| Academician Zhang Boli: The epidemic may rebound this winter, strengthening vaccination is the key |
"This winter, the new crown pneumonia epidemic may rebound
.
" On September 25, at the 2021 Zhongguancun Forum "Second Global Science and Life and Health" parallel forum, the audience immediately took a deep breath as soon as an expert's words were spoken
In this judgment, a reporter from Science and Technology Daily specifically asked Zhang Boli, an academician of the Chinese Academy of Engineering, to verify
.
Zhang Boli said that from the current situation, Delta virus is a dominant strain, and it is indeed very contagious.
academician
"Therefore, the experts are right to make the above judgment.
We still have to guard against this in autumn and winter.
The spread of epidemics and local outbreaks cannot be completely avoided.
We need to be more vigilant
.
" Zhang Boli said
How to prevent it? Zhang Boli clearly pointed out that it is necessary to strengthen the vaccination.
Although the vaccine's protective effect on virus infection has declined, it is still very effective in preventing the severe disease rate and mortality rate, and the effective rate can reach 80%-90%
.
Indeed, experts at the meeting also believe that, although the overall trend of the global new crown epidemic has improved, there may still be local outbreaks.
The domestic epidemic situation is generally stable, but there are still risks of epidemic import and local epidemics
.
At the same time, the continuous accumulation of mutations of the new crown virus has led to an increasing transmission power, and the new crown pneumonia may have a "flu-like" trend in the future
"Vaccines provide basic immunity and can reduce the burden of disease
.
That is to say, it may prevent infection a little bit, prevent disease, and prevent transmission, but it can't prevent all, but it has obvious effects in preventing severe illness and preventing death
Academician of the Academy of Sciences
As for the intensive injection that the public is concerned about? Yin Zundong, director of the China Centers for Disease Control and Prevention's Immunization Planning Center, said that WHO believes that the evidence for boosting immunization is insufficient at this stage.
The need and timing of boosting immunization will be based on the evidence of the same technology platform, different technology platform vaccines, and new variant strain vaccines.
To evaluate and determine
.
The United States believes that booster immunization is necessary, but the need for booster immunization varies among different groups of people
"Our country's consideration of enhanced immunization with the new crown vaccine is to focus on key populations, such as customs, border inspections, aviation, isolation points, designated medical institutions and other personnel with high import risks; people with relatively low immune functions and people over 60 years of age.
Due to the needs of work, study, and communication, people in high-risk areas or countries outside of the country can carry out booster vaccination 6 months after completing the immunization program
.
” Yin Zundong said, but further research on booster vaccination for the whole population needs to be carried out according to Comprehensive research and judgment on the epidemic situation
