Chinese regulators have approved the country's first homegrown coronavirus vaccine, developed by state-owned pharmaceutical giant Sinopharm, officials announced Thursday.
The approval comes a day after Sinopharm said its vaccine is 79.34% effective, citing interim analysis of Phase 3 clinical trials.
China has drastically scaled up its vaccine emergency use program in recent weeks. Since December 15, it has administered more than 3 million vaccine doses on "key groups" in the population, Zeng Yixin, vice-minister of China's National Health Commission, said at a news conference Thursday. That's on top of the 1.5 million doses administered on "high-risk groups" by the end of November, Zeng added.
Among those inoculated, fewer than 0.1% developed a light fever, and about two people per million developed "relative serious adverse reactions" such as allergies, according to Zeng.
