China has started inoculating some key groups with COVID-19 vaccines in this winter-spring period, which is expected to lower the risks of domestic outbreaks of the epidemic.

The vaccines have been given to priority groups, including frontline customs inspectors of imported cold-chain goods and personnel working in the overseas and domestic transportation sector.

A total of 73,537 people in Beijing have received COVID-19 vaccines at 220 inoculation venues, and Beijing will complete the inoculation for key groups before the Spring Festival, which falls on Feb 12 this year.
