We are now three years after the COVID-19 apocalypse began, and the CDC and WHO still refuse to acknowledge that the virus was created in and escaped from the Wuhan Institute of Virology (WIV). But they, along with all our institutions, have lied so often and so egregiously that 72% of the public doesn’t believe them. If nothing else, that is a very positive sign.

The evidence for the lab leak is as overwhelming as the evidence for a zoonotic origin is non-existent. For anyone trained in the art of biology to deny the lab origin betrays either deceit or, worse, willful ignorance.

Here I examine just three facts that together, if not singularly, prove dispositively that SARS-CoV-2 was a man-made lab creation. Not least of which is that they told us exactly what they were going to do.

Viruses are obligate intracellular parasites composed of genetic material—codons that specify the specific amino acids (there are 20) used to construct proteins—that hijack the machinery of the cell to produce more viruses.

This is no easy task and, to do so, viruses are extremely specialized and highly specific to their host. Viruses can and do randomly mutate; that is, they undergo random changes to their genetic code that can give them fitness in another host, albeit infrequently. Once they get a foothold in a new host, they continue to evolve by natural selection, making themselves better adapted to reproduce in their new host.

One key factor for a virus to be successful in a new host is to have a highly tuned receptor binding domain (RBD). The RBD allows the virus to recognize the host cell, bind to it, and get inside. In SARS, the RBD is 201 codons long. Jesse Bloom of Caltech analyzed the RBD codon sequence to determine what sequence would maximize binding to human cells. Of the 4000 possible combinations, SARS-CoV-2 showed up on day one over 99% optimized—only 21 codons short of perfection. As a verification of the validity of Bloom’s work, one of those 21 codons was later found in the more contagious Omicron variant to have mutated to Bloom’s prediction.

To put this in context, when SARS-CoV-1 crossed over to humans, its RBD was only 15% optimized, and there is a long chain of documented mutations in its RBD that eventually gave it the ability to be transmitted from human to human. How could SARS-CoV-2 have been so pre-perfected?

Ralph Baric of UNC, a co-author of several papers with the WIV on bat coronavirus, experimented with transgenic mice — mice genetically altered to have humanized lung tissue — as early as 2005 to demonstrate they could be infected with human coronaviruses. In his statement before Congress, Dr. Steven Quay testified that “the WIV has acknowledged that for several years they’ve worked with humanized mice developed in Dr. Ralph Baric’s laboratory.” 

Humanized mice are the perfect vehicle for researchers to develop viruses optimized for human infectivity. Quay continued, “a commonly used gain-of-function method to optimize the COVID virus would have been by serial passage in a laboratory on a humanized, genetically modified mouse that can develop a human-like pneumonia. You infect the mice, wait a week or so, and then recover the virus from the sickest mice. Then you repeat. In a matter of weeks this directed evolution will produce a virus that can kill every humanized mouse.”

Once bound, there is still a highly complicated molecular ballet the virus must perform to gain entry. One vital step is the cleavage of the spike protein, which activates viral fusion with the cell membrane. Many viruses, including the deadliest, like Ebola, have furin cleavage sites (FCS) in their spike proteins to facilitate cleavage. However, in the clade of viruses containing SARS-CoV-2, Sarbecoviruses, none had an FCS…until now.
