　　On the 27th, the State Council’s Joint Prevention and Control Mechanism held a press conference on furthering the situation regarding epidemic prevention and control and vaccination.

At the meeting, Zheng Zhongwei pointed out that expert analysis believes that the current situation of epidemic prevention and control in my country is very good, and the focus is on foreign defense imports. The import risks are high, such as customs, border inspections, aviation, isolation points, designated medical institutions and other staff. Six months after completing the immunization program, booster vaccination can be carried out.

　　In addition, it was also found in routine vaccination that people with relatively low immune function, and people over 60 years of age, did not have as good an immune effect after vaccination as those aged 18-59, but these people are precisely those at high risk after infection. .

The risk of severe, critical illness, and death after infection is higher than that of other people.

Therefore, experts also suggest that for such people, a booster shot can be given 6 months after vaccination.

　　Experts also suggest that due to the needs of work, study, and communication, some people in my country need to go to high-risk areas or countries outside of the country. It is also recommended that such groups can be boosted after 6 months of vaccination.

　　"But at this stage, whether to carry out booster immunization for the entire population 6 months after vaccination, experts suggest that further research is needed, and a comprehensive study and judgment should be made according to the situation of the epidemic." Zheng Zhongwei said.
