Major public health organizations, courts all the way up to the Federal Circuit, and even the journal that published the fraudulent paper that initially set off the MMR vaccine scare, all agree that vaccines do not cause autism.
In a study of 95,000 children, researchers were unable to find any association between the measles, mumps rubella (MMR) vaccine and autism. The researchers also examined whether each child had a family history of autism; even for children within this high-risk category, they found no association between MMR and autism.
Not that we needed this study to prove it, there has never been a single high-quality scientific paper to suggest a connection between vaccines and autism. Yet, over the past 15 years, numerous studies have examined vaccines and their ingredients, and consistently found them safe and effective.
