Although there is not enough clinical data to prove the effect of strenuous exercise on New Crown vaccination, strenuous exercise immediately after New Crown vaccination is not recommended. If a vaccine recipient exercises vigorously after a New Crown vaccination, the immune function of the body may be altered, affecting the absorption of the vaccine and even increasing the likelihood of adverse reactions, such as the occurrence of fever, vomiting, headache, malaise, and abdominal pain. If a vaccinated person wants to exercise after receiving the new crown vaccine, he can do aerobic exercises such as slow walking and jogging in moderation, which usually will not affect the effect of the vaccine, but swimming exercises are not recommended because swimming may cause infection at the eye of the vaccinated person. Each vaccinated person has different sensitivity and reaction to the New Crown vaccine due to the difference in their physique, so in general, it is necessary to observe the vaccination site smoothly for 30 minutes before leaving the vaccination site after the New Crown vaccine is administered to avoid other adverse reactions. After receiving the New Crown vaccine, vaccinators are advised to keep the injection site dry and clean on the day of vaccination, avoid showering, sitting in the bath and other actions that may cause contact between water and the eye of the needle, and pay attention to personal hygiene to avoid causing infection at the injection site. Avoid contact with known allergens and common allergens for one week after vaccination, avoid drinking alcoholic beverages and eating spicy and stimulating foods, avoid staying up late and pay attention to rest so as not to affect the immunization effect of the vaccine.
