Covid-19 booster shots should become available in China after the country vaccinates more people to provide broader protection against the disease, a senior executive at a Sinopharm unit responsible for developing Covid-19 vaccines told state media.
Zhang Yuntao, vice president at Sinopharm unit China National Biotec Group, said that it is proper to make booster shots available in China after "all people who should be vaccinated are vaccinated", according to an interview with the Global Times.
He said the priority for booster shots should be given to people older than 60 who showed weaker immune responses to vaccines compared with younger people in clinical trials.
