In this study, researchers compared children had had and had not gotten the measles, mumps and rubella vaccination. The study identified four hundred and ninety-eight cases of autism, including core autism, atypical autism and Asperger syndrome in children born in the United Kingdom since 1979. There was an increase in cases of autism by year of birth with no change after the introduction of the vaccination. There was also no age difference at diagnosis between the cases vaccinated before or after eighteen months of age, when the vaccination was distributed, and children that were never vaccinated. These results showed no temporal association between the onset of autism within one or two years after being vaccinated with MMR. In addition, developmental regression was not clustered in the months after vaccination. The data from these results does not support the connection between MMR and autism and if an association was to occur, it was so rare it could not be
