Vaccines and Autism
The debate over whether autism spectrum disorders are caused by vaccines started in 1998 when the medical journal The Lancet published a now-retracted study by researcher Andrew Wakefield linking the MMR vaccine to autism.
Most of Wakefield's co-authors withdrew their names from the study when they learned he had been compensated by a law firm intending to sue manufacturers of the vaccine in question. In 2010, Wakefield lost his medical license. In 2011, the Lancet retracted the study after an investigation found Wakefield altered or misrepresented information on the 12 children who were the basis for the conclusion of the study.
Other researchers have not been able to replicate Wakefield's findings. Several subsequent studies trying to reproduce the results have found no link between vaccines and autism, including several reviews by the Institute of Medicine.
Timeline
Early 1900s - Autistic characteristics are studied as symptoms of schizophrenia.
1938 - Donald Gray Triplett of Mississippi is first examined by child psychiatrist Leo Kanner of Johns Hopkins Hospital and later becomes the first person diagnosed with autism symptoms.
1943 - Triplett is identified as "Donald T." in the paper "Autistic Disturbances of Affective Contact" by Kanner. The paper elaborates on the idea that autism is related to lack of parental warmth; this is later dubbed the "refrigerator mother" theory.
1944 - Hans Asperger, an Austrian physician, publishes a paper about autistic syndrome. The paper gains wider recognition when it is translated into English in the early 1990s.
1964 - Bernard Rimland, a research psychologist, publishes "Infantile Autism: The Syndrome and Its Implications for a Neural Theory of Behavior," which contradicts the "refrigerator mother" hypothesis. Kanner is the author of the foreword.
1965 - Rimland founds the National Society for Autistic Children (now the Autism Society of America). He later establishes the Autism Research Institute.
1980 - Autism is classified separately from schizophrenia in the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III).
December 18, 2007 - The United Nations adopts a resolution declaring April 2 World Autism Awareness Day.
October 29, 2014 - The medical journal Nature reports that scientists have identified 60 genes with a greater than 90% chance of increasing a child's autism risk.
December 17, 2015 - Scientists at Harvard and MIT announce they have found, for the first time, a link between autistic behavior and reduced activity of a key neurotransmitter, a type of brain chemical that enables the transmission of signals across neurons, allowing the brain to communicate with other organs.
