China approved its first COVID-19 vaccine for general public use Thursday, a shot developed by an affiliate of state-backed pharmaceutical giant Sinopharm, as it braces for greater transmission risks over the winter.

No detailed efficacy data of the vaccine has been publicly released but its developer, Beijing Biological Products Institute, a unit of Sinopharm subsidiary China National Biotec Group (CNBG), said Wednesday its vaccine was 79.34% effective in preventing people from developing the disease based on interim data.

The approval, announced by the National Medical Products Administration, comes after the United Arab Emirates this month became the first country to roll out the vaccine to the public, and as Pakistan announced a 1.2 million dose purchase deal with Sinopharm.
