Daily US Times: China’s top disease control official acknowledged a rare admission of the weakness of Chinese Covid-19 vaccines, adding that the vaccine’s effectiveness is low and the government is considering mixing them to get a boost.

At a conference Saturday in the southwestern city of Chengdu, the director of the China Centers for Disease Control, Gao Fu, said that Chinese vaccines “don’t have very high protection rates.”

China has distributed hundreds of millions of doses abroad while trying to promote doubt about the effectiveness of the Pfizer-BioNTech’s coronavirus vaccine made using the previously experimental messenger RNA, or mRNA, process.

Gao said: “It’s now under formal consideration whether we should use different vaccines from different technical lines for the immunization process,”

Officials at a news conference Sunday did not respond directly to questions about the country’s top disease control expert’s comment or possible changes in official plans.

But another Chinese CDC official said developers are working on mRNA-based vaccines.

An official named Wang Huaqing said “The mRNA vaccines developed in our country have also entered the clinical trial stage.” He gave no timeline for it.

Experts say equential immunization or mixing vaccines, might boost effectiveness. Researchers in Britain are studying a possible combination of the traditional AstraZeneca vaccine and Pfizer-BioNTech’s vaccine.

The Covid-19 pandemic, which began in central China in late 2019, marks the first time the Chinese drug industry has played a role in responding to a global health emergency.
