Chinese virologist Dr. Li-Meng Yan publishes proof and evidence COVID-19 was created in Wuhan Lab; joins Twitter | Tech News

On Saturday, we wrote about Chinese virologist Dr. Li-Meng Yan after she appeared last week on British television where she claimed SARS-CoV-2, the virus which causes COVID-19, was created by Chinese scientists in a lab. Dr. Yan fled the country and left her job at a prestigious Hong Kong university.

For the first time, Dr. Yan, who is in hiding in an undisclosed location in the United States, posted evidence of her claims that the coronavirus was indeed developed in a Wuhan, China lab. Yesterday, Dr. Yan joined Twitter using the handle: @LiMengYAN119. Dr. Yan already has about 50,000 followers.

On Monday, Dr. Yan tweeted a link to a paper she co-authored with three other Chinese scientists. The paper published at Zenodo.or is titled: “Unusual Features of the SARS-CoV-2 Genome Suggesting Sophisticated Laboratory Modification Rather Than Natural Evolution and Delineation of Its Probable Synthetic Route.

Dr. Yan also posted a link to her credentials on ResearchGate, revealing her former affiliation with the University of Hong Kong and 13 publications that have been cited 557 times.

In the 26-page paper, Dr. Yan and three other Chinese scientists said:

“The evidence shows that SARS-CoV-2 should be a laboratory product created by using bat coronaviruses ZC45 and/or ZXC21 as a template and/or backbone. Building upon the evidence, we further postulate a synthetic route for SARS-CoV-2, demonstrating that the laboratory-creation of this coronavirus is convenient and can be accomplished in approximately six months. Our work emphasizes the need for an independent investigation into the relevant research laboratories. It also argues for a critical look into certain recently published data, which, albeit problematic, was used to support and claim a natural origin of SARS-CoV-2. From a public health perspective, these actions are necessary as knowledge of the origin of SARS-CoV-2 and of how the virus entered the human population are of pivotal importance in the fundamental control of the COVID-19 pandemic as well as in preventing similar, future pandemics.”

Here is the extended punchline:

The receptor-binding motif of SARS-CoV-2 Spike cannot be born from nature and should have been created through genetic engineering.

The Spike proteins decorate the exterior of the coronavirus particles. They play an important role in infection as they mediate the interaction with host cell receptors and thereby help determine the host range and tissue tropism of the virus. The Spike protein is split into two halves (Figure 3). The front or N-terminal half is named S1, which is fully responsible for binding the host receptor. In both SARS-CoV and SARS-CoV-2 infections, the host cell receptor is hACE2. Within S1, a segment of around 70 amino acids makes direct contacts with hACE2 and is correspondingly named the receptor-binding motif (RBM) (Figure 3C). In SARS-CoV and SARS-CoV-2, the RBM fully determines the interaction with hACE2. The C-terminal half of the Spike protein is named S2. The main function of S2 includes maintaining trimer formation and, upon successive protease cleavages at the S1/S2 junction and a downstream S2’ position, mediating membrane fusion to enable cellular entry of the virus.

Below is another interview Dr. Yan had with America Voice on September 10.
