There are some contraindications to hepatitis B vaccination and no alcohol should be consumed. Before the hepatitis B vaccination, you should first clarify whether you have symptoms of fever and infection. If you have fever, acute illness or symptoms, you cannot have the vaccination and need to delay the time of hepatitis B vaccination. You should not take a bath after hepatitis B vaccination. The needle eye at the injection site has failed to heal and bathing can easily lead to wound infection. After hepatitis B vaccination, you should also pay attention to a light diet and not consume some spicy and stimulating foods, which may easily cause allergic reactions, and you should not drink alcohol. Because alcohol is metabolized in the liver, it may affect the production of vaccine antibodies after the hepatitis B vaccination and affect the effect of the vaccine, and also do not exercise vigorously after the vaccination.
