China News Service, January 9th. In response to the question of "Whether the mutant strain of the new coronavirus will affect the effectiveness of the vaccines currently vaccinated in my country", the deputy director of the National Health Commission and the head of the vaccine development team of the Joint Prevention and Control Mechanism Research Team of the State Council Zeng Yixin said on the 9th that experiments have shown that our vaccine has the same neutralizing ability against such a mutant strain.

At least it seems that the mutation of this virus will not affect the protection of the vaccine. This is very clear.

　　On the 9th, the State Council’s Joint Prevention and Control Mechanism held a press conference on the recent situation of epidemic prevention and control and vaccination.

At the meeting, a reporter asked: Recently, several places in China have found that a British mutant of the new coronavirus has been detected in people who have returned from abroad. Will this mutation affect the effectiveness of the current vaccine?

　　Zeng Yixin pointed out that the mutation of the new coronavirus has always been a hot issue of great concern to everyone, so we have set up a special task force from the beginning to study and monitor the mutation of the new coronavirus.

Recently everyone has seen it and the media has also reported that in the UK, a new mutation has occurred in the virus, which is the mutation of the 501st amino acid of the S protein, because this mutation is just at the key position, which is the RBD region of the S protein, which is the virus. The key part of binding to human cell receptors, so this mutation is highly concerned.

　　Zeng Yixin said that there have also been reports recently that the virus has been found in people returning from abroad.

Will this virus affect the protection of the vaccine? The National Health Commission pays special attention to this situation.

Recently, two scientific research units have done special research, one is the Institute of Medical Laboratory Animals of the Chinese Academy of Medical Sciences, and the other is the Institute of Virology at Sun Yat-Sen University. Both of these units have conducted special research on this strain.

They compared the viruses that appeared in my country in January, February, March, April, May, and June with the mutant strains in the UK. The virus strains of the United Kingdom and the mutant virus strains of the United Kingdom can also be neutralized. They have submitted articles to the magazine and are waiting for publication.

　　"This result should strengthen our confidence that our vaccine has the same neutralizing ability against such a mutant strain. At least for now, it seems that the mutation of this virus will not affect the protection of the vaccine. This is very clear." Zeng Yixin Say.

　　Zeng Yixin also pointed out that the mutation of the virus is a continuous process that happens every day. It seems that the mutation speed of the new coronavirus is still within an acceptable range, and the mutation speed is not particularly fast. "But we must pay close attention to this issue. On the one hand, we must continue to closely monitor the virus mutation. In addition, we must also respond to it. If mutations accumulate to a certain degree and affect the protection of our vaccines, we must also do Prepare in advance and carry out research on a broad-spectrum new crown vaccine or a mutated new crown vaccine to effectively deal with possible problems."
