Does anyone know how long maternal immunity lasts?

Our HV said it 'starts to wear off from 12months' but when is it gone completely?
I'm having to weigh up risking taking an as yet unvaccinated (MMR) 14 month old to France next week where they have a measles epidemic. Will he still have some protection from me? He is still breastfed, but I'm not sure that makes much difference...

i have read that' it's around 10 months onwards

basically it's when their own immune system kicks in properly, so definitely from 12 months if not earlier

i don't think a 14 month old would really have any immunity from you at all, even if breastfed

Dd2 got chicken pox at 6 months when she was still being breastfed entirely. And yes, I know I've had chickenpox as I had it badly at college.
