Our daughter broke out with the rash from her 1st MMR shot. She is now due for her 2nd MMR shot. #1 question. Should she receive a second MMR. #2 question Will she break out with a rash again and will it be worse?
About one person in 20 gets a rash after the first dose of MMR vaccine. It may occur again after the second dose, but that is less common and usually milder, not worse.
