WHO and FDA are shit , they are bitches of the rich. It was due to negligence of who we are in this state , and they will never be happy with a cure or vaccine coming from non west which doesn't benefit their interests .
Russia in 1969 did the same with polio vaccine and it succeded
Phase 1 and 2 already tested safety of vaccine , phase 3 is to check the effectiveness which is not completed .
Even if people gets corona after the vaccine it will be mild because they have produced enough antibodies.
Also it's a dead virus vaccine so the virus won't multiply there is less...
