Mainland China has reported 11 new COVID-19 cases, down from 12 a day earlier and the lowest daily increase since December 16.
The National Health Commission said in a statement on Sunday only one of the new cases was locally transmitted, located in China's northeastern Jilin province.
The number of new asymptomatic cases, which China does not classify as confirmed cases, stood at 13, including 11 imported cases.
The total number of confirmed COVID-19 cases in mainland China now stands at 89,692, while the death toll remained unchanged at 4636.
Sinovac Biotech said on Saturday its vaccine had been formally approved for use by the general public by China's medical products regulator.
It marked the second vaccine given universal approval after a shot developed by a Beijing institute affiliated to state-owned China National Pharmaceutical Group (Sinopharm) was approved in December.
Prior to the approvals, both vaccines have already been used in China's vaccination program mainly targeting key groups deemed to be at higher risk of exposure to the virus.
Indonesia, Turkey, Brazil, Chile, Colombia, Uruguay, and Laos have granted emergency authorisations for the CoronaVac vaccine developed by Sinovac Life Sciences, Sinovac said in a news release.
The approval is based on the two-month results from late-stage clinical trials overseas, from which the final analysis data has not yet been obtained, Sinovac said.
