Introduction of reinforcing needle

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 is inoculated with 2 shots in the whole process, and another shot is inoculated according to the degree of decline of human antibody level.

After vaccination in COVID-19 for a period of time, the protective effect is weakened, and strengthening vaccination will make this decline rebound strongly. 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 effect on mutants such as Delta. The protection effect can be improved. According to related research, the antibody level increased more than ten times after the second dose of vaccine was inoculated for half a year. After inoculation, it can maintain a high level for another 6 months.
