On December 20, the joint prevention and control mechanism of the State Council held a press conference, which was attended by heads of the Ministry of transport, the National Health Commission and other departments, as well as the chief expert of immunization planning of China CDC to introduce the situation of scientific and accurate epidemic prevention and control, and answer media questions. At the meeting, Lei Zhenglong, deputy director of the disease control bureau of the National Health Commission, introduced that the current epidemic situation in the country is generally stable. The Xi'an Dongguan related epidemic is still developing, and the risk of continuous transmission between the two places is high. Recently, sporadic spillover cases were found, and the investigation of risk personnel is being stepped up. The input pressure of China's foreign defense continues to increase Mi Feng, spokesman of the National Health Commission, introduced at yesterday's press conference that at present, 89 countries and regions around the world have reported Omicron mutants. The epidemic situation in some neighboring countries in China is growing rapidly, and the pressure of "external defense input" continues to increase. The top priority of epidemic prevention and control is ports. The key is to implement various prevention and control measures, strengthen the control of epidemic source and the safe and orderly flow of personnel. Lei Zhenglong, deputy director of the disease control bureau of the National Health Commission, also said at the press conference that the imported cases of Omicron mutant strains were reported in Tianjin, Guangzhou and Changsha, and the local cases caused by the imported cases of Omicron mutant strains were reported in some regions, suggesting that the prevention of Omicron mutant strains should not be relaxed at all. According to his introduction, in the near future, the National Health Commission will focus on the following aspects to strengthen the prevention and control of Omicron mutant strains: first, adhere to the "simultaneous prevention of people" and strengthen the import of external prevention at ports; Second, strengthen the management of centralized isolation places and strictly prevent cross infection; Third, strengthen monitoring and early warning; Fourth, strengthen emergency response to epidemic situations. Liu Haitao, director of the border inspection and Management Department of the State Administration of immigration, also said on the same day that the immigration administration will unswervingly and faithfully implement the measures of "external defense input and internal defense rebound", continue to adhere to the strict exit and entry policy, implement the non necessary and non urgent non exit, and ensure that the people have a good "two festivals". Spillover cases found in Xi'an Dongguan related epidemic Lei Zhenglong pointed out at yesterday's press conference that the current national epidemic situation is generally stable. Lei Zhenglong also introduced that the related epidemic situation in Manzhouli, Inner Mongolia has been basically controlled. The epidemic situation in Shaoxing, Zhejiang Province has slowed down and the risk of epidemic spillover has been reduced. The epidemic situation in Ningbo, Hangzhou, Shanghai, Jiangsu and Anhui has been basically controlled. At the same time, the Xi'an Dongguan related epidemic continues to develop, and the risk of continuous transmission between the two places is high. Sporadic spillover cases have been found recently, and the investigation of risk personnel is being carried out quickly. In addition, for the local cases reported in Guangzhou caused by the imported cases of overseas Omicron mutant, risk personnel screening measures have been taken in time, and the risk of continuous transmission is low. The cases reported in Xiamen and Chengdu that were found among closed-loop managers had a low risk of community transmission. Lei Zhenglong revealed that at present, there are still working groups of the joint prevention and control mechanism of the State Council to guide the disposal of the epidemic situation in Inner Mongolia, Shaanxi, Zhejiang and other regions. The National Health Commission will pay close attention to the epidemic situation in various regions, and work with relevant departments to guide all regions to implement various prevention and control measures in place to control the spread of the epidemic. More than 140 million children aged 3 to 11 received the new crown vaccine In terms of vaccination, MI Feng introduced 20 days ago. As of December 19th, the national total reported 2 billion 684 million 290 thousand doses of COVID-19 vaccine, and the number of people who completed the whole process was 1 billion 193 million 466 thousand. Wang Huaqing, chief expert of immunization planning of China CDC, introduced at the meeting that at present, the number of new crown vaccines for children aged 3 to 11 in China has exceeded 140 million. From the monitoring results, the adverse reactions were generally stable without abnormalities. Wang Huaqing said that at present, the vaccines urgently used among children aged 3 to 11 include the vaccine of Beijing Institute of biology of China, the vaccine of Wuhan Institute, and the new crown inactivated vaccine of Beijing Kexing Zhongwei. According to the results of preliminary clinical trials, children with these three vaccines have a high positive conversion rate of neutralizing antibodies, and the antibody level is equivalent to that of adults, and some are higher than that of adults. In addition, like other people, the adverse reactions are mainly fever and local reactions, most of which belong to general reactions. In the light of which children can not be vaccinated with new crown vaccine, Wang Huaqing pointed out that in the early COVID-19 vaccination technology guide, there are already clear rules and regulations, which are also operated and executed according to this regulation. There are five main cases: allergy to new crown vaccine or allergy to the ingredients of COVID-19 vaccine. The vaccine of the same technical route has been inoculated before, resulting in acute allergy; In the past, no matter what kind of vaccine, as long as there was a serious allergic reaction; Suffering from serious nervous system diseases not fully controlled, including transverse myelitis and demyelinating diseases; Children are in fever or suffering from acute disease or acute attack of chronic disease, or serious chronic disease has not been effectively controlled. Wang Huaqing said that there are some other specific provisions. Whether it is the seed recipient or the vaccinated doctor, they should implement them in accordance with other specific provisions of the manual, grasp the contraindications and the safety of vaccination.
