On February 19, the joint prevention and control mechanism of the State Council held a press conference on epidemic prevention and control and vaccination. Wu Liangyou, deputy director of the disease control bureau of the National Health Commission, said at the press conference that the current epidemic prevention and control task of "external defense input and internal defense rebound" in China is still arduous. According to the development and application progress of covid-19 virus vaccine, we further supplemented and improved the covid-19 virus vaccine immunization strategy. Recently, with the approval of the joint prevention and control mechanism of the State Council, the National Health Commission has begun to deploy sequential immunization.
Previously, target people over 18 years old who have been vaccinated with inactivated vaccines of Sinopharm Zhongsheng Beijing company, Wuhan company and Beijing Kexing company, as well as adenovirus vector vaccine of Tianjin Cansino Biologics Inc(688185) company for 6 months can receive one dose of secondary homologous booster immunization, that is, the original vaccine can be used for booster immunization. After the implementation of the sequential booster immunization strategy, the target population who has completed the whole process of vaccination with the above three inactivated vaccines can also choose the recombinant protein vaccine of zhifeilongke horse or Cansino Biologics Inc(688185) adenovirus vector vaccine for sequential booster immunization. For the target population, select one of homologous booster immunization and sequential booster immunization. In addition, the joint prevention and control mechanism of the State Council also approved the homologous enhanced immunization of covid-19 virus inactivated vaccine of Shenzhen Kangtai company and the Institute of biology of the medical college. Both homologous enhancement and sequential enhancement are implemented in people over the age of 18 who have completed the whole process of vaccination for 6 months.
He also said that the research data showed that both homologous booster immunization and sequential booster immunization could further improve the immune effect. He hoped that people who met the vaccination conditions could take the initiative to vaccinate and vaccinate as soon as possible, so as to add weight to their health and refuel for epidemic prevention.
