Autism arises from a combination of genetic, environmental and medical factors — but multiple vaccines given during the early years of life is the most significant modifiable risk factor for the onset of autism spectrum disorder or ASD, according to a new report by the McCullough Foundation.*
The 82-page report, published Monday, reviewed over 300 autism studies that examined possible causes of autism, including genetic, environmental, toxicological and vaccine-related causes.
Of the studies, 136 focused on routine childhood vaccines or vaccine ingredients, and 107 (79%) of those identified links between vaccination and autism or other neurodevelopmental conditions.
Twelve of the studies compared fully vaccinated and completely unvaccinated children. All found better health outcomes among the unvaccinated group. [See link below].
