On February 19, the joint prevention and control mechanism of the State Council held a press conference to introduce the epidemic prevention and control and vaccination work. At the meeting, Wu Liangyou, deputy director of the Disease Control Bureau of the National Health Commission, introduced that recently, with the approval of the joint prevention and control mechanism of the State Council, the National Health Commission has begun to deploy a sequence to strengthen immunization.
Previously, the target population over the age of 18 who had been vaccinated with Sinopharm Zhongsheng Beijing Company, Beijing Kexing Company, Sinopharm Zhongsheng Wuhan Company inactivated vaccine or Tianjin CanSino Company's adenovirus vector vaccine for 6 months could be subjected to a dose of homologous enhanced immunization, that is, strengthened with the original vaccine.
After the implementation of the sequential enhanced immunization strategy, the target population who has completed the full vaccination of the above three inactivated vaccines can also choose the recombinant protein vaccine of Zhifeilong Koma or the adenovirus vector vaccine of Cansino for sequential enhanced immunization. For the target population, homologous booster immunization and sequential booster immunization can be selected.
In addition, the joint prevention and control mechanism of the State Council also approved the homologous enhanced immunization of the new coronavirus inactivated vaccine of Shenzhen Kangtai Company and the Institute of Biology of the Medical Academy. Whether it is homologous enhancement or sequential strengthening, it needs to be implemented in people over 18 years of age who have completed the full vaccination for 6 months.
The research data shows that homologous enhanced immunization and sequential enhanced immunization can further improve the immunization effect, and people who hope to meet the vaccination conditions can take the initiative to vaccinate and vaccinate early, increase health and fuel epidemic prevention.
Hot spots to dispel doubts
At the meeting, Wang Huaqing, chief expert of the immunization program of the Chinese Center for Disease Control and Prevention, introduced that there are some special precautions for sequential vaccination.
1. The target is a person over 18 years old;
2. Completed 2 doses of inactivated covid-19 vaccination against Sinopharm Zhongsheng Beijing Company, Beijing Kexing Company and Sinopharm Zhongsheng Wuhan Company;
3. No booster immunization has been carried out.
Populations that meet the above requirements can receive sequential booster immunization.
