i blieve MMR vaccine needs to be a given a month prior to traveling for it to 'kick in.'
also i would split the MMR, as well as give chicken pox some other time (i have never had my kids get chicken pox, just opted out of that one). are you going overseas? if yes, i suggest delay the trip for another month and give the shot in two starting sometimes next week.
ps Anne-marie F: one cannot avoid the autism/vaccine issue. it is a scary thought for millions of parents. the two always go together whether founded or unfounded.
