Uchiyama, Tokio; Kurosawa, Michiko; Inaba, Yutaka – Journal of Autism and Developmental Disorders, 2007
It has been suggested that the measles, mumps, and rubella vaccine (MMR) is a cause of regressive autism. As MMR was used in Japan only between 1989 and 1993, this time period affords a natural experiment to examine this hypothesis. Data on 904 patients with autism spectrum disorders (ASD) were analyzed. During the period of MMR usage no…

Somewhat more abstractly, shifting governance patterns afford researchers an excellent opportunity to test…
