China focuses vaccination on key groups over winter, spring

China will focus first on vaccinating high-risk groups over the winter and spring before widening the inoculation to the general public, a senior health official said on Saturday.

Zeng Yixin, vice minister of China’s National Health Commission (NHC) and director of the State Council’s vaccine R&D working group, warned that China’s COVID-19 prevention efforts were under increasing pressure as temperatures fall.

“During the winter and spring seasons, carrying out novel coronavirus vaccination work among some key population groups is of great significance to epidemic prevention,” he said

China aims to actively build group immunity, and the vaccination of high-risk groups – which include workers in the cold chain industry, customs, healthcare, markets and public transport. This is just the first part of a “step-by-step programme”, he added.

China has included two candidate vaccines from Sinopharm and one from Sinovac Biotech Ltd in an emergency-use programme launched in July, targeting specific high-infection risk groups such as medical workers and border inspectors.

It has also approved a vaccine from CanSino Biologics Inc for military use but has not approved any vaccine for use among the general public.

China is planning to vaccinate as many as 50 million people before the start of the Lunar New Year holiday in Feb. 2021, reports said.

It said that Beijing would distribute 100 million doses of vaccines made by Sinopharm and Sinovac Biotech.

Mao Junfeng, an official with China’s industry ministry, said that the firms had already completed their “capacity construction tasks” and would be capable of meeting demand from key population groups. He did not say how many vaccines would be needed in total.

Zheng Zhongwei, the NHC official heading China’s COVID-19 vaccine development team, said China had administered more than 1 million emergency doses to members of high-risk groups since July and “no serious adverse reactions” had been detected so far.

“For the vaccines where we are moving quite fast, the number of cases required for the interim stage of Phase III clinical trials have already been obtained,” Zheng said, without elaborating on specific products.

’’Data has been submitted to the medical products regulator, which will approve the vaccines if they meet the necessary conditions,’’ he added.
