The third dose of New Crown vaccine can still be continued beyond one year, but the protection is weaker than that of the vaccination within the specified period. The third shot of New Crown vaccine belongs to recombinant protein vaccine, which requires that the third shot of New Crown vaccine needs to be completed within 6 months after the completion of the first shot, and there is no special requirement for exceeding the time of vaccination, so it is also recommended to make up the vaccination in time under the doctor’s advice if it exceeds the time of one year. If you have not received the third vaccination for a long time after the second vaccination of New Crown vaccine, your body’s ability to fight against diseases will decrease, and the third injection of recombinant protein vaccine can effectively increase the body’s ability to fight against the virus. It is recommended that you try to finish the New Crown vaccination within the prescribed time, so that the protective effect of the vaccine can be better enhanced, and you also need to pay attention to personal protection in your daily life. If you do not receive the vaccination within the prescribed time, you need to make up the vaccination in time and consult the physician at the vaccination site for advice before vaccination.
