Study Determines China’s Sinopharm COVID Vaccine Up to 78% Effective

A Journal of the American Medical Association study found that two vaccines from the China-owned company Sinopharm are 73% and 78% effective against COVID-19, the Associated Press reported.

Distribution of the two vaccines has begun in many countries, and the World Health Organization has authorized emergency use of one of the vaccines. The study's conclusion on the vaccines' effectiveness aligns with previous reports from Sinopharm.

Sinopharm researchers and Middle East partners conducted the trial using both vaccines and a placebo with over 40,000 participants across Bahrain, the United Arab Emirates, Egypt and Jordan. Jin Dong-yan, a University of Hong Kong medical professor separate from the trial, said that the study's results were unsurprising but still don't totally negate potential drawbacks.
