The first dose of the new coronavirus vaccine was not administered can be registered through the community or village council, or the local CDC to make an appointment. Due to the current incidence of the new coronavirus disease, we have provided answers in conjunction with the new coronavirus vaccine. For those who did not get their first dose of the new coronavirus vaccine, you can make an appointment to get vaccinated again if you are 3 years of age or older and are eligible to be vaccinated. Wear a good mask, bring your ID card, inform the doctor of your condition before vaccination, and ask about contraindications to vaccination. In addition, after the first vaccination, you need to stay for about 30 minutes before leaving to avoid adverse reactions. Avoid strenuous exercise within 24 hours after vaccination, avoid touching water in the vaccination area, and still need to do a good job of personal protection when going out to reduce the incidence of disease.
