All the loons who say vaccines cause autism and other issues site a study by a doctor from England that a number of years later admitted he faked his research and manipulated his numbers.
Aside from that one "study", there has not ever been a per reviewed medical study linking vaccines to autism.
I guess that I am a loon, but then again I have seen it 1st hand and have been around this child from day-one to his current age of 15-years old.
As a child he was as healthy as could be determined for his age. He had the DPT shot and things went downhill. He has been diagnosed with low functioning autism.
If you would like to speak with his mother or family, I would be happy to arrange a meeting with them and you can share your extensive knowledge about the lack of evidence between immunizations and autism. They would probably show you the before pictures and after and you can make your own determination.
