(Fighting against New Coronary Pneumonia) Zhong Nanshan: A new coronavirus vaccine against mutant strains is being developed
China News Service, Guangzhou, April 24 (Cai Minjie) On the 24th, at the 2021 Frontiers of Medical Science Forum of the Chinese Academy of Engineering in Guangzhou, Zhong Nanshan, an academician of the Chinese Academy of Engineering, said through a connection that he is currently working hard to develop a new crown vaccine against mutant strains.
When talking about the precise prevention of the new crown epidemic, Zhong Nanshan said that the main problem currently encountered is the mutation of the new crown virus.
The mutant strains currently appearing come from the UK, Brazil, Nigeria, South Africa and other places.
It now appears that the whole virus inactivated vaccine being used has reduced its effectiveness against the b1351 mutant strain that emerged in South Africa.
In terms of treatment, why are people suffering from new coronary pneumonia, people with similar health conditions are also treated, and some patients quickly deteriorate or even die, but some patients quickly get better?
In response to this phenomenon, Zhong Nanshan believes that “may be closely related to genetic susceptibility.” He is organizing various forces, hoping to find Asians, especially Chinese, who are susceptible to the new crown virus through large-scale population screening. gene.
Zhong Nanshan also said that great attention should be paid to individualization and precise prevention in the development of vaccines.
"The whole world is facing some of the same problems, such as how long the protection lasts after vaccination? Can two or even three shots further increase the protection rate? The first shot is an inactivated vaccine and the next shot. Will the mRNA vaccine be better? How to improve immunity and resist viral infections... These are all unresolved problems and are important issues that need to be solved through the concept of precise prevention and treatment."
Virus mutation is currently one of the main contradictions encountered in global prevention and control.
Zhong Nanshan said: "Now we are working hard to develop vaccines against mutant strains." (End)
