it kills 80% of mice. did you read the part where the original variant kills 100% of mice.
now another part is the study hasn't been peer reviewed yet. so until it is and if confirmed, it is 20% less virulent to mice.
and considering that omnicron was not even close to kill as many humans as rats. well I'll wait.

Did not read that but saw this in the article which is why it was alarming:
"80 percent of mice died from the new man-made Covid strain, while none died from the milder Omicron variant alone, researchers at Boston University's National Emerging Infectious Diseases Laboratories found"
It's the new S variant coming to a lockdown near you soon..when needed.
