The autism rates of been on the rise for years and though there are many theories, there are no definite explanations to the increase of cases.
On December 1st, 2009, in the Pediatric Infectious Disease Journal, a report was released comparing cases of Autism with the MMR (Measles-Mumps Rubella) Vaccine. Some earlier cases suggested an association between the two, while other studies showed otherwise.
In this newest, small scale study, there were 96 autism cases of children from ages 12 to 15, and 192 healthy children matched to cases by birth year and sex. Other factors in the study included mother’s age, medication during pregnancy, generation time, and perinatal injury in the analysis and it was found MMR vaccine was not linked to increased risk of autism.
Of children vaccinated before diagnosis, those who were vaccinated with MMR were at 83 percent reduced risk of autism and those vaccinated with single measles vaccine were at 56 percent reduced risk compared to those who were non-vaccinated.
Vaccinated children were at 72 percent reduced risk of autism compared to those who were did not receive measles vaccine.
The researchers concluded that “the study provides evidence against the association of autism with either MMR or a single measles vaccine.”
