I heard a girl talking on the radio this morning. She had just got over mumps, as had most of the people in her halls of residence at university (think she said she was in Cheltenham).
She had the MMR and the booster, so did most of her peers.
This girl's GP said, "The MMR doesn't work". Is he wrong?
DS is 14mo and hasn't had the MMR. Given that it would seem it's no good, why should he?
