BEIJING (AP) — In a rare admission of the weakness of Chinese coronavirus vaccines, the country’s top disease control official says their effectiveness is low and the government is considering mixing them to give them a boost. The director of the China Centers for Disease Control, Gao Fu, says Chinese vaccines don’t have very high protection rates. Gao was speaking at a conference in the southwestern city of Chengdu. Beijing has distributed hundreds of millions of doses in other countries while also trying to promote doubt about the effectiveness of Western vaccines. Gao says it was under formal consideration whether to mix different vaccines.
