#asktheexpert Almost a week ago, my baby got a flu vaccination. That time anything happened, but these two days he's having fever and lost his appetite. Also some of his body, some red spots have appeared and even his mouth has got little ulcer too.

A. the child is having post viral or post disease rash and is very common at the end of viral infection. you have to just give plenty of fluids to the child and xgive bath twice daily and if there is itching then only you have to apply calamine lotion and this type of rash goes away in and around 2 tox 3 days
