How long is the interval between two injections of COVID-19 vaccine and three injections of COVID-19 vaccine

Interval between two doses of COVID-19 vaccine

COVID-19 inactivated vaccine (Vero cells) needs to be inoculated with two doses: the interval between two doses is recommended to be ≥ 3 weeks, and the second dose should be completed as soon as possible within 8 weeks. That is to say, the second dose of vaccination should be completed within 21 to 56 days after the first dose.

Interval of 3 doses of COVID-19 vaccine

Three doses of recombinant COVID-19 vaccine (CHO cells) need to be administered: the interval between two adjacent doses is recommended to be ≥ 4 weeks. The second dose should be completed within 8 weeks after the first dose, and the third dose should be completed within 6 months after the first dose.
