In a rare admission of the weakness of coronavirus vaccines developed in China, the country's top disease control official says their effectiveness is low and the government is considering mixing them to get a boost.
China's vaccines "don't have very high protection rates," Gao Fu, the director of China's Centers for Disease Control, said at a conference Saturday in the southwestern city of Chengdu.
Beijing has distributed hundreds of millions of doses abroad while trying to promote doubt about the effectiveness of the Pfizer-BioNTech vaccine made using the previously experimental messenger RNA, or mRNA, process.
"It's now under formal consideration whether we should use different vaccines from different technical lines for the immunization process," Gao said.
