Do any parents of disabled children with nerve damage think that vaccines are the cause of their disability?

It took 6 years for the doctors to come up with a diagnosis for my son. They told me he was going to loose his hearing, eyesight and die. They then spent 7 years trying to find a genetic disorder that would match his symptoms that would lead to death. All of my son's medical tests were NORMAL. Now that I have detoxed him from mercury, tin and arsnic, they say he is not going to die that he is fine. Go figure?
