Coronavirus
There's something wrong with the reported numbers: 32/160 = 20%''In the trials, more than 12,000 health workers were vaccinated in two doses.
It was noted that COVID-19 was observed in 288 of the participants in the trial, of which 128 were given the actual vaccine formula and 160 were given a placebo (fake formula).
The Butantan Institute reported yesterday that the overall effectiveness of Sinovac’s CoronaVac vaccine was 50.38%.''
