I would check Dr. Mercola's website, or read the book "A Shot in the Dark". This is a very important decision, and once a shot is given, it can't be undone - so don't let yourself be rushed.
Also, it is wise to evaluate all of the shots individually. It doesn't need to be an "all or none" proposition. For example, when they came out with the chicken pox vaccine, my pediatrician had concerns because it gave 10 years of immunity - delaying cases of chicken pox to an older age when complications are much more likely. Some vaccines are not worth the risk - unless you can't afford to miss work for a week, there is no reason to vaccinate against a common childhood disease that actually strengthens the immune system.
The person who commented on unvaccinated kids giving her vaccinated kids chicken pox might be interested to know that a vaccinated child gave my unvaccinated child the chicken pox. My child's case was much milder than the vaccinated child's case.
Anyway, it must have been an inconvenience to get chicken pox on a vacation, but the bright side is that now her kids are truly immune for life.
