Recently, Academician Zhong Nanshan made a judgment on when the new crown vaccine will be put into use in a live broadcast.
Zhong Nanshan said that after natural immunization requires 60-70% of people in a country to be infected, it will probably cause 30-40 million deaths, which is too expensive. Therefore, the solution to the epidemic still depends on large-scale vaccination. The new crown vaccine can be used as an emergency as early as autumn or the end of this year.
According to Zhong Nanshan, six vaccines have been tested in clinical trials in Chinese mainland.
A few days ago, Zhong Nanshan also said that China's vaccine research progress is in the first echelon in the world, and we will not lag behind other countries. Generally speaking, vaccines are the main method to solve group immunity.
As for the new coronavirus vaccine, Zhang Wenhong said in late May that the first successful vaccine is expected to be seen in March next year.
Zhang Wenhong believes that from the third phase of clinical results to the world, there will be enough output for most people to use. I believe this time node will not be completed by the end of next year.
In late May, academician Gao Fu, member of the National Committee of the Chinese People's Political Consultative Conference and director of the Chinese Center for Disease Control and Prevention, gave the judgment that a good vaccine requires one and a half years or two years of long-term research and development because it needs to meet the three conditions of "safety, effectiveness and controllable quality". Facing the emergency situation of new coronavirus, a new infectious disease, it is expected to use vaccines for some special groups before the end of the year.
