No. No evidence at all for mmr, or any vaccine, being causative for autism. And, plenty of evidence to the contrary. (nice question from a 2 year-old, and very relevant, but now get going and get your parents to catch you up on your vaccinations. You are overdue, and mumps, measles and rubella are problematic diseases that could have serious effects).
No. No valid evidence has linked MMR to autism. A study in a british medical journal by a dr.Wakefield drawing an oblique relationship of measles vaccine to autism was found to be fraudulent. Dr. Wakefield misrepresented himself and his data. Repeated studies subsequently have disproved any relationship of the MMR to autism.
