(Fighting New Coronary Pneumonia) China's National Health Commission talks about Delta variants: Existing vaccines still have good preventive and protective effects
China News Agency, Beijing, August 5 (Reporter Ying Ni) He Qinghua, the first-level inspector of the CDC of the National Health Commission of China, said in Beijing on the 5th about the delta variant that the existing vaccines still have good prevention and protection. It can reduce the risk of virus transmission in the population, reduce the transmission power of infected persons, and effectively reduce the incidence of severe illness and mortality after infection.
On the same day, the Joint Prevention and Control Mechanism of the State Council of China held a press conference on further strengthening the epidemic prevention and control situation.
It is understood that as of August 4, a total of 1,726.223 million doses of new coronavirus vaccines have been reported nationwide.
Regarding the Delta mutant strain that is of general concern to the outside world, He Qinghua said that the World Health Organization announced on May 10 this year that the Delta mutant strain will be included in the global new coronavirus mutant strain that needs to be concerned. It is currently circulating in more than 130 countries and regions. It has become the main virus strain of the global new crown pandemic, which has the characteristics of fast transmission, fast replication in the body, and long time to turn negative.
He Qinghua emphasized that relevant scientific research and epidemic prevention and control practices at home and abroad have shown that the Delta mutant strain has not caused a subversive change in the biological characteristics of the new crown virus. The source of infection and the route of transmission are basically clear. The mutant strain is still effective.
Existing vaccines still have good preventive and protective effects, can reduce the risk of virus transmission in the population, reduce the transmission power of infected persons, and effectively reduce the incidence of severe illness and mortality after infection.
He pointed out that some time ago, for the first time, China successfully blocked the local epidemic of delta variants that occurred in several cities in Guangdong Province, which is densely populated and highly mobile, and proved that vaccinations, wearing masks, washing hands frequently, and maintaining social distancing Measures such as avoiding crowd gathering are effective.
