After admitting the low efficacy of vaccines made in mainland China, why did they immediately deny it?

Gao Fu, academician of the Chinese Academy of Sciences and director of the Chinese Center for Disease Control and Prevention (CDC).

Gao Fu, director of the Chinese Center for Disease Control and Prevention (CDC), said in a conference in Chengdu on the 10th that the protection rate of the vaccine against the new coronavirus in mainland China was low, which sparked a discussion, but Gao denied it afterwards in an interview with the Chinese Communist Party’s Global Times, stressing that it was a complete misunderstanding.

The protection rate of the Kexing vaccine against symptomatic infection of the new coronavirus in mainland China is only 50.4%. It is much lower than the vaccines produced by other countries in the world.

According to the Associated Press, Gao Fu said in a meeting in Chengdu on the 10th that the protection of the vaccine in mainland China is not very high, and since Beijing has not approved any foreign vaccine for use in China, Gao Fu said he is formally considering whether different types of vaccines should be used for vaccination.

However, in an interview with the Global Times on the 11th, Gough categorically denied the claims, saying “this is a total misunderstanding. He responded that in a global discussion among scientists on the efficiency of vaccine protection, he proposed a future scientific thinking that if vaccine efficiency is to be improved, it can be further enhanced by optimizing vaccination procedures and using different technical routes for sequential vaccination.
