Near the end of the year, the overall situation of the prevention and control of the new crown virus pneumonia epidemic is still grim, the overall mutation of the new crown virus is accelerating, and the number of countries in the world where mutations have been found is increasing. On December 15, the Provincial Center for Disease Control and Prevention issued a reminder: vaccination against the new crown virus is an effective means to prevent the new crown virus infection, reduce the incidence and severe disease rate of new crown pneumonia, and it is recommended that people over the age of 18 who have been immunized for 6 months actively receive the new crown vaccine to strengthen the injection!
According to reports, in accordance with the requirements for the new crown vaccine to strengthen the injection, people over the age of 18 can voluntarily go to the new crown vaccination clinic and continue to receive the new crown vaccine reinforced injection free of charge after the second dose of the new crown inactivated vaccine produced by Beijing Biology (including Lanzhou Biology, Changchun Biology, Chengdu Biology), Beijing Kexing and Wuhan Biology, or after half a year of vaccination with the adenovirus vector new crown vaccine produced by CanSino.
Provincial disease control experts said that strengthening immunization refers to supplementary vaccination according to the situation of antibody regression after completing vaccination, and maintaining the body's immunity to the virus. For example, at this stage, the new crown inactivated vaccine is fully vaccinated with 2 injections, and then one injection is carried out according to the degree of decline in the level of antibodies in the human body. Statistics show that as of 10 December, 6 million people over the age of 18 have met the time interval requirements for enhanced immunization.
Why is COVID-19 vaccine boosted? Experts said that after a period of covid-19 vaccination, there is a weakening of the protective effect, and the strengthening of the vaccination of the needle will cause a "strong rebound" in this decline. According to the research results of Sinopharm Zhongsheng and Beijing Kexing, after vaccination of reinforcing needles, the antibody level of the recipients will be greatly improved. After 14 days of enhanced immunity, the antibody level is equivalent to 10-30 times the original, and after 6 months, it can be maintained at a high level. The results of the study show that there are no serious adverse reactions to boost immunity, and neutralizing antibodies will grow rapidly.
Who can be immunized? The policy stipulates that according to the needs of epidemic prevention and control, people aged 18 and above who have completed the full immunization for 6 months can be injected with reinforcing injections. Strengthen the vaccination of high-risk groups of infection, key positions to ensure the basic operation of society, and high-risk groups at high risk of severe illness after infection aged 60 and over.
According to reports, according to the current national vaccination plan, it is recommended to use the same technical route vaccine for intensive vaccination. For example, 2 doses of inactivated vaccination, also an inactivated vaccine, have been completed, and priority is given to boosting immunization with the same vaccine as the second dose of inactivated vaccine. If, inactivated vaccines with the same dose as the second dose, cannot continue to be available, immunization can be boosted with the same vaccine as the first dose. People vaccinated with adenovirus vectors are still immunized with adenovirus vector vaccines.
The provincial disease control department reminds the public that vaccination is everyone's responsibility, through the orderly vaccination of the new crown vaccine can establish an immune barrier in the population, effectively prevent and control the epidemic of new crown pneumonia epidemic, if you meet the conditions for strengthening immunization, please give a booster injection as soon as possible!
