Yep. MMR is measles mumps rubella. Its one you got when you were about 2. Its one that causes that scar we all have. (cept now they do babies on the bum I think). I know when I started college I had to have an MMR booster.

I think MMR is measles, mumps and rubella, but I'm not a doctor.

Shots in general don't hurt (although I personally hate tetanus shots, the poke itself doesn't hurt but my arm feels really sore for a few days after). Just a quick little sting, not too bad. Look away and it's over before you know it.
