Because no one is speaking out about or raising enough cain to get noticed by local government . I'm sorry to hear about your son. The doctor should have known better and not risked using the vaccine. Look about 6 paragraph down this page. Www-rohan.sdsu.edu/~rgibson/smallpox.htm
I'm afraid I am not convinced of that the vaccines are the source of autism, having much experience in that area. Autism was diagnosed around that age long before thermisol vaccines and tends to onset suddenly at a young age. This can explain the terrible change in personality and behavior that many horrified parents describe. Do I believe there is another reason for the prevalence of autism, perhaps, but vaccines are far too vital for us to dismiss. Few studies have revealed any possibilities of ill-effects from mercury. I will not dismiss your beliefs however, because there is always another side and it could turn out to be different than either of us suspected. My deepest sympathies however, I know the pain and frustration.
