As many of the responses pointed out, this is a topic that people appear to feel strongly about one way or the other. Many states have passed laws that don't give parents the option on whether to vaccinate or not - at least if you want your child to attend public school.
As a holistic health practitioner, here is my opinion. I do not believe it is the vaccination itself that is harmful, I believe it is the suspension agents used in the formulations. When a toxin like mercury is given to a new born or very young child that has not had the opportunity to develop their immune system, bad things can happen. Some physicians offer vaccinations that do not contain these toxic suspension agents - but you have to ask for them. The law may require you to vaccinate your child, however, you do have the right to space out those shots. Making this choice gives your child's body the opportunity to eliminate the toxins before more toxins are given. I know it's not convenient, but spacing out even 2 weeks apart is better than overloading their immune systems and causing a potential toxic reaction.
Look at it this way, if you compare the amount of toxins in the grouped vaccinations - sometimes up to 6 shots - and compare those ppm (parts per million) to the child's weight - you can see how toxic overload happens. One MD said a fair comparison would be the toxins in 6 shots would equal 70 shots in an adult.
As far as the comments regarding whether vaccines cause autism or any other disorder, the jury is still out on that one. I just have a hard time believing that if there are no dangers to these vaccines then why is it illegal for a parent to sue a vaccine company and why does the government have a slush fund to cover claims filed by parents.
