M.S.
I did a lot of research on all the immunizations. My gut reaction - most are good even though kids are guinea pigs (most vaccines are tested on very small cohorts before being released to the public). But, bottom line is, my kids got all vaccines - just not on the "correct" schedule. personally, I waited on MMR until their 4th b-day well-child visit. Although any of the diseases in MMR can be dangerous, it is extremely rare for them to be dangerous to children - it is older kids and adults that have the issues. And, since most older kids and adults have either had MMR or the shots, there is quite a bit of immunity conferred by the community - in other words, these are no longer common diseases because of immunization programs. Beware though if you're in a state that doesn't have an opt-out - you won't have a choice with regards to school or day care.
