The second needle didn't call after receiving the text message.

According to the current evidence, delaying vaccination will generally not affect the immune effect. If two injections are not completed within the time interval specified in the vaccination procedure, replanting should be done as soon as possible, and there is no need to start again.

In other words, if you get the first shot of inactivated COVID-19 vaccine, but the second shot is not given on time, then you only need to get the second shot as soon as possible.

It is suggested that the inoculation interval between two injections should be ≥3 weeks (2 1 day), and the second injection should be completed as soon as possible within 8 weeks (56 days). Therefore, 2 1 days after the first injection, please take the second injection as soon as possible, so as to play a better protective effect as soon as possible.

At present, the immunization program of inactivated vaccine recommended by COVID-19 in China is two shots in the whole process. From the perspective of individual protection effect, the immune effect of two inactivated vaccines is better than that of one vaccine.

Only when the whole vaccination is completed can the human body produce better immune effect.

The second needle should be inoculated in the original inoculation unit in principle. Because of work, travel and other special circumstances can not be vaccinated in the original vaccination unit, can also be vaccinated in other vaccination units, but need to carry the first vaccination certificate. Please pay attention to local policies before making an appointment for vaccination.
