Well, as a mom who watched her son regress into autism after his routine shots, I obviously have strong opinions on this issue. I am not anti-vaccine, but I do think there are too many given at once. Also, thimerisol is not the only troublesome ingredient in vaccines - there is aliminum, formalgahyde, fetal tissue, and many others.
An excellent book to help you make this decision is "What Your Doctor May Not Tell You About Childhood Vaccinations" By Dr. Stephanie Cave. She outlines the risks of both the disease and the shots and also offers a possible alternate schedule.
For example, did you know that Hep B is a blood born disease that you only catch from sharing needles or unprotected sex? Why do we give this to infants? The theory is they are less likely to come in for this shot when they are teens and are at risk. Also, if the mother has Hep B she could pass it to her child by breastfeeding. So - you have to decide if there is a chance your child will contract this or if you can wait until they are closer to becoming sexually active.
Also - there is still trace amounts of thimerosal in the shots and a full 25 micrograms in the flu shot. So - your child is still exposed to mercury through these shots. You have to decide what exposure of mercury you are comfortable with.
Also - there is an alternate theory that has nothing to do with thimerosal. The MMR has never had thimerosal, the problem with it is that it is three live viruses at once. Some children who have regressed into autism have live measles virus in their intestines. More research needs to be done, but it is disturbing to see this.
So - you are right to proceed with caution, talk it over with your doctor and read as much as you can.
