To review, in an effort to research what makes Omicron so transmissible - and funded in part by grants from the NIH and Anthony Fauci's NIAID - a team of 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.

The authors speculate that their chimeric strain is unlikely to be as deadly in humans as it was in the mice because the specific breed used in testing are more susceptible to severe Covid.

Gain of Function?

"The research is a clear example of gain of function research of concern and enhanced potential pandemic pathogen (ePPP) research," said Dr Richard Ebright, a chemist at Rutgers University in New Brunswick, New Jersey, adding "'It is especially concerning that this new US-government ePPP research - like the previous US-government ePPP research on chimeric SARS-related coronaviruses at Wuhan Institute of Virology that may have caused the pandemic - appears not to have undergone the prior risk-benefit review mandated under US-government policies."
