We have a 4 1/2 year old autistic son... did mercury in the vaccines cause it? I don't know, but I now have very strong feelings about vaccinations regardless of the thimerasol issue.
In my opinion, many of the vaccinations are not neccesary. Chicken pox? We probably all had it and turned out fine. Polio? The odds of your child contracting this are very slim unless you travel internationally where it is still prevalent. In my pediatrician's office, there is a poster that gives the importance of vaccines and the statistics of how many cases of polio, mumps, measles, rubella, etc. there are in the US each year. To me, the VERY LOW (some almost non-existent) number of cases is not worth the chance of a "typical" child becoming a specials needs child.
Our oldest son has not received vaccines past two years old and we now have two other children who have only received the vaccines for meningitis. We lost a part of our first son to autism and I don't want to take that chance with my other two.
Vaccinations are a personal decision. All you can do it be educated and follow your heart!
