Two new scientific papers and Biden's intel inquiry are undercutting the lab leak theory for the pandemic's origin.
As with chloroquine, there’s no reliable evidence that ivermectin works against COVID-19. You can’t censor what doesn’t exist.
Scientists haven’t yet detected the virus in live animals thought to be likely direct or intermediate hosts before its jump to humans, including bats, raccoon dogs or palm civets, but it’s not unusual for that sort of investigation to take years. “We know it can jump species fairly easily,” Rasmussen says. Moreover, the appearance of multiple variants such as the Delta variant, with improving transmissibility, suggests that it was not ideally suited to human hosts at first.
Chief among these is the so-called furin cleavage site, where an enzyme breaks the virus’ spike in two to enable it to better penetrate and therefore infect human cells. Some lab leak proponents assert that the furin cleavage site is too novel to have occurred naturally.
