BEIJING (AP) — China’s top disease control official, in a rare acknowledgement, said current vaccines offer low protection against the coronavirus and mixing them is among strategies being considered to boost their effectiveness.
China has distributed hundreds of millions of doses of domestically made vaccines abroad and is relying on them for its own mass immunization campaign.
But the director of the Chinese Center for Disease Control and Prevention, Gao Fu, said at a conference Saturday their efficacy rates needed improving.
“We will solve the issue that current vaccines don’t have very high protection rates,” Gao said in a presentation on Chinese COVID-19 vaccines and immunization strategies at a conference in the southwestern city of Chengdu. “It’s now under consideration whether we should use different vaccines from different technical lines for the immunization process.”
