In this regard, Lei Zhenglong, deputy director of the National Health Commission's Disease Control Bureau and first-level inspector, said, "This reminds us that we cannot relax our prevention of Omi Keron mutant strains."
The National Health Commission will focus on deploying and strengthening the prevention and control of Omi Keron mutant strains in the near future, such as strengthening the prevention of foreign imports at ports, strictly implementing the closed-loop management of the entire process of immigrants, and increasing the sampling inspection rate of high-risk countries inbound; pay close attention to global peace Epidemic trend of Omi Keron mutants in neighboring countries of China, and carry out virus gene sequence determination on all qualified imported cases, imported goods and related environmental positive samples.
In addition, Lei Zhenglong also emphasized that China's existing infection prevention and control measures in medical institutions are still effective against the Omi Keron variant. In the infection prevention and control work in medical institutions, it is still necessary to adhere to the implementation of existing prevention and control measures.
Strict port city prevention and control
Since mid-October this year, many local clusters of epidemics in China have been imported through port cities, including Ejina Banner and Erlianhot in Inner Mongolia, Heihe in Heilongjiang, and Dehong in Yunnan through land ports.

The key is to implement various prevention and control measures, strengthen the control of the source of the epidemic and the safe and orderly flow of personnel.
Recently, the "Notice on Strengthening the Prevention and Control of the New Coronary Pneumonia Epidemic in Port Cities" issued by the Joint Prevention and Control Mechanism of the State Council has made provisions on the prevention and control of the epidemic in land port cities, the control measures for the movement of people, and the nucleic acid testing of staff in high-risk positions and related personnel. Clear requirements, and require land border port cities to do a good job of tourist flow restrictions and risk warnings.
In this regard, Lei Zhenglong said that the strict control requirements for the movement of people in port cities in the "Notice" are mainly based on the consideration of strengthening source control, risk investigation, and reducing aggregation.

Pay attention to "one old and one young" vaccination
Whether the "older and younger" group has any adverse reactions after being vaccinated with the new crown vaccine has attracted social attention.
The vaccines currently used urgently among children aged 3 to 11 years old in China include the vaccine from the Beijing Institute of Sinopharm Group, China Biotech Wuhan Institute, and the inactivated vaccine from Beijing Kexing Zhongwei.
Wang Huaqing, chief expert of the Chinese Center for Disease Control and Prevention's immunization program, said that from the results of previous clinical trials, children vaccinated with these three vaccines have a high conversion rate of neutralizing antibodies. The antibody level is equivalent to that of adults, and some are even higher. aldult.
Talking about the adverse reactions of children after vaccination, Wang Huaqing pointed out that the number of vaccination doses for children aged 3 to 11 years in China has exceeded 140 million doses. From the monitoring results, the adverse reactions are generally stable, and there is no abnormal situation. Adverse reactions are the same as those of other people, mainly fever and local reactions, most of which are general reactions.
Regarding whether there are additional risks for the elderly with booster vaccination, Wang Huaqing said that from the results of adverse reaction monitoring, the occurrence of adverse reactions after booster vaccination has not exceeded the past; from the perspective of the types of adverse reactions, it is mainly general reactions.
"From the current results, serious adverse reactions are very rare in intensified injections." (End)
