On June 6, Academician Zhong Nanshan and Academician Li Lanjuan visited Baidu Health Medical Code. Academician Zhong Nanshan mentioned in the live broadcast that the new crown vaccine can be used as an emergency as early as this fall or the end of the year. Six vaccines in mainland China are already in clinical trials.
On June 6, two academicians, Zhong Nanshan and Li Lanjuan, visited the Baidu Health Medical Code. They made live broadcasts on topics such as the infectiousness of asymptomatic patients, the cure rate of new coronary pneumonia, group immunization, and subsequent follow-up prevention.
During the live broadcast, academician Zhong Nanshan talked about when the new crown patients were the most infectious. He pointed out that droplets and contact were the definite source of infection. The infection was the most contagious 5 days before and 5 days after the onset of symptoms. Significantly decreased.
When talking about "group immunization", Academician Zhong Nanshan pointed out that the group immunization proposed by some countries is a natural infection without any intervention, and gradually establishes the process of immunization. "To establish'group immunity', 60%-70% of the population must be infected. According to the mortality rate of the new coronary pneumonia, 6.95% of the world's deaths can gradually establish group immunity, which will probably cause 30-40 million deaths. That's too expensive! Therefore, this kind of "group immunity" is not feasible. If you want to establish "group immunity", you still have to rely on the research and development of vaccines. The new crown vaccine can be used as an emergency as early as this autumn or the end of the year. There are already 6 clinical trials in mainland China. in."
As for whether the asymptomatic infected person is really no sign, whether it is highly contagious, academician Li Lanjuan said that the asymptomatic infected person is less infectious than the early infected person, and many asymptomatic infected persons heal themselves after infection and do not cause strong Immune response.
"Asymptomatic people are also infectious, and they still need to be strictly isolated to prevent their spread to other people. The Chinese are still susceptible and can't relax their vigilance now."
