Aiming at the mutation of the new coronavirus, Gao Fu and Zhang Wenhong’s latest research and judgment!

Recently, some epidemiological experts have commented that the mutation of the new coronavirus is basically saturated. Is the new crown virus really “invariable”? Zhang Wenhong, director of the Department of Infectious Diseases, Huashan Hospital Affiliated to Fudan University, emphasized the pressure of the body’s immunity on virus mutations. He said that the virus has always had an “impulse” to mutate, but the immunity produced by human active immunity or infection and repeated infection will restrict the direction of mutation of the new coronavirus. Gao Fu, an academician of the Chinese Academy of Sciences, viewed the mutation of the virus from a broad range of nature. He said that the host range of the new coronavirus is very wide, from tigers and lions to mice and rabbits, and it is still expanding. The possibility of the new coronavirus cannot be ignored. greater challenges. | Related reading (Science and Technology Daily)

Predicting the evolution of the virus may not be what these experts are best at, so let’s take it as a family opinion.

Cao Yunlong, a professor at Peking University, was selected as one of the top ten figures of the year by Nature for predicting the mutation trend of the new coronavirus. The core conclusion of his article is that the convergent evolution trend of the new coronavirus means that the mutation of the new coronavirus can be predicted. But he is not as optimistic as the two experts in the article.

Cao Yunlong believes that after the BA.5.2 and BF.7 infection peaks have passed, it is not ruled out that there will be infection peaks driven by BQ.1.1, XBB or other strains with stronger immune escape capabilities. Cao also believes that making the development cycle of vaccines and antibody drugs keep up with the speed of virus evolution is a follow-up problem that needs to be solved.

Therefore, the virus may not stay at the pathogenicity of Omicron, and there is still great uncertainty in its future direction. Therefore, no matter whether it is a vaccine, a specific drug, or even a prevention and control method, it needs to be constantly improved. evolution.
