Recall bias, MMR, and autism.

چکیده
Parents of autistic children with regressive symptoms who were diagnosed after the publicity alleging a link with measles, mumps, and rubella (MMR) vaccine tended to recall the onset as shortly after MMR more often than parents of similar children who were diagnosed prior to the publicity. This is consistent with the recall bias expected under such circumstances.

متن کاملMMR-vaccine and regression in autism spectrum disorders: negative results presented from Japan.
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 significant difference was found in the incidence of regr...
متن کاملMMR vaccination and pervasive developmental disorders: a case-control study.
BACKGROUND Concern that measles-mumps-rubella (MMR) vaccination might cause autism has led to a fall in vaccine coverage. We investigated whether MMR vaccination is associated with an increased risk of autism or other pervasive developmental disorders. METHODS We did a matched case-control study using the UK General Practice Research Database. Cases were people born in 1973 or later who had f...
