So I went to the CDC website and spent some time digging around before I found this PDF document that discusses studies on the safety of Vaccines and Autism:
There are many studies referenced in this PDF, so I decided to start with the first one:
“Increasing Exposure to Antibody-Stimulating Proteins and Polysaccharides in Vaccines Is Not Associated with Risk of Autism”
Frank DeStefano, MD, MPH , Cristofer S. Price, ScM , and Eric S. Weintraub, MPH
Before I go into the details of this first study, I just wanted to directly quote a line from the CDC pdf, which in big letters at the start of the document states the following:
“The evidence is clear: vaccines do not cause autism spectrum disorder (ASD). This fact sheet provides a summary of studies that were conducted by CDC or with CDC’s involvement.”
So, here is a link to the first referenced study:
It was published in the “Journal of Pediatrics”, Volume 163, number 2 – August 2013.
So the “control” was a group of children that did not have autism or anything on the spectrum and the “test” group was called the ASD Control. Correct me if I am wrong, but isn’t this logic backwards? If we are testing to see if ASD occurs in a group, should we not know whether or not the control and variant groups have ASD and determine that by the experiment?
Just go to page 564 and 565 of the pdf document (it starts on page 561). On those pages are shown the number of ASD cases vs control cases of children based on 3 time periods:
- Birth to 3 months
- Birth to 7 months
- Birth to 2 years
Interesting… Smoking Gun?
The smoking gun however, is that as they compared one group of children that received a similar amount of vaccines as another group of children. In other words, both groups were fully or almost completely vaccinated!
Just look on page 564.
- birth and 3 months
- birth and 7 months
- birth and 2 years
- no under-vaccinated children in either group
- no unvaccinated children in either group
- no difference in vaccination rates of children studied
