Beware of Studies Concluding Autism is Not Associated with Childhood Vaccination
Study Design and Conduct Commit Type II Error: Failing to Find a True Association
By Peter A. McCullough, MD, MPH
As an epidemiologist, I can tell you it takes considerable training and scholarship to determine whether or not a study is valid and to determine if the conclusions are supported by the data. When it comes to childhood vaccines, the world is becoming skeptical of the vaccine industry since the CDC ACIP panel has added the EUA unsafe, ineffective mRNA COVID-19 vaccines for infants starting at 6 months of age.
With the ever expanding ACIP schedule of vaccine quantity and intensity of injections there has been a skyrocketing rate of autism. This has triggered scientists to go back and look at the studies published at the time to reassure parents that routine vaccines did not cause autism. Because so many shots are given at once, it is probably not any individual product that is the culprit, rather “hyper-vaccination” of a bundle of vaccine products that invokes a neurotropic, cytokine mediated inflammatory reaction that in some causes febrile seizures, autism, and immediate death. There are factors related to susceptibility including older parents and siblings with autism, but it remains that hyper-vaccination is a likely provocateur.
Madsen et al used Danish automated health data to evaluate the association of the MMR at age 15 months and autism. Only 40/422 had charts reviewed to verify the diagnosis of autism. Because it is an important diagnosis, all 422 cases should have been adjudicated by two blinded expert child psychiatrists. This study was unlikely to find an association from the outset since not all the vaccines where considered as a “bundle” and compared to children who went “natural” meaning completely unvaccinated with any product.
