A new McGill University Health Center study provides conclusive evidence that the Measles Mumps Rubella (MMR) vaccine is not associated with the development of autism spectrum disorders (ASDs). The study, published in the scientific journal Pediatrics, reveals fundamental errors in previous molecular studies that falsely implicated the MMR vaccine as a risk factor for autism. This study arose from a cross-disciplinary collaboration between Dr Brian Ward, Chief of Infectious Diseases at the MUHC, and Dr Eric Fombonne, Director of Pediatric Psychiatry at the Montreal Children’s Hospital of the MUHC.
All well-conducted epidemiological studies have found no association between the MMR vaccine and autism at the population level. The MUHC team’s new data now demonstrate that the putative MMR-ASD link can no longer be argued even at the level of the individual child with autism.
