Patient's question:
NoDoctor's answer:
It is likely due to a vaccine reaction. The DTaP vaccine can cause a fever. You can start by giving your baby some warm water. If the fever is caused by a vaccine reaction, it usually subsides after drinking warm water. If the fever does not subside or the temperature continues to rise, you need to go to the hospital for a blood test to rule out coincidental colds or other diseases causing the fever.
