How to avoid baby from fever after injection?

Fever after injectio. Your question is too vague, if you intend to ask the fever after immunisation shots. We give multiple shots at the same visits starting at birth in the hospital we give hepatitis b and after that at 2, 4, 6, 12.15.Months other shots are given, most of the babies do not have any fever like reaction, but rarely it may happen and there is no way to predict or prevent it, unless you know what caused it.
