Re-analysis of CDC Data on MMR Vaccine and Autism

Breaking News

December 10, 2018

After four long years, Dr. Brian Hooker’s reanalysis of the CDC’s MMR-autism data from the original Destefano et al. 2004 Pediatrics paper has been republished in the Winter 2018 Edition of the Journal of American Physicians and Surgeons.

The data, when properly analyzed, using the CDC’s own study protocol, show a strong, statistically significant relationship between the timing of the first MMR vaccine and autism, specifically in African American males. In addition, a relationship also exists in the timing of the MMR vaccine and those individuals who were diagnosed with autism without mental retardation.

These relationships call into question the conclusion of the original Destefano et al. 2004 paper which dismissed a connection between the MMR vaccine and autism.

Its not a reanalysis. It’s his opinion about a lost opportunity. Do repeat the research and see what the findings are.


Do you understand words “statistical significant”? That’s more than correlation!


I have Asperger’s, and I know that I have been different since the day I was born. I watch videos from my birth up to immunization time and see that I was never typical. A strong level of significance still does not equal causation in this case. Either way, I love who I am and would rather be autistic than sick!


many researchers use the word “significant” to describe a difference or relationship that may be strategically important to a client (regardless of any statistical tests). In these situations, the word “significant” is used to advise a client to take note of a particular difference or relationship because it may be relevant to the some strategic plan.
