Why Did Dr. Shi and the Wuhan Institute of Virology Hide the Precursor to SARS-CoV-2?
Last Updated on October 14, 2022 by Shaun Snapp
- The Independent Science News developed interesting questions for the Wuhan Institute of Virology regarding the hiding of the precursors to SARS-CoV-2.
Dr. Shi and the Wuhan Insitute of Virology engaged in some very strange behavior obscuring the origin of the virus which most likely was the precursor or basis for SARS-CoV-2.
This issue with the precursor RaTG13 virus is explained in the following quotation.
BtCoV/4991 and RaTG13
In all the discussions of the origin of the COVID-19 pandemic, enormous scientific attention has been paid to the molecular character of the SARS-CoV-2 virus, including its novel genome sequence in comparison with its near relatives.
In stark contrast, virtually no attention has been paid to the physical provenance of those nearest genetic relatives, its presumptive ancestors, which are two viral sequences named BtCoV/4991 and RaTG13. BtCoV/4991 and RaTG13 were collected from a mineshaft in Yunnan province, China, in 2012/2013 by researchers from the lab of Zheng-li Shi at the Wuhan Institute of Virology.
The specifics of this mystery disease have been virtually forgotten; however, they are described in a Chinese Master’s thesis written in 2013 by a doctor who supervised their treatment. We arranged to have this Master’s thesis translated into English. The evidence it contains has led us to reconsider everything we thought we knew about the origins of the COVID-19 pandemic. It has also led us to theorise a plausible route by which an apparently isolated disease outbreak in a mine in 2012 led to a global pandemic in 2019.
The theory can account for the origin of the polybasic furin cleavage site, which is a region of the viral spike protein that makes it susceptible to cleavage by the host enzyme furin and which greatly enhances viral spread in the body. This furin site is novel to SARS-CoV-2 compared to its near relatives (Coutard, et al., 2020).
The theory further explains why the virus has barely evolved since the pandemic began, which is also a deeply puzzling aspect of a virus supposedly new to humans (Zhan et al., 2020; van Dorp et al., 2020; Chaw et al., 2020). Lastly, the theory neatly explains why SARS-CoV-2 targets the lungs, which is unusual for a coronavirus (Huang et al., 2020).
An intriguing alternative possibility is that SARS-CoV-2 acquired its furin site directly from the miner’s lungs. Humans possess an epithelial sodium channel protein called ENaC-a whose furin cleavage site is identical over eight amino acids to SARS-CoV-2 (Anand et al., 2020). ENaC-a protein is present in the same airway epithelial and lung tissues infected by SARS-CoV-2. It is known from plants that positive-stranded RNA viruses recombine readily with host mRNAs (Greene and Allison, 1994; Greene and Allison, 1996; Lommel and Xiong, 1991; Borja et al., 2007). The same evidence base is not available for positive-stranded animal RNA viruses, (though see Gorbalenya, 1992) but if plant viruses are a guide then acquisition of its furin site via recombination with the mRNA which encodes ENaC-a by SARS-CoV-2 is a strong possibility.
A further feature of SARS-CoV-2 has been the very limited adaptive evolution of its genome since the pandemic began (Zhan et al., 2020; van Dorp et al., 2020; Starr et al., 2020). It is a well-established principle that viruses that jump species undergo accelerated evolutionary change in their new host (e.g. Baric et al., 1997). Thus, SARS and MERS (both coronaviruses) underwent rapid and readily detectable adaptation to their new human hosts (Forni et al., 2017; Dudas and Rambaut, 2016). Such an adaptation period has not been observed for SARS-CoV-2 even though it has now infected many more individuals than SARS or MERS did. This has even led to suggestions that the SARS-CoV-2 virus had a period of cryptic circulation in humans infections that predated the pandemic (Chaw et al., 2020). – Independent Science News
This research by Independent Science News is not the focus of this article, rather the evidence of Dr. Shi lying is.
Focusing on The Two Coronavirus Precursors
In our own search to resolve the COVID-19 origin question we chose to focus on the provenance of the coronavirus genome sequences BtCoV/4991 and RaTG13, since these are the most closely related sequences to SARS-CoV-2 (98.7% and 96.2% identical respectively).
In a March 2020 interview with Scientific American Zeng-li Shi dismissed the significance of these deaths, claiming the miners died of fungal infections. Indeed, no miners or deaths are mentioned in the paper published by the Shi lab documenting the collection of RaTG13 (Ge et al., 2016). But Shi’s assessment does not tally with any other contemporaneous accounts of the miners and their illness (Rahalkar and Bahulikar, 2020). As these authors have pointed out, Science magazine wrote up part of the incident in 2014 as A New Killer Virus in China? – Independent Science News
Why aren’t the miners’ deaths mentioned in Dr. Shi’s paper? This is brought up again when she calls the mine abandoned.
Why Lie About the State of the Mine as Being Abandoned?
Why did the Shi lab not acknowledge the miners’ deaths in any paper describing samples taken from the mine (Ge et al., 2016 and P. Zhou et al., 2020)? Why in the title of the Ge at al. 2016 paper did the Shi lab call it an “abandoned” mine? – Independent Science News
Why Search the Mojiang Mine Four Times?
All of this begs the question of why the Shi lab, which has no interest in fungi but a great interest in SARS-like bat coronaviruses, also searched the Mojiang mine for bat viruses on four separate occasions between August 2012 and July 2013, even though the mine is a 1,000 Km from Wuhan (Ge et al., 2016). – Independent Science News
The answer is simple. Shi and her colleagues knew the miners were infected with a virus and were looking for the origin of that virus.
Why Search the Mojiang Mine?
These collecting trips began while some of the miners were still hospitalised. We suggest, first, that inside the miners RaTG13 (or a very similar virus) evolved into SARS-CoV-2, an unusually pathogenic coronavirus highly adapted to humans.
Second, that the Shi lab used medical samples taken from the miners and sent to them by Kunming University Hospital for their research. It was this human-adapted virus, now known as SARS-CoV-2, that escaped from the WIV in 2019. – Independent Science News
Under this hypothesis, the WIV had the SARS-CoV-2 virus already for between 6 and 7 years before it leaked from the lab.
Why Change the Name of the Virus from BtCoV/4991
When they published the sequence of RaTG13 in Feb. 2020, why did the Shi lab provide a new name (RaTG13) for BtCoV/4991 when they had by then cited BtCoV/4991 twice in publications and once in a genome sequence database and when their sequences were from the same sample and 100% identical (P. Zhou et al., 2020)?
If it was just a name change, why no acknowledgement of this in their 2020 paper describing RaTG13 (Bengston, 2020)?
These strange and unscientific actions have obscured the origins of the closest viral relatives of SARS-CoV-2, viruses that are suspected to have caused a COVID-like illness in 2012 and which may be key to understanding not just the origin of the COVID-19 pandemic but the future behaviour of SARS-CoV-2.
These are not the only questionable actions associated with the provenance of samples from the mine. There were five scientific publications that very early in the pandemic reported whole genome sequences for SARS-CoV-2 (Chan et al., 2020; Chen et al., 2020; Wu et al., 2020; P. Zhou et al., 2020; Zhu et al., 2020). Despite three of them having experienced viral evolutionary biologists as authors (George Gao, Zheng-li Shi and Edward Holmes) only one of these (Chen et al., 2020) succeeded in identifying the most closely related viral sequence by far: BtCoV/4991 a viral sequence in the possession of the Shi lab at the WIV that differed from SARS-CoV-2 by just 5 nucleotides.
Why Can’t the US Get Access to Dr. Shi’s Lab Notebooks?
As we noted in our earlier article, the most important of the questions surrounding the origins of SARS-CoV-2 could potentially be resolved by a simple examination of the complete lab notebooks and biosafety records of relevant researchers at the WIV. Now that a credible and testable lab escape hypothesis exists this task becomes potentially much easier. This moment thus represents an opportune one to renew that call for an independent and transparent investigation of the WIV.
Why Has No Independent Scientific Investigation Been Performed?
In requesting an investigation we are aware that no scientific institution anywhere has made a comparable request. We believe that this failure undermines public trust in a “scientific response” to the pandemic. Instead, the scientific establishment has labeled the lab escape theory a “rumor“, an “unverified theory” and a “conspiracy” when its proper name is a hypothesis. By taking this stance the scientific establishment has given the unambiguous message that scientists who take the possibility of a lab origin seriously are jeopardising their careers. Thus, while countless scientific publications on the pandemic assert in their introductions that a zoonotic origin for SARS-CoV-2 is a matter of fact or near-certainty (and Andersen et al has 860 citations as of July 14th), there is still not one published scientific paper asserting that a lab escape is even a credible hypothesis that deserves investigation.
Anyone who doubts this pressure should read the interview with Birger Sørensen in Norway’s Minerva magazine in which Sørensen discusses the “reluctance” of journals to publish his assessment that the existence of a virus that is “exceptionally well adjusted to infect humans” is “suspicious” and “cannot have evolved naturally”. The source of this reluctance, says Sørensen, is not rationality or scientific evidence. It results from conflicts of interest.
This mirrors our experience. To find genuinely critical analysis of COVID-19 origin theories one has to go to Twitter, blog posts, and preprint servers. The malaise runs deep when even scientists start to complain that they don’t trust science.
We nevertheless hope that journalists will investigate some of the conflicts of interest that are keeping scientists and institutions from properly investigating the lab escape hypothesis. – Independent Science News
The Impossibility of the Zoonotic Hypothesis for SARS-CoV-2
The final point that we would like to make is that the principal zoonotic origin thesis is the one proposed by Andersen et al. Apart from being poorly supported this thesis is very complex. It requires two species jumps, at least two recombination events between quite distantly related coronaviruses and the physical transfer of a pangolin (having a coronavirus infection) from outside China (Andersen et al., 2020). Even then it provides no logical explanation of the adaptedness of SARS-CoV-2 across its whole genome or why the virus emerged in Wuhan.
By contrast, our MMP proposal requires only the one species jump, which is documented in the Master’s thesis. Although we do not rule out a possible role for mixed infections in the lungs of the miners, nor the possibility of recombination between closely related variants in those lungs, nor the potential acquisition of the furin site from a host mRNA, only mutation was needed to derive SARS-CoV-2 from RaTG13. Hence our attention earlier to the figure from P. Zhou et al., 2020 – Independent Science News
