Elementary school students are not allowed to receive the third booster shot of the New Crown vaccine.

And after two shots of the new crown vaccine can produce antibodies in the body, but also can greatly reduce the chances of infection of the new crown virus, the later need to be vaccinated to patiently wait for the official notification. In addition to elementary school students, pregnant women, asthmatic and febrile patients are also not allowed to receive the third booster shot of the vaccine, and can only receive the vaccine after they have been cured of any related illnesses.
