CCTV News:The "Delta" mutant strain, which caused local epidemics in many places in Guangdong, is now spreading around the world. Faced with the characteristics of "Delta" mutant strain, such as strong transmission, short incubation period, and possible immune escape, how much people are concerned about the protection of existing vaccines? Yesterday (June 25th), Academician Zhong Nanshan, academician of China Academy of Engineering and director of the National Center for Clinical Medicine of Respiratory Diseases, made the latest judgment. Zhong Nanshan said that the commonly used vaccines made in China are effective for the "Delta" mutant, and China needs to continue to maintain the "acceleration" of vaccination.
Zhong Nanshan said that Guangzhou has made initial achievements in the first phase of the campaign to deal with the community infection of Delta virus through scientific measures such as quickly locking the source of infection, accurately identifying the transmission chain and updating the concept of "close contact".
Zhong Nanshan pointed out that at present, the commonly used vaccines made in China are effective against the "Delta" mutant strain, and everyone should speed up the pace of "all-in-one".
Zhong Nanshan said that in the spread of the "Delta" mutant strain, the main and severe patients were mostly elderly people, but also children. Therefore, these two groups of people should strengthen vaccination.
For the possible reappearance of "Delta" mutant virus infection, the hospital’s fever clinic should strengthen control measures, and at the same time, the isolation place should be more standardized. Guangzhou will build 5,000 independent international health stations.
What does it mean to weaken antibodies after vaccination for a period of time? Zhong Nanshan said that the decrease of antibody titer does not completely mean that its protective function disappears.
