Covid-19 Cooked Up in a Lab By Brian Simpson

     Here is the latest case that Covid-19, the New World Order virus, was cooked up in a lab. This case is made by two virologists:

“But one other troubling possibility must be dispensed with. It follows from the fact that the epicentre city, Wuhan (pop. 11 million), happens to be the global epicentre of bat coronavirus research (e.g. Hu et al., 2017).
Prompted by this proximity, various researchers and news media, prominently the Washington Post, and with much more data Newsweek, have drawn up a prima facie case that a laboratory origin is a strong possibility (Zhan et al., 2020; Piplani et al., 2020). That is, one of the two labs in Wuhan that has worked on coronaviruses accidentally let a natural virus escape; or, the lab was genetically engineering (or otherwise manipulating) a Sars-CoV-2-like virus which then escaped. Unfortunately, in the US at least, the question of the pandemic’s origin has become a political football; either an opportunity for Sinophobia or a partisan “blame game“. But the potential of a catastrophic lab release is not a game and systemic problems of competence and opacity are certainly not limited to China (Lipsitch, 2018). The US Department of Homeland Security (DHS) is currently constructing a new and expanded national Bio and Agro-defense facility in Manhattan, Kansas. DHS has estimated that the 50-year risk (defined as having an economic impact of $9-50 billion) of a release from its lab at 70%. When a National Research Council committee inspected these DHS estimates they concluded “The committee finds that the risks and costs could well be significantly higher than that“.

A subsequent committee report (NAP, 2012) continued:

“the committee was instructed to judge the adequacy and validity of the uSSRA [updated Site-Specific Risk Assessment]. The committee has identified serious concerns about (1) the misapplication of methods used to assess risk, (2) the failure to make clear whether and how the evidence used to support risk assessment assumptions had been thoroughly reviewed and adequately evaluated, (3) the limited breadth of literature cited and the misinterpretation of some of the significant supporting literature, (4) the failure to explain the criteria used to select assumptions when supporting literature is conflicting, (5) the failure to consider important risk pathways, and (6) the inadequate treatment of uncertainty. Those deficiencies are not equally problematic, but they occur with sufficient frequency to raise doubts about the adequacy and validity of the risk results presented. In most instances (e.g., operational activities at the NBAF), the identified problems lead to an underestimation of risk; in other instances (e.g., catastrophic natural hazards), the risks may be overestimated. As a result, the committee concludes that the uSSRA is technically inadequate in critical respects and is an insufficient basis on which to judge the risks associated with the proposed NBAF in Manhattan, Kansas.”

China, meanwhile, having opened its first in Wuhan in 2018, is planning to roll out a national network of BSL-4 labs (Yuan, 2019). Like many other countries, it is investing significantly in disease surveillance and collection of viruses from wild animal populations and in high-risk recombinant virus research with Potential Pandemic Pathogens (PPPs). On May 4th, nations and global philanthropies, meeting in Brussels, committed $7.4 billion to future pandemic preparedness. But the question hanging over all such investments is this: the remit of the Wuhan lab at the centre of the accidental release claims is pandemic preparedness. If the COVID-19 pandemic began there then we need to radically rethink current ideas for pandemic preparation globally. Many researchers already believe we should, for the sake of both safety and effectiveness (Lipsitch and Galvani, 2014; Weiss et al., 2015; Lipsitch, 2018). The worst possible outcome would be for those donated billions to accelerate the arrival of the next pandemic. The essence of the lab escape theory is that Wuhan is the site of the Wuhan Institute of Virology (WIV), China’s first and only Biosafety Level 4 (BSL-4) facility. (BSL-4 is the highest pathogen security level). The WIV, which added a BSL-4 lab only in 2018, has been collecting large numbers of coronaviruses from bat samples ever since the original SARS outbreak of 2002-2003; including collecting more in 2016 (Hu, et al., 2017; Zhou et al., 2018). Led by researcher Zheng-Li Shi, WIV scientists have also published experiments in which live bat coronaviruses were introduced into human cells (Hu et al., 2017). Moreover, according to an April 14 article in the Washington Post, US Embassy staff visited the WIV in 2018 and “had grave safety concerns” about biosecurity there. The WIV is just eight miles from the Huanan live animal market that was initially thought to be the site of origin of the COVID-19 pandemic. Wuhan is also home to a lab called the Wuhan Centers for Disease Prevention and Control (WCDPC). It is a BSL-2 lab that is just 250 metres away from the Huanan market. Bat coronaviruses have in the past been kept at the Wuhan WCDPC lab. Thus the lab escape theory is that researchers from one or both of these labs may have picked up a Sars-CoV-2-like bat coronavirus on one of their many collecting (aka “virus surveillance”) trips. Or, alternatively, a virus they were studying, passaging, engineering, or otherwise manipulating, escaped.

Scientific assessments of the lab escape theory
On April 17 the Australian Science Media Centre asked four Australian virologists: “Did COVID-19 come from a lab in Wuhan?“ Three (Edward Holmes, Nigel McMillan and Hassan Vally) dismissed the lab escape suggestion and Vally simply labeled it, without elaboration, a “conspiracy”. The fourth virologist interviewed was Nikolai Petrovsky of Flinders University. Petrovsky first addressed the question of whether the natural zoonosis pathway was viable. He told the Media Centre:

“no natural virus matching to COVID-19 has been found in nature despite an intensive search to find its origins.” That is to say, the idea of an animal intermediate is speculation. Indeed, no credible viral or animal host intermediaries, either in the form of a confirmed animal host or a plausible virus intermediate, has to-date emerged to explain the natural zoonotic transfer of Sars-CoV-2 to humans (e.g. Zhan et al., 2020). In addition to Petrovsky’s point, there are two further difficulties with the natural zoonotic transfer thesis (apart from the weak epidemiological association between early cases and the Huanan “wet” market). The first is that researchers from the Wuhan lab travelled to caves in Yunnan (1,500 Km away) to find horseshoe bats containing SARS-like coronaviruses. To-date, the closest living relative of Sars-CoV-2 yet found comes from Yunnan (Ge et al., 2016). Why would an outbreak of a bat virus therefore occur in Wuhan? Moreover, China has a population of 1.3 billion. If spillover from the wildlife trade was the explanation, then, other things being equal, the probability of a pandemic starting in Wuhan (pop. 11 million) is less than 1%.

Zheng-Li Shi, the head of bat coronavirus research at WIV, told Scientific American as much:
“I had never expected this kind of thing to happen in Wuhan, in central China.” Her studies had shown that the southern, subtropical provinces of Guangdong, Guangxi and Yunnan have the greatest risk of coronaviruses jumping to humans from animals—particularly bats, a known reservoir. If coronaviruses were the culprit, she remembers thinking, “Could they have come from our lab?” Wuhan, in short, is a rather unlikely epicentre for a natural zoonotic transfer. In contrast, to suspect that Sars-CoV-2 might have come from the WIV is both reasonable and obvious. Was Sars-CoV-2 created in a lab? In his statement, Petrovsky goes on to describe the kind of experiment that, in principle, if done in a lab, would obtain the same result as the hypothesised natural zoonotic transfer–rapid adaptation of a bat coronavirus to a human host. “Take a bat coronavirus that is not infectious to humans, and force its selection by culturing it with cells that express human ACE2 receptor, such cells having been created many years ago to culture SARS coronaviruses and you can force the bat virus to adapt to infect human cells via mutations in its spike protein, which would have the effect of increasing the strength of its binding to human ACE2, and inevitably reducing the strength of its binding to bat ACE2. Viruses in prolonged culture will also develop other random mutations that do not affect its function. The result of these experiments is a virus that is highly virulent in humans but is sufficiently different that it no longer resembles the original bat virus. Because the mutations are acquired randomly by selection there is no signature of a human gene jockey, but this is clearly a virus still created by human intervention.” In other words, Petrovsky believes that current experimental methods could have led to an altered virus that escaped.

Passaging, GOF research, and lab escapes
The experiment mentioned by Petrovsky represents a class of experiments called passaging. Passaging is the placing of a live virus into an animal or cell culture to which it is not adapted and then, before the virus dies out, transferring it to another animal or cell of the same type. Passaging is often done iteratively. The theory is that the virus will rapidly evolve (since viruses have high mutation rates) and become adapted to the new animal or cell type. Passaging a virus, by allowing it to become adapted to its new situation, creates a new pathogen. The most famous such experiment was conducted in the lab of Dutch researcher Ron Fouchier. Fouchier took an avian influenza virus (H5N1) that did not infect ferrets (or other mammals) and serially passaged it in ferrets. The intention of the experiment was specifically to evolve a PPP. After ten passages the researchers found that the virus had indeed evolved, to not only infect ferrets but to transmit to others in neighbouring cages (Herfst et al., 2012). They had created an airborne ferret virus, a Potential Pandemic Pathogen, and a storm in the international scientific community. The second class of experiments that have frequently been the recipients of criticism are GOF experiments. In GOF research, a novel virus is deliberately created, either by in vitro mutation or by cutting and pasting together two (or more) viruses. The intention of such reconfigurations is to make viruses more infectious by adding new functions such as increased infectivity or pathogenicity. These novel viruses are then experimented on, either in cell cultures or in whole animals. These are the class of experiments banned in the US from 2014 to 2017. Some researchers have even combined GOF and passaging experiments by using recombinant viruses in passaging experiments (e.g. Sheahan et al., 2008). Such experiments all require recombinant DNA techniques and animal or cell culture experiments. But the very simplest hypothesis of how Sars-CoV-2 might have been caused by research is simply to suppose that a researcher from the WIV or the WCDCP became infected during a collecting expedition and passed their bat virus on to their colleagues or family. The natural virus then evolved, in these early cases, into Sars-CoV-2. For this reason, even collecting trips have their critics. Epidemiologist Richard Ebright called them “the definition of insanity“. Handling animals and samples exposes collectors to multiple pathogens and returning to their labs then brings those pathogens back to densely crowded locations.

Was the WIV doing experiments that might release PPPs?
Since 2004, shortly after the original SARS outbreak, researchers from the WIV have been collecting bat coronaviruses in an intensive search for SARS-like pathogens (Li et al., 2005). Since the original collecting trip, many more have been conducted (Ge et al., 2013; Ge et al., 2016; Hu et al., 2017; Zhou et al., 2018). Petrovsky does not mention it but Zheng-Li Shi’s group at the WIV has already performed experiments very similar to those he describes, using those collected viruses. In 2013 the Shi lab reported isolating an infectious clone of a bat coronavirus that they called WIV-1 (Ge et al., 2013). WIV-1 was obtained by introducing a bat coronavirus into monkey cells, passaging it, and then testing its infectivity in human (HeLa) cell lines engineered to express the human ACE2 receptor (Ge et al., 2013). In 2014, just before the US GOF research ban went into effect, Zheng-Li Shi of WIV co-authored a paper with the lab of Ralph Baric in North Carolina that performed GOF research on bat coronaviruses (Menachery et al., 2015). In this particular set of experiments the researchers combined “the spike of bat coronavirus SHC014 in a mouse-adapted SARS-CoV backbone” into a single engineered live virus. The spike was supplied by the Shi lab. They put this bat/human/mouse virus into cultured human airway cells and also into live mice. The researchers observed “notable pathogenesis” in the infected mice (Menachery et al. 2015). The mouse-adapted part of this virus comes from a 2007 experiment in which the Baric lab created a virus called rMA15 through passaging (Roberts et al., 2007). This rMA15 was “highly virulent and lethal” to the mice. According to this paper, mice succumbed to “overwhelming viral infection”.

In 2017, again with the intent of identifying bat viruses with ACE2 binding capabilities, the Shi lab at WIV reported successfully infecting human (HeLa) cell lines engineered to express the human ACE2 receptor with four different bat coronaviruses. Two of these were lab-made recombinant (chimaeric) bat viruses. Both the wild and the recombinant viruses were briefly passaged in monkey cells (Hu et al., 2017). Together, what these papers show is that: 1) The Shi lab collected numerous bat samples with an emphasis on collecting SARS-like coronavirus strains, 2) they cultured live viruses and conducted passaging experiments on them, 3) members of Zheng-Li Shi’s laboratory participated in GOF experiments carried out in North Carolina on bat coronaviruses, 4) the Shi laboratory produced recombinant bat coronaviruses and placed these in human cells and monkey cells. All these experiments were conducted in cells containing human or monkey ACE2 receptors. The overarching purpose of such work was to see whether an enhanced pathogen could emerge from the wild by creating one in the lab. (For a very informative technical summary of WIV research into bat coronaviruses and that of their collaborators we recommend this post, written by biotech entrepreneur Yuri Deigin). It also seems that the Shi lab at WIV intended to do more of such research. In 2013 and again in 2017 Zheng-Li Shi (with the assistance of a non-profit called the EcoHealth Alliance) obtained a grant from the US National Institutes of Health (NIH). The most recent such grant proposed that:

“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” (NIH project #5R01Al110964-04). It is hard to overemphasize that the central logic of this grant was to test the pandemic potential of SARS-related bat coronaviruses by making ones with pandemic potential, either through genetic engineering or passaging, or both. Apart from descriptions in their publications we do not yet know exactly which viruses the WIV was experimenting with but it is certainly intriguing that numerous publications since Sars-CoV-2 first appeared have puzzled over the fact that the SARS-CoV-2 spike protein binds with exceptionally high affinity to the human ACE2 receptor “at least ten times more tightly” than the original SARS (Zhou et al., 2020; Wrapp et al., 2020; Wan et al., 2020; Walls et al., 2020; Letko et al., 2020). This affinity is all the more remarkable because of the relative lack of fit in modelling studies of the SARS-CoV-2 spike to other species, including the postulated intermediates like snakes, civets and pangolins (Piplani et al., 2020). In this preprint these modellers concluded “This indicates that SARS-CoV-2 is a highly adapted human pathogen”. Given the research and collection history of the Shi lab at WIV it is therefore entirely plausible that a bat SARS-like cornavirus ancestor of Sars-CoV-2 was trained up on the human ACE2 receptor by passaging it in cells expressing that receptor. [On June 4 an excellent article in the Bulletin of the Atomic Scientists went further. Pointing out what we had overlooked, that the Shi lab also amplified spike proteins of collected coronaviruses, which would make them available for GOF experimentation (Ge et al., 2016).]”

     But, if the lab escape hypothesis is entertained, it must explain how the virus escaped from a presumably biohazard secure lab. Accidents and human error are the most likely causes the article says, and there were doubts abut the safety procedures of the Wuhan lab. The possibility of a deliberated release, was not discussed, but it   would also be consistent with China’s cover up, which we have documented in a number of articles at this site, and better coheres with the evidence than the accident escape hypothesis, where China would gain nothing by acting to cover up. There is something very fishy, or batty, about this whole affair, and it looks like being another 9/11, as the world goes through the second round, and maybe even a new pneumonia pandemic, sure to be released to the West, because, that is just globalism.
