well, I can tell you that there is inconclusive evidence wrt MMR and Autism.
Here are 2 FAQ I took from American Association of Pediatrics website:
What Parents Should Know About Measles-Mumps-Rubella (MMR) Vaccine and Autism
Q. Is there a link between measles vaccination and autism?
* No, there is no scientifically proven link between measles vaccination and autism.
* Extensive reports from both the American Academy of Pediatrics, the Institute of Medicine and the Centers for Disease Control and Prevention conclude that there is no proven association between Measles-Mumps-Rubella (MMR) vaccine and autism.
* Autism is a chronic developmental disorder, often first identified in toddlers from age 18 months to 30 months. MMR is administered just before the peak age of onset of autism. This timing leads some parents to mistakenly assume a causal relationship. There is no evidence that MMR causes autism.
* Increasing evidence indicates that autism is determined while the baby is still in the womb, early in the pregnancy.
Q. What are the complications of measles vaccination?
* Measles vaccine is safe; most people have no reactions.
* About 5 percent to 15 percent of vaccine recipients may develop a fever five to 12 days after MMR vaccination. The fever usually lasts one to two days and usually is not associated with other symptoms. About 5 percent of MMR recipients may develop a rash one to two weeks after immunization.
* Central nervous system disturbances, such as encephalitis, have been reported with a frequency of less than one per 1 million doses of MMR vaccination administered, a frequency many times lower than the incidence of serious central nervous system disorders that follow natural infection at a rate of one per 800.
