Yesterday afternoon, the Joint prevention and control mechanism of The State Council held a press conference.At the meeting, Wu Liangyou, deputy director of the DISEASE control and Prevention Bureau of the NHC, said that the omicron variant strain has become the dominant strain imported from overseas and the local epidemic in China, and its transmission capacity is about twice that of the Delta variant strain.Recently, with the approval of the Joint prevention and control mechanism of The State Council, the NHC has started to deploy sequential enhanced immunization.The transmission capacity of the Omicron strain is about twice that of the Delta variant. At present, the Omicron variant strain has become the dominant strain imported from abroad and the local epidemic in China, with stronger transmission power and faster transmission speed, and the risk of imported and local epidemic in China has greatly increased.According to the epidemiological analysis of existing cases, the average interval between infection cases of Omicron is 3 days, which is further shorter than about 4 days of the Delta variant. The transmission capacity of the Omicron variant is about twice that of the Delta variant, and the transmission capacity is stronger.The symptoms of Omicron infection are atypical and the process of transmission is more subtle.The cases were mainly classified as mild and ordinary, with relatively mild symptoms and atypical imaging changes.The National Health Commission (NHC) has started to deploy sequential enhanced immunization, according to a press conference on Wednesday, approved by the Joint prevention and control mechanism of The State Council.Previously, target groups aged 6 months and over 18 who received inactivated vaccines from Sinopac Beijing, Sinopac Beijing, Sinopac Wuhan or adenovirus vector vaccines from Tianjin Concino could receive a single dose of secondary homologous booster immunization, that is, a booster with the original vaccine.After the implementation of the sequential enhanced immunization strategy, the target population that has completed the whole vaccination of the three inactivated vaccines mentioned above can also choose the recombinant protein vaccine of Zhiphirongoma or the adenovirus vector vaccine of Concino for sequential enhanced immunization.For the target population, either homologous booster immunization or sequential booster immunization can be selected.In addition, the Joint prevention and control mechanism of The State Council also approved homologous enhanced immunization of novel Coronavirus inactivated vaccines from Shenzhen Kangtai Company and the Institute of Biology of Chinese Academy of Medical Sciences.Both homologous booster and sequential booster should be implemented in people over 18 years of age who have completed the full course of vaccination for at least 6 months.The first target for sequential immunization is the population over the age of 18.The second is to complete two doses of inactivated vaccine vaccination, and these two doses are the Novel Coronavirus inactivated vaccine of Sinophem Beijing Company, Sinophem Beijing Company and Sinophem Wuhan Company.The third is to complete the entire 2 doses of vaccination, and the interval of vaccination should not be less than 6 months.The fourth is that there is no enhanced immunity, that is, the third injection did not hit, such several conditions, we must strictly grasp.Research data show that both homologous and sequential strengthening of immunization can further improve the immunization effect. It is hoped that people who meet the vaccination conditions can take the initiative to vaccinate and vaccinate early, so as to improve their health and fuel the epidemic prevention.Cognate, sequential, how to understand?How do I do it?What is homologous booster immunization?Homologous booster vaccination refers to the use of vaccines on the same technical route as primary immunization.In the case of the novel coronavirus vaccine, if two doses of the inactivated vaccine have been given before and booster shots are given with the inactivated vaccine, it is called “homologous booster vaccination.”What is sequential booster immunization?Sequential booster immunization refers to the use of vaccines with a different technical route from primary immunization.For example, if two doses of inactivated COVID-19 vaccine have been given before, and subsequent booster shots have been given with any other non-inactivated COVID-19 vaccine, it is considered as “sequential booster vaccination”.At present, there are two combinations of sequential immunization: inactivated vaccine (Vero cell) 2 doses of basic immunization + recombinant protein vaccine (CHO cell) 1 dose of immunization;Inactivated vaccine (Vero cell) 2 doses of basic immunization + 1 dose of adenovirus vector vaccine to enhance immunity.Iii. How safe is sequential immunization?Available data indicate that both sequential booster immunization regimens can significantly increase the level of neutralizing antibodies in recipients with good safety.Iv. Can sequential booster immunization be carried out for people over 60 years old?Older persons over 60 years of age are at high risk of novel Coronavirus infection.People over 60 years old who meet the requirements for sequential booster immunization can choose sequential booster immunization.5. Is COVID-19 vaccination free of charge under the sequential enhanced immunization program?At present, the sequential strengthening of immunization is free of charge.People who meet the requirements of sequential booster immunization can choose recombinant protein vaccine or adenovirus vector vaccine and receive 1 dose of booster vaccination free of charge.Vi. What should be paid attention to when receiving booster shots of COVID-19 vaccine?Before vaccination, according to the previous vaccination certificate, confirm whether they are 18 years old or above and whether they have completed basic immunization for more than 6 months.During vaccination, students should bring their identification documents and vaccination certificates, and take good personal protection according to the requirements of epidemic prevention and control, and cooperate with on-site vaccination staff to inquire and register.After inoculation, observe the site for 30 minutes, keep the skin clean and avoid scratching the inoculation site.Seven, have been vaccinated “strengthening needle”, can sequential strengthening immunization?The target population can freely choose to carry out homologous booster immunization with the original technical route vaccine, or choose to carry out sequential booster immunization with different technical route vaccine, but cannot receive sequential booster immunization and homologous booster immunization at the same time.Repeat vaccination is not required for people who have completed the “booster” vaccination with inactivated vaccine.Reprint please specify palm thistle zhou source: Tianjin Broadcasting
