Shenzhen's free COVID-19 vaccinations, starting this week for high-risk groups, are warmly welcomed by locals.

Workers related to frontline epidemic control, healthcare service, public transport and cross-border logistics, as well as people working or studying overseas, can apply for the shots, paid by the local government. 

The daily quota is 300 to 500 for now, and the total number of applications has exceeded the limitation.

At the Dachong Community Health Center of Nanshan District Medical Group Headquarters, one of the city's five vaccination centers, more than a dozen medical staff were onsite to check recipients' information, set up personal health files, give the injection and guide them to set a schedule for the second shot.

People were waiting in line in an orderly way under their guidance. It took about 6 to 8 minutes for each injection, and the recipients could leave after 30 minutes of observation.
