I will spend a little time countering. Can't have misinformation kicking around
For fun I decided to take a critical look at the the first 3 studies provided in the 40 papers.
Study #1 - This was too easy. Remember this study? We had a huge discussion on it when it came out. http://jpeds.com/webfiles/images/journals/ympd/JPEDSDeStefano.pdf entitled Increasing Exposure to Antibody-Stimulating Proteins and Polysaccharides in Vaccines Is Not Associated with Risk of Autism
The thread is huge, and I am not going to rehash it again, but here is Dr. Sears rebuttal, which I agree with:
Dated March 29
"I pretty much only have one major criticism of this study. You would probably find the exact same results no matter what group of kids you studied. Pretty much all children in any given span of years receive the exact same number of shot antigens. (By the way, an antigen is simply a protein or sugar germ-related ingredient in a vaccine – some vaccines only have a few, some have many.) Virtually all kids WITH autism have had the same shots as kids WITHOUT autism. So, why would it even be useful to study this? You’ll get the same results every time, whether you study 1000 kids or 100,000 kids. They all get the same shots on the same schedule. They would have gotten the same results if they’d studies asthma, cancer, or any other chronic problem. All this study proved is that all the kids in that HMO got about the same vaccines over that 5 year time period. This doesn’t give us any useful data on how vaccines would have or would not have influenced the rate of autism."
There are a number of issues with the second study. A major one is that it is not about autism. The study looked at how children performed on a variety of cognitive ability type tests and charted them according to how timely their vaccination was. There were virtually no kids (9 out of about 1000) who were completely unvaxxed intentionally. They considered more than 30 days a delay in vaccination. If anything, I think the study demonstrated that among neurotypical children, those whose parents were organised and were able to get to appointments on schedule were more likely to have children that perform well on tests than children who come from a more chaotic background. Geesh - what a surprise.
#3. Not about autism!
"Comparing infants with inborn errors of metabolism (n = 77) versus matched control subjects (n = 1540), similar proportions were up to date for vaccines at 2 years of age, and there was no evidence of delay in receipt of recommended vaccines during the first year. Vaccination of children with inborn errors of metabolism (n = 271) was not associated with any significant increase in emergency-department visits or hospitalizations during the 30 days after vaccination. Secondary analyses suggested that there may be increased rates of hospitalizations 2 weeks after vaccination for the sickest 1- to 4-year-old children."
Bonus - cuz I got bored:
#4 study on post vaccine seizure rate of MMR versus MMRV in 4-6 year old. So related to autism - NOT.
