You can’t drink alcohol for three days after hepatitis B vaccination, and you can’t drink alcohol until at least one week after hepatitis B vaccination. Because alcohol is metabolized in the liver, if you drink a lot of alcohol after hepatitis B vaccination, it may cause the effect of hepatitis B vaccine antibody production to be affected, which will affect the potency of hepatitis B vaccine antibody, so it is recommended that you drink alcohol at least one week later, which is more appropriate. Meanwhile, after the injection of hepatitis B vaccine, you should pay attention to the light diet, avoid taking spicy and stimulating food, avoid strenuous exercise, and also avoid some foods that may produce allergies. Avoid contact with water within two days after hepatitis B vaccination to avoid wound inflammation and infection.
