I'll be sixty soon. (boo.) We got the vaccines, too, but not in the several combinations that exist now. I wouldn't not vaccinate my child, I'd just do it one at a time, spaced over time. It may be the bundled immunizations that are causing problems, and if there is a problem, there's no way to tell which one is the culprit.
However, I'm not a scientist nor have I stayed at a Holiday Inn lately.
