"How many times did virologists say they were not making chimeric SARS viruses more deadly?"
By Tyler Durden: Researchers at Boston University have created a new strain of Covid-19 that has an 80% kill rate in humanized mice.

In an effort to research what makes Omicron so transmissible - and funded in part by grants from the NIH and Anthony Fauci's NIAID, the researchers cobbled the Omicron spike protein to the original strain of Covid-19. The resulting virus was five times more infectious than Omicron.
"The
Omicron spike (S) protein, with an unusually large number of mutations,
is considered the major driver of these phenotypes. We generated chimeric recombinant SARS-CoV-2 encoding the S gene of Omicron in the backbone of an ancestral SARS-CoV-2 isolate and compared this virus with the naturally circulating Omicron variant," reads the pre-print.
