My daughter was diagnosed with Autism at 3 yrs old. Looking at home videos, she seemed normal pre-vaccination. Years of therapy and a strict Gluten & Casein free diet helped her to overcome much of the learning issues she had. I've been blessed she's come this far.

Do not vaccinate your children under any circumstances. If you have to, claim a religious exemption, just don't do it.

If you still feel strongly about vaccinations, at the very least do not give them the MMR "cocktail", but rather spread the individual shots out over several months. Trust me, your child won't die of Measles by waiting a few months!

Also, camera phones are ubiquitous, so take several hours or days of video before and after each vaccination.
