Thirty minutes after vaccination with the new coronavirus vaccine, if there are no uncomfortable symptoms, exercise can be performed appropriately and generally will not affect the effectiveness of the vaccine or cause adverse effects on the body. However, care should be taken not to engage in water contact sports such as swimming after vaccination to avoid infection of the injection site. In addition, it should be noted that strenuous exercise or excessive exercise should be avoided, because a lot of sweating may cause catching a cold and cause uncomfortable symptoms such as cold and fever. Generally, after vaccination, it is necessary to stay at the vaccination site for 30 minutes. During the observation period, attention should be paid to observe whether acute allergic reactions to the vaccine occur, such as high fever, vomiting, fainting, shock and other manifestations. If there is no discomfort at the end of the observation period, exercise may be performed appropriately. Transient uncomfortable reactions such as fever, headache, fatigue, muscle aches, abdominal distension, nausea, vomiting, diarrhea, local hard nodules, slight redness, pain in upper limbs or allergic urticaria may occur after vaccination with New Crown vaccine. If the symptoms are severe, it is recommended to contact the vaccination site for active treatment accordingly. If the symptoms are mild and can be relieved in a short period of time, try to work and rest regularly, avoid staying up late and reduce exercise. Drink more water, eat a light diet, avoid spicy and stimulating foods, and wait for the above symptoms to improve before exercising appropriately.
