You can take a normal bath 72 hours after a child is vaccinated, because within 72 hours after a child is vaccinated, the vaccination site has not yet healed completely. If you give children a bath, it is easy to cause skin infection at the vaccination site, causing local redness, swelling, heat, pain and other symptoms, so it is more appropriate to give children a bath 72 hours after the vaccination. If you give children a bath too early, it will also cause easy to get cold, which will cause an increase in the number of adverse reactions to vaccination. Children who get cold will have nasal congestion, runny nose, sneezing, and the effect of the child’s vaccination will be reduced.
