How to choose the third booster vaccine?

At present, the third booster vaccine has been carried out in many places. At present, priority is given to key groups and it is open to the eligible public. So, how to choose the third booster vaccine? Is the booster injection free? The following small series will bring an introduction.

How to choose the third booster vaccine?

At this stage, priority is given to the use of vaccines originally vaccinated by production enterprises to strengthen immunization.

In principle, people who use the same inactivated vaccine to complete two doses of vaccination should use the original inactivated vaccine for 1 dose to strengthen immunization;

In principle, people who use different inactivated vaccines to complete two doses of vaccination will be given priority to use the same vaccine as the second inactivated vaccine for 1 dose. In the case that the second dose of the same vaccine can no longer be provided, 1 dose of the same vaccine as the first dose of inactivated vaccine can be used for booster immunization.

People vaccinated with adenovirus vector vaccine still use the original vaccine for booster immunization.

According to reports, the fortified vaccine supplied to Jiaozuo comes from two manufacturers: the inactivated vaccine of Sinopharm Zhongsheng Beijing Company and Beijing Kexing Company.

Is vaccination free?

COVID-19 continues to implement the policy of free vaccination for residents in intensive vaccination, and the vaccine and vaccination costs are borne by the relevant state funds.

Boosting needle, also known as booster immunization, refers to supplementary vaccination according to the fading of antibodies after vaccination to maintain human immunity to the virus. For example, at this stage, COVID-19 inactivated vaccine was inoculated with 2 shots. According to the degree of decline of human antibody level, another shot is needed.

After vaccination in COVID-19 for a period of time, the protective effect is weakened, and strengthening vaccination will make this decline "strongly rebound". According to the research results of Zhongsheng and Beijing Kexing, the antibody level of the recipients will be greatly improved after vaccination. After 14 days of intensive immunization, the antibody level was equivalent to the original 10-30 times. It can be maintained at a high level after 6 months, and has a good cross-neutralization protection effect on mutants such as Delta.

Should all people who have reached the deadline and have no taboos be vaccinated?

Judging from the currently published enhanced vaccination program, there are two kinds of population regulations for open enhanced vaccination, one is fully open to eligible public, and the other is priority population.

At present, priority is given to strengthening the immunization of high-risk groups and people in key positions to ensure the basic operation of society. Gradually expand the scope, and carry out intensive immunization for people 18 years old and above who have been vaccinated with inactivated vaccine and adenovirus vector vaccine for six months. People aged 60 and above are high-risk groups with high risk of serious illness after infection. Qualified suggestions should be given a booster shot as soon as possible.
