China News Service, May 14th. Shao Yiming, a researcher at the China Centers for Disease Control and a member of the Vaccine Research and Development Team of the Scientific Research Group, said on the 14th that my country’s inactivated vaccines and foreign mRNA vaccines are more effective against South African mutants, British mutants, and Brazil. The mutant strain still has a protective effect.
At present, the existing vaccines are still effective against most mutant strains. As long as the immune barrier is established through vaccination and the spread of the virus is blocked, the occurrence of the mutant strains will be blocked.

On the 14th, the State Council's Joint Prevention and Control Mechanism held a press conference on "foreign defense import" and vaccination.
At the meeting, a reporter asked a question that since the end of last year, new variants of the new coronavirus have continued to appear. Foreign studies have shown that some variants have a certain impact on the effectiveness of the vaccine. Can the vaccines currently inoculated in my country resist these new variant viruses.
Shao Yiming said that domestic vaccine development companies and vaccine research institutions attach great importance to this issue and have carried out a series of studies.
Virus mutant strains are an eternal theme. The virus will always mutate during its spread, and it has been tracked domestically and internationally.
Shao Yiming pointed out that the new coronavirus variant virus can be roughly divided into two categories. One is the early variant strain that was circulating in the first half of last year. Research results show that these variant strains will not affect the protective effect of my country's vaccines.
The second category is a few on the WHO list of concerns, such as the British variants, South African variants, Brazil variants, etc. For these strains, clinical trial data, cross-neutralizing antibody protection data, and more Important real-world studies on a scale of one million people show that my country’s inactivated vaccines and foreign mRNA vaccines still have protective effects on South African mutants, British mutants, and Brazilian mutants.
"Under this situation, I want to emphasize that virus variants will continue to appear, but there must be a condition that the virus must continue to spread." Shao Yiming said, "Currently, the existing vaccines are still effective against most of the mutant strains. Therefore, we must vaccinate as soon as possible. As long as the immune barrier is established through vaccination to block the spread of the virus, the occurrence of mutant strains will be blocked. Here, we also call on the capable countries in the world to be like China To vaccinate as soon as possible."
"At the same time of domestic vaccination, my country has made a lot of contributions to the world's vaccination. For example, we have donated vaccines to more than 80 countries and exported vaccines to more than 50 countries. Only the global immune barrier can block the mutant virus. The occurrence and spread of the new crown epidemic in various countries can finally end the new crown epidemic." Shao Yiming said.
