Newborn full-term vaccinations can cause fever and other conditions in some babies. Most babies do not have symptoms from the vaccination, and it does not cause fever, rash, hard knots, etc. If your baby has a fever caused by the vaccination, you can reduce the clothes you wear, increase the water intake of the child, ensure that the limbs are warm, and monitor the body temperature. After a period of time, the body temperature will slowly drop to normal. If the child’s temperature does not go down, or if it goes down but rises again, it is recommended to go to the pediatrician of the hospital in time, except for fever caused by infection.
