These researchers examined autism diagnosis and vaccination histories (vaccinated with the MMR vaccine, vaccinated with a single measles vaccine, or not vaccinated) in 288 children, 96 with autism and 192 healthy controls. Results demonstrated that autism risk was not greater in the vaccinated children compared to the children who were not vaccinated. These results provide some evidence against the link between the measles virus and autism.
