China approves two more COVID-19 vaccines for wider use

China approved two more COVID-19 vaccines for wider use Thursday, adding to its growing arsenal of shots. The National Medical Products Administration gave conditional approval to a vaccine from CanSino Biologics and a second one from state-owned Sinopharm. Both are already being used among select groups of people under an emergency use authorization. China now has four vaccines to immunize its population. CanSino said its one-shot vaccine candidate is 65.28% effective 28 days after the dose is given. It can be stored at 2 degrees to 8 degrees Celsius, “making it more accessible especially to the regions with underserved public health,” it said in a statement.
