The kindergarten recommends the new coronary vaccine, which is intended for people over 3 years of age with no contraindications to prevent infection with the new coronary virus. The age of eligibility for kindergarten is generally 3 to 6 years old, but at present, the vaccine has been expanded to include children from the age of 3 years old, so it is mandatory for kindergartens to receive the New Crown vaccine. However, the prerequisite for this vaccination is the absence of contraindications, such as allergy to the components of the vaccine, acute exacerbation of a chronic disease, being in the middle of a fever, and so on. The new coronavirus vaccine is a public product and is currently free of charge for the whole population in China. This vaccine is mainly used to prevent the disease caused by the new coronavirus infection, i.e. the new coronavirus pneumonia. If you have not followed the normal vaccination program, you need to catch up the vaccination as soon as possible and do not need to start again. In addition, some people may experience adverse reactions such as headache, fever and fatigue after vaccination. To summarize, it is necessary to strengthen daily life management, take various protective measures and actively receive the new coronavirus vaccine in normal times. Tip: “New coronavirus pneumonia” and “new coronavirus pneumonia” mentioned in this article were renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
