My son is twelve and we've just had a letter inviting him along to be immunised with the MMR in March. He already had it at 12 months and then at his pre-school jolly. Does he need it a third time or is this a cock up?
(Surgery is closed and I won't be able to ring them from work. It will take heaven and earth to get him to the surgery at the appointed hour in a couple of weeks and I don't understand why we've been asked!)
TIA!
