Zhong Nanshan: domestic vaccines are effective against delta mutant
Academician Zhong Nanshan's latest research and judgment: domestic common vaccines are effective for "delta" mutant, minors and the elderly should speed up vaccination
CCTV news: the "delta" mutant virus, which caused local outbreaks in many places in Guangdong, is now spreading around the world. Faced with the characteristics of "delta" mutant virus, such as strong transmission power, short incubation period, and immune escape phenomenon, people are concerned about the degree of protection of existing vaccines? Yesterday (June 25), academician Zhong Nanshan, academician of the Chinese Academy of engineering and director of the National Clinical Research Center for respiratory diseases, made the latest judgment. Zhong Nanshan said that the commonly used domestic vaccines are effective against the delta variant, and China needs to continue to maintain the "acceleration" of vaccination.
Zhong Nanshan said that in response to the epidemic situation, Guangzhou has achieved phased results in the first phase of the campaign to deal with the community infection of "delta" mutant virus by rapidly targeting the source of infection, accurately identifying the transmission chain, and updating the concept of "tight connection".
Zhong Nanshan pointed out that at present, the commonly used domestic vaccines are effective against the "delta" mutant strain, and we should speed up the pace of "taking as much as possible".
Zhong Nanshan said that in the spread of the "delta" mutant virus, the main and severe patients were the elderly, and they also had children. Therefore, these two groups of people should strengthen vaccination.
For the possible recurrence of "delta" mutant virus infection, the fever clinic of the hospital should strengthen the control measures, at the same time, the isolation place should be more standardized, and 5000 independent international health stations will be built in Guangzhou.
What does it mean for antibody to weaken after a period of vaccination? Zhong Nanshan said that the decline of antibody titer does not completely mean the disappearance of its protective function.
