Getting the jabs is a personal decision. My son had pretty obvious reactions to the jabs, but they weren't overly serious. I got them all, but delayed the MMR until he is in preschool (this september). I am not giving either LO the chicken pox vaccine unless they don't catch it on their own by 8 or so. I gave my daughter her first set of vaccinations last week and she had no side effects at all. My son was very cranky, unhappy, fever, not himself, etc - but I wouldn't have even guessed my daughter even had them done. And she had the additional rotavirus vaccine. I do believe that vaccinations are important - when I was young there were less cases of some of these diseases than there are now because people aren't vaccinating. And after seeing an infant in hospital with pertussis, I never ever want my baby to go through that.
Have you spoken to your doc about it? Does she think the vaccinations may have caused the seizures?
