Shao Yiming, a researcher at the China Center for Disease Control and prevention, said that at present, after vaccination, the antibody level of all vaccines will decline over time. However, immune memory still exists, so once the virus is infected, it can stimulate a strong memory response in a very short time, and the antibody will rise significantly. To strengthen immunization, countries are conducting research. At present, there is not enough evidence to show that the third dose of vaccination is needed for the whole population. Preliminary observation shows that it is not necessary to carry out intensive needle vaccination for the general population who have completed immunization within one year.
