Is there a specific time period to have MMR?

My ds was called for his MMR at our local clinic at 12mth, as he has an egg allergy and there's a chance he could have a reaction (albeit slim chance) it was mutually decided between myself and the practice nurse that it would be better if he had the MMR at the hospital under observation to be on the safe side. This was 4 weeks ago and I've heard nothing from the hospital. He will be 13 months tomorrow, I'm worried the immunisation needs to be given at a certain age or not given at all?

It will be fine. In my area they don't do it until 13m anyway. And adults can have the same vaccine. They also do a catch up for older children if they've missed it earlier on.

You could maybe call the practice nurse or secretary and check the referral has gone off?

Thanks I'm going to chase it up tomorrow I was worried they'd say he was too late for it

Certainly chase it up as the sooner he's protected the better, but he can't be 'too late' for it.

The immune response is much better after 12 months, so they wait until then but give at the earliest possible opportunity thereafter. So 12-15 months. But will happily immunise anyone over that age who needs it!

I had MMR at the grand old age of 34 when changing careers, since despite being pretty sure I'd had a measles jab as a kid, rubella jab as a teenager and suffered mumps in primary school, I couldn't prove it! No ill effects from having it at an advanced age, beyond an unnecessary sore arm
