TAIPEI, Taiwan (AP) — China has approved two more COVID-19 vaccines for wider use, adding to its growing arsenal of shots. It 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’s COVID-19 vaccine is the first developed by a Chinese company that requires only one shot. Both vaccines can be stored between 2 degrees and 8 degrees Celsius. Neither company has publicly released final testing data showing safety and efficacy.
