The medical journal Pediatrics just published research done by the Institute of Medicine to see if any relationship between vaccination and autism could be found.

The researchers at the Centers for Disease Control studied more than 1,000 children and matched controls.  They found no evidence for increased risk for autism due to the preservative thimerosal used in some vaccines, or to vaccines themselves.

Special attention was paid to the measles-mumps-rubella vaccine and, again, no association with autism was found.  In the past two decades the number of children diagnosed with autism has increased.  Also over that time period the number of standard childhood vaccinations has increased.  Hence, the close scrutiny.

Yet, the study adds to a growing body of evidence demonstrating no association between immunizations and autism.
