|When will China resume normal personnel exchanges? Is the new crown vaccine every year? Zhang Wenhong makes the latest judgment|
On June 3, the second Boao Forum for Asia Global Health Forum was held in Qingdao.
There were 20 sub-forums, 4 salons and many important events.
Focusing on hot topics such as epidemic prevention and control and vaccination of public concern, experts such as Zhang Wenhong, Zheng Zhongwei, Li Lanjuan and others who came to the conference conducted discussions and exchanges and made the latest judgments.
When will the world resume normal personnel exchanges? Will the new crown vaccine be given every year like the flu vaccine in the future? In response to these issues of public concern, at the relevant sub-forums of the Boao Forum for Asia Global Health Forum, Zhang Wenhong, director of the Department of Infectious Diseases of Huashan Hospital affiliated to Fudan University and director of the National Center for Infectious Diseases, gave his latest judgment: "The world has conditions.
The resumption of exchanges 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 next year.
This depends on the speed of vaccination.
In the end, whether we need to vaccinate repeatedly depends on the number of times after the vaccination this year.
At the end of the second year, we will evaluate how many people have been infected or relapsed after being vaccinated.
Recently, there have been new local confirmed cases or asymptomatic infections in many parts of the country.
The epidemic has shown the characteristics of rapid spreading and strong transmission of virus strains.
The situation of epidemic prevention and control is still severe.
Li Lanjuan, academician of the Chinese Academy of Engineering and director of the State Key Laboratory of Infectious Diseases, said in an interview that the current epidemic prevention and control cannot be less vigilant.
Discovering and controlling the source of infection, cutting off the route of transmission, and protecting susceptible populations are the three most important tasks: "People and seafood from the outside must be tested.
If they are found, they will not be spread after isolation.
Sometimes they are not found in time and spread in a local area.
We must continue to strengthen the control of imported epidemics.
Vaccination is the most effective way to protect susceptible people.
According to the latest data from the National Health Commission, as of June 2, my country has vaccinated more than 700 million doses of the new crown vaccine.
Academician Li Lanjuan said that to build an effective herd immunity barrier, we need to continue to promote large-scale vaccination.
She said that she had received two shots of the new crown vaccine and tested antibodies specifically: "Although the vaccine is already being vaccinated on a large scale (in China), it has not yet reached the level of the immune barrier.
70% of people have to be vaccinated to establish immunity.
Barriers will not produce a relatively large-scale epidemic.
Therefore, we will continue to increase the intensity of vaccine injections.
