jerzmacowon Lab crafts mutant Covid-19 strain with 100% kill streak in humanized mice

From a layman's perspective, the GOF research that may or may not have caused covid in the first place, never actually yeiled anything useful for the pandemic. I'm pretty pro research, but I haven't seen anything good come from GOF.
