Normal life can be carried out after the New Crown vaccine. If there is a need to wash the hair, it is usually possible to do so, but the vaccination site should be kept clean and dry to avoid causing local inflammation. In addition, it is not recommended to wash the hair if the patient has symptoms such as fever, dizziness, headache, and weakness due to immune response after New Crown vaccination to avoid getting cold and aggravating the above-mentioned adverse reactions. After 2-3 days of vaccination, if the body does not have special symptoms such as fever, weakness, cough, headache, etc., head cleaning can be performed according to the patient’s needs, but after washing the hair, care should be taken to dry it or blow dry it in time and pay attention to keeping it warm to avoid going out with wet hair or going to bed with wet hair that may cause cold and flu, and to avoid other upper respiratory tract infections that may aggravate physical discomfort. It is usually recommended to avoid getting water on the vaccination site for 24 hours after the vaccination, to take more rest for 3 days, to reduce heavy physical work and highly stressful work, and to avoid drinking alcohol as much as possible, as alcohol may affect the active ingredients in the vaccine, thus reducing the efficacy of the vaccine and affecting antibody production. In addition, you should also pay attention to a light diet after vaccination, avoiding spicy, stimulating, greasy and cold foods to improve the immunity and safety of the vaccine and reduce the possibility of adverse reactions after vaccination.
