MMR - when to give

[susanmt]

I am NOT looking for a fight!
I am pro MMR and my dd had it with no problems. But I have come accross some things on Mumsnet recently suggesting that it should be given later rather than earlier in order to maximise immune response. We had dd immunised at 14 months as we were going to a large church conference in the south of England and I was worried about her being exposed to non-immunised children. At that point I'd not heard anything about late immunisation. But ds's appointment came in today and he was only 13 months on Monday, and the appointment is for Wed. I would rather wait a few months if it is likely that his immune response to the jab (which he will have, no doubt abou that) will be better.
Does anyone have any really solid evidence to back up the idea that jabs given later have a better response? Thanks

Whether or not MMR will work first time round depends a lot on how many maternal antibodies the baby still has. If there are a lot they will "attack" the vaccine before it their body has a chance to produce it's own antibodies. There isn't really a way to tell how many antibodies there are in advance it's all a bit of guesswork. The main problem seems to be the measles component (probably becaus babies get a stack of antibodies fro their mother). Leaving it later makes it less likeyl maternal antibodies will still be floating around but like anything to do with vaccinations it;s not written in stone.

Mears - sorry if I'm being dense here, but is it only the case that b/f children respond better if they are still being b/f or do they respond better if they had been breastfed at any point? I b/f DS until 8 months but have now stopped.
Thanks

At any point kyliebump. Still haven't managed to find the article. Sorry.
