Do I need to notify the time of the second dose of COVID-19 vaccine? Can't you go ahead of time?

For inactivated vaccine, the human body may produce antibodies in a short time after the first dose, but the antibody titer is not enough to produce better protection, and the duration is very short. Only by re-inoculation and stimulating the human immune system again, due to the existence of the first dose of immune memory, the immune response will be much stronger than the first time, the antibody level will be greatly improved, and the duration will be greatly prolonged.

It takes time to form the first dose of immune memory. In COVID-19, the inactivated vaccine is generally considered to be 265,438+0 days, so it is necessary to inoculate the second dose at intervals of not less than 265,438+0 days. Premature inoculation should be regarded as invalid inoculation.
