Don't panic yet!
The first edition of COVID-19 vaccination technical guidelines issued by the National Health Commission clearly pointed out that:
Inoculate two doses of inactivated COVID-19 vaccine, the interval between two doses is suggested to be ≥3 weeks, and the second dose should be completed as soon as possible within 8 weeks. Three doses of recombinant COVID-19 vaccine should be inoculated, and the interval between two adjacent doses should be ≥4 weeks. The second dose should be completed within 8 weeks after 1 dose, and the third dose should be completed within 6 months after 1 dose.
That is to say, between the first dose and the second dose of COVID-19 vaccine, the national proposal is: 2 1 day ≤ interval ≤56 days.
According to the current evidence-based evidence analysis, delaying vaccination will generally not affect the prevention effect. The "Guide" clarifies that if 2 or 3 doses of vaccination are not completed according to the procedure, it is recommended to replant as soon as possible. There is no need to restart the immunization program, just replant and complete the corresponding dose.
In view of the problem that some people have recently reported that it is difficult to make an appointment for the second shot, Mi Feng, deputy director of the Propaganda Department of National Health Commission, also made it clear that at present, the state has fully considered the scheduled demand for the second shot when allocating and supplying vaccines for various provinces. All localities should make accurate arrangements to ensure that the second vaccination is completed within 8 weeks to avoid the situation that the needle is not finished. The permanent working group of the National Health Commission will also strengthen its supervision.
What would happen if I didn't get the second shot?
A: The determination of vaccine immunization program is based on the results of research and development stage and clinical trial stage, in order to obtain the best safety, immune response effect and immune persistence. It is difficult to obtain the best immune response effect and immune persistence without completing the whole vaccination.
