CDC and Columbia find no link between autism and MMR vaccine

According to this post at the Wall Street Journal Health Blog, the Center for Disease Control and Prevention and Columbia University did a study that found that there is no connection between the Measles, Mumps and Rebella vaccine and autism.

The two researchers conducted a study based on:

The measles virus from the vaccine could reproduce in the intestinal tract, leading to inflammation and bowel permeability. That leaky bowel could permit the release of chemicals that would make their way to the nervous system, causing trouble.

When conducting the research, they looked at children with gastrointestinal problems who had autism and children with gastrointestinal problems with no autism. Studies showed there was no difference between the two sets of children.
