Peru study finds Sinopharm COVID vaccine 50.4% effective against infections

LIMA/BEIJING: A two-dose COVID-19 vaccine from China's Sinopharm was 50.4% effective in preventing infections in health workers in Peru when it was seeing a surge in cases fuelled by virus variants, and booster shots can be considered, a study found.

The study involving Sinopharm's BBIBP-CorV vaccine, which looked at data from February through June at a time when Peru was fighting a brutal second-wave of infections fuelled by the Lambda and Gamma variants of the coronavirus, was conducted on nearly 400,000 frontline health workers in live conditions. Most of the health workers received two doses of the vaccine.
