Turkish trials found China’s Sinovac inoculation to be 83.5% effective against the coronavirus, a level of protection that’s lower than the country’s initial predictions but significantly above Brazilian estimates.

The CoronaVac shot made by Sinovac Biotech Ltd. was 100% effective in preventing hospitalization, according to the Phase 3 trials by the prestigious Hacettepe University in Ankara, state-run Anadolu Agency reported.
