Try this website from Sunderland University. Paul Shattock who is a director and has spent many years of research, is outspoken. I have been to one of his lectures and he is an amazing bloke. Well worth looking at what he has researched.

My one daughter is diagnosed on the Autistic Spectrum. We beleive that vaccinations were not the cause of her Autism. We bel;eive she had it when born. We had it diagnosed by the age of 3 and have managed to work intensively with her and at 9 she is in mainstream with 1 to 1 support. It is so important to catch it early.
Too many people are jumping on the bandwagon of vaccination, instead of looking back to signs from birth.
Our other daughter is ADHD
