China said giving coronavirus vaccines still being tested to hundreds of thousands of people outside of clinical trials is justified given the risk of Covid-19 returning through its borders and the lack of any significant side-effects so far from the shots.
In July, the country authorized the emergency use of three vaccines developed by local firms China National Biotec Group Co. and Sinovac Biotech Ltd. to frontline workers, including medical staff treating virus patients, and to border officials.
