DD2 is nearly 6 and hasn't had her MMR booster, she was supposed to have it last year, but then we moved and it got forgotten. I recieved a letter yesterday from the GPs saying she hasn't had her MMR booster and I had to phone to book her in. I am unsure about it, because she has lots of allergies and when Dd1 had the booster she had a large reaction to it and I don;t want to put Dd2 through a reaction.
Does she have to have it??
