Dr. Paul Offit comments on robust new study confirming, again, that vaccines do not cause autism

Published September 28, 2015 in Proceedings of the National Academy of Sciences

On Monday, September 28th, yet another study was published, this time in the prestigious journal, the Proceedings of the National Academy of Sciences (PNAS), demonstrating yet again that thimerosal is not related to autism behaviors or to neuropathology in an animal model.

Researchers Studies using donated post-mortem human brain tissue have allowed researchers to learn what the brains of people with autism look like. Therefore, researchers in the current study were able to determine that monkeys exposed to vaccines with thimerosal did not show these changes.

On Tuesday, September 29th, ASF Board Member Dr. Paul Offit published a short commentary in PNAS, explaining, in part, "The fear that vaccines cause autism has been a tale of changing hypotheses: first, involving the measles–mumps–rubella (MMR) vaccine followed by thimerosal, an ethyl Mercury containing preservative in vaccines, and, most recently, the number and timing of vaccines. The primate study by Gadad et al. (1) addresses all three concerns."

This study was funded in part by SafeMinds and the National Autism Association and is open access.
