Yup.. you're meant to have them. Check with your doctor though. I know I was in the first year of MMR, and got a booster when I was still at primary school.. just before I left.. but I didn't remember it so almost ended up having another booster!
I had a meningitis vaccine in 2000 as well and the doctor said I don't need another one. I did have to have an MMR though cos i'd only had 1 before. Rather worried about the huge list of side effects on the piece of paper I was given!
