A city in China’s Zhejiang province will offer experimental coronavirus vaccines to its residents, as China broadens an emergency use programme to people in non-priority groups.

Residents aged between 18 and 59 in the city of Shaoxing, who are not in priority groups, can apply online for inoculation, the city’s health commission said on its WeChat account. It did not name the vaccine, say when inoculation would start or how many doses would be offered.

Shaoxing residents that choose to be inoculated will need to give reasons for wanting the vaccine on their applications and will be charged 400 yuan ($60) for two doses, with an additional inoculation fee of 28 yuan per dose, the city said.
