A science writer looks at the arguments for and against the SARS-CoV-2 virus being created in a lab or naturally occurring. The arguments against lab creation has a bunch of holes. But the kicker is that no one questioned this argument. Why? It’s a long detailed article but is well worth the read.
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.medium.com
The above sounds a lot like the arguments surrounding climate change doesn’t it?
If the SARS-CoV-2 virus was created in a lab the American taxpayer in all likelihood would have funded it. How’s that for a kick in the pants?
Because, by a strange twist in the story, her work was funded by the National Institute of Allergy and Infectious Diseases (NIAID), a part of the U.S. National Institutes of Health (NIH). And grant proposals that funded her work, which are a matter of public record, specify exactly what she planned to do with the money.
The grants were assigned to the prime contractor, Dr. Daszak of the EcoHealth Alliance, who subcontracted them to Dr. Shi. Here are extracts from the grants for fiscal years 2018 and 2019. “CoV” stands for coronavirus and “S protein” refers to the virus’s spike protein.
“Test predictions of CoV inter-species transmission. Predictive models of host range (i.e. emergence potential) will be tested experimentally using reverse genetics, pseudovirus and receptor binding assays, and virus infection experiments across a range of cell cultures from different species and humanized mice.”
“We will use S protein sequence data, infectious clone technology, in vitro and in vivo infection experiments and analysis of receptor binding to test the hypothesis that % divergence thresholds in S protein sequences predict spillover potential.”
What this means, in non-technical language, is that Dr. Shi set out to create novel coronaviruses with the highest possible infectivity for human cells. Her plan was to take genes that coded for spike proteins possessing a variety of measured affinities for human cells, ranging from high to low. She would insert these spike genes one by one into the backbone of a number of viral genomes (“reverse genetics” and “infectious clone technology”), creating a series of chimeric viruses. These chimeric viruses would then be tested for their ability to attack human cell cultures (“in vitro”) and humanized mice (“in vivo”). And this information would help predict the likelihood of “spillover,” the jump of a coronavirus from bats to people.medium.com
Who is the “she” in the story? She is China’s leading expert on bat viruses, Dr. Shi Zheng-li. We can’t investigate if the virus came from her lab because her records are sealed.
There are tons of gems in this long article. Here’s a goody. The now infamous lab in Wuhan studied these viruses in a lab where the safety precautions were no better than a standard dentist’s office.
Before 2020, the rules followed by virologists in China and elsewhere required that experiments with the SARS1 and MERS viruses be conducted in BSL3 conditions. But all other bat coronaviruses could be studied in BSL2, the next level down. BSL2 requires taking fairly minimal safety precautions, such as wearing lab coats and gloves, not sucking up liquids in a pipette, and putting up biohazard warning signs. Yet a gain-of-function experiment conducted in BSL2 might produce an agent more infectious than either SARS1 or MERS. And if it did, then lab workers would stand a high chance of infection, especially if unvaccinated.
Much of Dr. Shi’s work on gain-of-function in coronaviruses was performed at the BSL2 safety level, as is stated in her publications and other documents. She has said in an interview with Science magazine that “The coronavirus research in our laboratory is conducted in BSL-2 or BSL-3 laboratories.”
“It is clear that some or all of this work was being performed using a biosafety standard — biosafety level 2, the biosafety level of a standard US dentist’s office — that would pose an unacceptably high risk of infection of laboratory staff upon contact with a virus having the transmission properties of SARS-CoV-2,” says Dr. Ebright.medium.com
No animal host has been identified as the source for SARS-CoV-2. That’s not what we’ve been told.
The uniform structure of SARS2 genomes gives no hint of any passage through an intermediate animal host, and no such host has been identified in nature.medium.com
There is a feature of the virus that has only been found in laboratory created viruses. Go figure!
So it’s hard to explain how the SARS2 virus picked up its furin cleavage site naturally, whether by mutation or recombination.
That leaves a gain-of-function experiment. For those who think SARS2 may have escaped from a lab, explaining the furin cleavage site is no problem at all. “Since 1992 the virology community has known that the one sure way to make a virus deadlier is to give it a furin cleavage site at the S1/S2 junction in the laboratory,” writes Dr. Steven Quay, a biotech entrepreneur interested in the origins of SARS2. “At least eleven gain-of-function experiments, adding a furin site to make a virus more infective, are published in the open literature, including [by] Dr. Zhengli Shi, head of coronavirus research at the Wuhan Institute of Virology.”medium.com
It can’t be proven one way or another if the virus came from a lab or developed in nature. The reason it can’t be proven is that the records at the lab are sealed.
It’s documented that researchers at the Wuhan Institute of Virology were doing gain-of-function experiments designed to make coronaviruses infect human cells and humanized mice. This is exactly the kind of experiment from which a SARS2-like virus could have emerged. The researchers were not vaccinated against the viruses under study, and they were working in the minimal safety conditions of a BSL2 laboratory. So escape of a virus would not be at all surprising. In all of China, the pandemic broke out on the doorstep of the Wuhan institute. The virus was already well adapted to humans, as expected for a virus grown in humanized mice. It possessed an unusual enhancement, a furin cleavage site, which is not possessed by any other known SARS-related beta-coronavirus, and this site included a double arginine codon also unknown among beta-coronaviruses. What more evidence could you want, aside from the presently unobtainable lab records documenting SARS2’s creation?medium.com
Because the lab is in China we will never find out the truth. Here’s another gem near the end of the article. Is our beloved Dr. Fauci partly responsible for the creation of SARS-CoV-2?
The responsibility of the NIAID and NIH is even more acute because for the first three years of the grant to EcoHealth Alliance there was a moratorium on funding gain-of-function research. Why didn’t the two agencies therefore halt the Federal funding as apparently required to do so by law? Because someone wrote a loophole into the moratorium.
The moratorium specifically barred funding any gain-of-function research that increased the pathogenicity of the flu, MERS or SARS viruses. But then a footnote on p.2 of the moratorium document states that “An exception from the research pause may be obtained if the head of the USG funding agency determines that the research is urgently necessary to protect the public health or national security.”
This seems to mean that either the director of the NIAID, Dr. Anthony Fauci, or the director of the NIH, Dr. Francis Collins, or maybe both, would have invoked the footnote in order to keep the money flowing to Dr. Shi’s gain-of-function research.medium.com
