It is generally recommended to take a shower only after 24 hours after vaccination. To avoid infection of the wound, it is recommended to take a bath 24 hours after vaccination. After bathing, it is necessary to pay attention to the treatment of the wound by applying a small amount of iodophor to the wound surface with a cotton swab to disinfect it. In addition, the body’s immunity will be slightly reduced after vaccination, so it is not recommended to contact raw water at this time, and it is necessary to dry the water on the body in time after bathing to prevent catching a cold. If there are local allergic reactions such as redness, swelling and rash after vaccination, you should not take a bath on the same day, otherwise it will aggravate the local symptom reaction. Some babies may have diarrhea, fever and crying after vaccination, so parents should calm their children and take physical cooling or even antipyretic drugs if they have fever. In short, after vaccination, follow the doctor’s advice, pay attention to protecting the wound, take rest, and avoid eating spicy and stimulating food.
