Health And Wellness Commission: The new crown variant strain does not affect the protection of China's new crown vaccine

In response to the question of whether the new coronavirus mutant strain will affect the effectiveness of the current vaccination in China, Zeng Yixin, deputy director of the National Health and Health Commission and head of the vaccine research and development team of the
Joint Prevention and Control Mechanism, said on the 9th that through experiments, our vaccine has the same ability to make a change. For now, at least, it's clear that the mutation won't affect the vaccine's protection.
9, the
joint prevention and control mechanism held a press conference on the recent outbreak prevention and control and vaccination-related situation. At the meeting, a reporter asked: Recently, several places in China have found that the new coronavirus infection from abroad detected a new coronavirus British mutation, this mutation will not affect the effectiveness of the current vaccination?
Zeng Yixin pointed out that the new coronavirus mutation problem has been a hot issue of high concern, so we have set up a special task force from the beginning to study and monitor the new coronavirus mutation. Recently, we have seen, the media also reported that in the United Kingdom, the virus has a new mutation, is the S protein 501 amino acid mutation, because this mutation is just in the key position, is the RBD region of the S protein, this area is the virus and human cells binding to the key part, so this mutation is highly concerned.
said there have also been recent reports that the virus has been found in people returning from abroad. Whether the virus will affect the protection of the vaccine, this situation is of particular concern to the National Health Commission. Recently, two scientific research units have done special research, one is the China Medical
Institute of Experimental Animals, and the other is the Institute of Viruses of Zhongshan University, both units have specifically studied this strain. They compared the viruses that appeared in China in January, February, March, April, May and June with the uk's mutant strains and found that antibodies produced by the new coronavirus immune monkeys and immune bodies, as well as early viral strains in the country and mutant strains in the UK, could be equally positive, and they have submitted to the journal and are awaiting publication.
" results should strengthen our confidence that our vaccine has the same ability to make a strain of resistance to such a mutation. For now, at least, it's clear that the mutation won't affect the vaccine's protection. Zeng Yixin said.
Also pointed out that the mutation of the virus is an ongoing process, which occurs every day. At present, the new coronavirus mutation rate is still in an acceptable range, the rate of variation is not particularly fast. "But we have to pay a lot of attention to this issue, on the one hand, we still have to continue to closely monitor the virus mutation, but also we have to do a good job of coping, in case the mutation accumulates to a certain extent, affecting the protection of our vaccine, we also need to prepare in advance, to carry out broad-spectrum new crown vaccine or mutated new crown vaccine research, in order to effectively respond to possible problems."
