In China, minors are natural persons under the age of 18, and most of the vaccinations in China are completed before the age of 7, when parents or guardians and other family members are always required to accompany them due to their young age. Vaccination In addition, if a minor is suffering from a serious chronic disease or acute infectious disease, or has fever or diarrhea before vaccination, the vaccination should be delayed. Avoid taking anti-inflammatory drugs, fever-reducing drugs or drinking alcohol before vaccination to avoid affecting the effect of vaccination. During the vaccination process, it is recommended to wear loose and comfortable tops and to stay for 30 minutes after the vaccination is completed before leaving in order to deal with allergic reactions or other symptoms that occur after vaccination. Do not rub or press the needle holes after vaccination to avoid aggravating the swelling symptoms. You should also pay attention to rest and keep the area dry. Do not take a shower on the day of vaccination to avoid contamination of the needle holes and infection. Avoid eating spicy, cold, greasy and allergenic foods such as chili, seafood, beef and mutton before and after vaccination to avoid aggravating or triggering adverse reactions.
