CoronaVac, the Covid-19 vaccine developed by China’s Sinovac Biotech, was found to be just 50.4% effective in a Brazilian trial, much lower than 78% as touted earlier. Brazil’s Butantan Institute, which was the first to complete late-stage trial of the vaccine, said the vaccine’s overall efficacy rate fell to 50.4% when including ’very mild’ cases that did not require medical assistance.
Don't forget that the CCP vaccine has 73 known side effects too.

1 out of 2 will be able to contract the Coronavirus even after both are vaccinated against it with china's mickey mouse "quality" level vaccine.
