Parents of children should not be anxious as some children may develop fever after vaccination. In this case, the child should be given plenty of water and physically cooled by wiping with warm boiled water for 10-20 minutes. If your child’s temperature continues to rise you will need to take oral antipyretics first and see your doctor promptly for relevant investigations such as a full blood leukocyte check and rapid C-reactive protein to determine the next step in treatment.
