HONG KONG (AP) — Hong Kong began administering its first COVID-19 vaccines to the public, kicking off its program offering free vaccinations to all 7.5 million residents. People age 60 and older and health care workers are among the some 2.4 million people currently prioritized to receive vaccines at community centers and outpatient clinics across Hong Kong. The government said registrations for the first two weeks of the program are full. Participants so far will be receiving the vaccine by Chinese biopharmaceutical firm Sinovac. A million doses arrived in the city last week, and Hong Kong leader Carrie Lam and other top government officials were vaccinated first in a bid to bolster confidence in the program.
