Director of the Chinese Center for Disease Control and Prevention Gao Fu: China will consider opening its borders if the vaccination rate exceeds 85% by early 2022. He believes that if the vaccination rate reaches more than 85%, there will be very few infections, and the infected people will not be seriously ill or die.
Gao Fu, director of the Chinese Center for Disease Control and Prevention, recently said in an interview with CCTV News' "Relativity" reporter Zhuang Shengchun that he hopes that by the beginning of 2022 or even the end of this year, China can reach a new crown vaccine vaccination rate of 70%-80%, basically achieving Herd immunity . “How much vaccine is effective depends on the characteristics of the virus itself. We now estimate that the basic transmission index of the new coronavirus is 70% to 80%,” Gao Fu said. “Vaccine vaccination is a very complex and comprehensive process. Everyone is Work hard. I hope that saying 'early next year' is wrong. I hope we can achieve it by the end of this year. This sentence itself also hopes to promote and accelerate this. "
He also said that if China's vaccination rate exceeds 85% in early 2022, countries will consider opening borders. When the vaccination rate reaches this level, the number of infections will be very few, and even if they are infected, there will be few serious cases or deaths. "When that time comes, why can't we open it up?"
Recently, the recombinant new coronavirus vaccine (CHO cells) jointly developed by the Institute of Microbiology, Chinese Academy of Sciences and partner companies has been approved for emergency use in China. This is also the first in the world. The new coronavirus recombinant subunit protein vaccine approved for clinical use. As one of the researchers of the vaccine, Gao Fu told CCTV News "Relativity" that the vaccine has a simple composition and may avoid possible side effects caused by other ingredients. The results of the vaccine phase I and II clinical trials are very good, and the phase III clinical trial of the vaccine has good results. Very good results have also been seen, but the clinical trials are not yet over. Gao Fu also responded in the interview as to why three shots of this vaccine are needed.
Gao Fu also emphasized that this is the first time that humans have been vaccinated against the new coronavirus . There is no scientific evidence to say which vaccine is the best. Countries will determine which vaccine to develop first based on actual conditions, but in the end they may all reach the same goal. He emphasized that the vaccine is the ultimate product for mankind to eliminate the new coronavirus. called on everyone to have confidence in the vaccine.
At the second conference of the Boao Forum for Asia Global Health Forum, Zhang Wenhong, director of the Infectious Diseases Department of Huashan Hospital affiliated to Fudan University and director of the National Medical Center for Infectious Diseases, some countries will begin to resume international exchanges in the second half of 2021.
He said: "Countries around the world will conditionally resume personnel exchanges, which will begin in the second half of this year. We hope that China can conditionally resume exchanges with some countries in the first half of 2022, depending on the speed of vaccination. Ultimately Whether we need to be vaccinated repeatedly depends on whether we will do it again at the end of the second year after the vaccine is administered this year. Evaluate how many people are still infected or have relapsed after being vaccinated.
Get vaccinated as soon as possible to meet the needs of conditional opening. China can conditionally resume people-to-people exchanges with countries in the world that have good vaccination and low incidence rates.”
Zhang Wenhong said that some countries with relatively high vaccination rates, such as Israel, the United States, and the United Kingdom, will "secretly" resume personnel exchanges in the second half of this year.
But this is not because other countries do not accept them, but because vaccination in other countries has not been completely completed.
As for when global travel can be fully restored, Zhang Hongwen said he was unable to determine.
