A pardon to preempt an investigation is not a pardon; it is obstruction. The Biden administration’s dying breath is to obstruct our pursuit of truth and reconciliation on the ultimate cause of 1 million Americans’ dying breaths.
To remind everyone what we still need to know, it helps to look through the peephole of what we’ve already found to inspire curiosity about what else we’d find if only the peephole could be widened. Below is one of the precious few emails investigative journalists pursuing FOIAs against NIAID have managed to obtain from the critical period when SARS-CoV-2 is believed to have emerged. The email connects DEFUSE PI’s Peter Daszak (EcoHealth Alliance), Ralph Baric (UNC), Linfa Wang (Duke-NUS), Ben Hu (Wuhan Institute of Virology), Shi ZhengLi (Wuhan Institute of Virology) and others in October 2019. The subject line “NIAID SARS-CoV Call – October 30/31” connects these authors to NIAID.
It is approximately in that time range – October/November 2019 – when SARS-CoV-2 is hypothesized to have entered the human population in Wuhan. When it emerged, SARS-CoV-2 was unique among sarbecoviruses in having a furin cleavage site, as proposed by these authors in their 2019 DEFUSE grant. Of all the places the furin cleavage site could be, the furin cleavage site of SARS-CoV-2 was in the S1/S2 junction of the Spike protein, precisely as proposed by these authors.
In order to insert a furin cleavage site in a SARS-CoV, however, the researchers would’ve needed to build a reverse genetic system, i.e. a DNA copy of the virus. SARS-CoV-2 is unique among coronaviruses in having exactly the fingerprint we would expect from reverse genetic systems. There is an unusual even spacing in the cutting/pasting sites for the enzymes BsaI and BsmBI and an anomalous hot-spot of silent mutations in precisely these sites, exactly as researchers at the Wuhan Institute of Virology have done for other coronavirus reverse genetic systems. The odds of such an extreme synthetic-looking pattern occurring in nature are, conservatively, about 1 in 50 billion.
The virus did not emerge in Bangkok, Hanoi, Bago, Kunming, Guangdong, or any of the myriad other places with similar animal trade networks and greater contact rates between people and sarbecovirus reservoirs. No. The virus emerged in Wuhan, the exact place and time one would expect from DEFUSE.
With all the evidence pointing the hounds towards NIAID, it is essential for global health security that we further investigate the research NIAID funded in 2019. It is imperative for our constitutional democracy, for our ability to self-govern, that we learn the truth. The only way to learn the truth is to investigate NIAID, the agency Fauci led for 38 years, the agency that funded gain-of-function research of concern, the agency named in the October 2019 call by DEFUSE PI’s, the agency that funded this exact group in 2019.
A preemptive pardon prior to the discovery of truth is a fancy name for obstruction of justice. The Biden administration’s dying breath must be challenged, and we must allow Congress and the incoming administration to investigate the possibility that Anthony Fauci’s NIAID-supported research caused the Covid-19 pandemic.

BREAKING: Days before Trump Inauguration HHS fires doctor in charge of gain of function research project
Dr. Daszak will likely be protected by the DoD & CIA from additional penalties.
By John Leake
HHS Formally Debars EcoHealth Alliance, President Peter Daszak Fired.
On January 17, 2025—just three days before President Trump is to be sworn in—Congress issued a press release with the following statement:
Today, after an eight-month investigation, the U.S. Department of Health and Human Services (HHS) cut off all funding and formally debarred EcoHealth Alliance Inc. (EcoHealth) and its former President, Dr. Peter Daszak, for five years based on evidence uncovered by the Select Subcommittee on the Coronavirus Pandemic.
As far as I can tell, the New York Times did not report this story, though the New York Post did.
More interesting than the superficial news reporting is the HHS ACTION REFERRAL MEMORANDUM recommending that Dr. Peter Daszak be barred from participating in United States Federal Government procurement and nonprocurement programs.
The Memorandum also states:
Dr. Peter Daszak was the President and Chief Executive Officer of EHA from 2009 until his termination, effective January 6, 2025. Dr. Daszak was the Project Director (PD)/Principal Investigator (PI) for Grant Number 1R01AI110964-01.
I am not sure what to make of this document, which is written in such an arcane and convoluted style that it challenges the attention span of even the most focused reader.
I have been researching this story for four years, and I found the following paragraphs the most intriguing:
9. In a letter dated May 28, 2016, the NIAID contacted EHA concerning possible GoF research based on information submitted in its most recent Year 2 RPPR. The NIAID notified EHA that GoF research conducted under Grant Number 5R01AI110964-03 would be subject to the October 17, 2014, United States Federal Government funding pause, and that per the funding pause announcement, new United States Federal Government funding would not be released for GoF research projects that may be reasonably anticipated to confer attributes to influenza, MERS, or SARS viruses such that the virus would have enhanced pathogenicity and/or transmissibility in mammals via the respiratory route. In the letter, the NIAID requested that EHA provide a determination within 15 days of the date of the letter as to whether EHA’s research under Grant Number 5R01AI110964-03 did or did not include GoF work subject to the funding pause.
10. In a letter dated June 8, 2016, EHA provided a response to the NIAID’s May 28, 2016 letter. EHA explained that the goal of its proposed work was to construct MERS and MERS-like chimeric CoVs in order to understand the potential origins of MERSCoV in bats by studying bat MERS-like CoVs in detail. EHA stated that it believed it was highly unlikely that the proposed work would have any pathogenic potential, but that should any of these recombinants show evidence of enhanced virus growth greater than certain specified benchmarks involving log growth increases, or grow more efficiently in human airway epithelial cells, EHA would immediately: (1) stop all experiments with the mutant, (2) inform the NIAID Program Officer of these results, and (3) participate in decision-making trees to decide appropriate paths forward.
11. Based on the information provided by EHA, the NIAID concluded that the proposed work was not subject to the GoF research pause. In a letter dated July 7, 2016, however, the NIAID informed EHA that should any of the MERS-like or SARS-like chimeras generated under the grant show evidence of enhanced virus growth greater than 1 log over the parental backbone strain, EHA must stop all experiments with these viruses and provide the NIAID Program Officer and Grants Management Specialist, and WIV Institutional Biosafety Committee, with the relevant data and information related to these unanticipated outcomes.
Note that various statements in the above paragraphs are inconsistent with what Baric et al. state in their 2015 paper A SARS-like cluster of circulating bat coronavirus shows potential for human emergence—a research paper funded by the NIAID EcoHealth Grant “Understanding the Risk of Bat Coronavirus Emergence.”
As the authors state in the section on Biosafety and biosecurity:
Reported studies were initiated after the University of North Carolina Institutional Biosafety Committee approved the experimental protocol (Project Title: Generating infectious clones of bat SARS-like CoVs; Lab Safety Plan ID: 20145741; Schedule G ID: 12279). These studies were initiated before the US Government Deliberative Process Research Funding Pause on Selected Gain-of-Function Research Involving Influenza, MERS and SARS Viruses (http://www.phe.gov/s3/
dualuse/Documents/gain-of- function.pdf). This paper has been reviewed by the funding agency, the NIH. Continuation of these studies was requested, and this has been approved by the NIH.
As I noted in my series of essays titled The Great SARS-CoV-2 Charade, one of the silliest lies told by Dr. Anthony Fauci has been his insistence that NIAID did not approve Gain-of-Function work by EcoHealth.
Fauci has repeatedly asserted this in a loud and vexed tone, as though he is outraged by the mere proposition. And yet, Ralph Baric and his colleagues—including Zhengli-Li Shi at the Wuhan Institute of Virology—plainly state in their 2015 paper that their Gain-of-Function experiments, performed in Baric’s UNC lab and Zhengli-Li Shi’s lab in Wuhan, were grandfathered in, given that they were funded before the 2014 Pause.
Another statement (in paragraph 11 of the recent HHS Action Referral Memo) that deserves special scrutiny is the following:
In a letter dated July 7, 2016, however, the NIAID informed EHA that should any of the MERS-like or SARS-like chimeras generated under the grant show evidence of enhanced virus growth greater than 1 log over the parental backbone strain, EHA must stop all experiments with these viruses and provide the NIAID Program Officer and Grants Management Specialist, and WIV Institutional Biosafety Committee, with the relevant data and information related to these unanticipated outcomes.
Again, it’s tough to interpret this statement, given that Baric et al. had, by the own admission, already generated chimeras that “replicate efficiently in primary human airway cells and achieve in vitro titers equivalent to epidemic strains of SARS-CoV.”
Let’s review what Baric et al. state in their Abstract about the functionality of the chimeric virus (named SHCOI4-MA15) they claimed to have generated. Using humanized mice (genetically modified to have primary human airway cells) as their experimental animals, the authors state:
Using the SARS-CoV reverse genetics system2, we generated and characterized a chimeric virus expressing the spike of bat coronavirus SHC014 in a mouse-adapted SARS-CoV backbone.
The results indicate that group 2b viruses encoding the SHC014 spike in a wild-type backbone can efficiently use multiple orthologs of the SARS receptor human angiotensin converting enzyme II (ACE2), replicate efficiently in primary human airway cells and achieve in vitro titers equivalent to epidemic strains of SARS-CoV. Additionally, in vivo experiments demonstrate replication of the chimeric virus in mouse lung with notable pathogenesis.
To this day, no legal authority that I am aware of has investigated the question: What became of the the chimeras SHC014-MA15 and WIV1-MA15? The latter chimera was documented by Baric et al. in their March 2016 paper titled SARS-like WIV1-CoV poised for human emergence—a chimera “that replaced the SARS spike with the WIV1 spike within the mouse-adapted backbone.”
What did the Wuhan Institute of Virology do with these chimeras? Did its researchers continue to modify and experiment with these chimeras?
Another exceedingly silly claim made by U.S. government officials—including members of Congress—is that the true origin of SARS-CoV-2 is likely to remain a mystery, given that the Chinese government and military will almost certainly never agree to perform a full and transparent investigation of their Wuhan Institute of Virology.
What did the U.S. government expect when it agreed to share cutting edge American biotechnology with the Wuhan Institute of Virology, which has long been known to be run by the Chinese military?
One grows weary of our U.S. government officials evading responsibility by pretending to be imbeciles or by revealing themselves to be true imbeciles.
