My 3 month old baby doesnt get fever after vaccine. He dint get fever for the 2 and a half month vaccine and also for 3 and half month vaccine. This means that baby doesnt have immunity?? Help me clear this doubt

A. hi, do check that your baby received painless vaccine previously,Fever soon after vaccination is normal and it subsides within a day or two. If this happens talk to your doctor and give your baby the right medication. try to dream feed .
