Should she have MMR before going to Brazil

[LoraB]

We are going to Rio and Buzios for 2 weeks in mid sept for honeymoon with dd, now 12 months. would it be advisable to have mmr before or wait until after we come back.

I would have thought wait until you return. Otherwise when you travel you'll still be in the time period when reactions are most likely (2-6w after the injection IIRC). As for protecting her abroad, the imms won't have had time to 'take' before you go, so she wouldn't be protected yet in any case.
