The story of the secret Simpsonwood meeting, the CDC’s subsequent fraudulent studies, Congressional investigations and the National Institute of Environmental Health Science’s analysis of the CDD’s research is well documented. However, what is less known is the CDC’s attempts to avoid answering many NIEHS and Congress’s complaints. In a letter to Pediatrics, Dr. Ken Stoller, a UCLA pediatrician and a former fellow of the AAP, noted how then CDC Director Dr. Julie Geberding in the final moments under pressure to give account for the CDC’s wide range of errors in its study stated, “CDC concurs that conducting ecologic analysis using VSD administrative data to address potential associations between thimerosal exposure and the risk of autism spectrum disorder is not useful.”
And here is the rub. Every study the pro-vaccine community quotes to discredit a thimerosal-autism association is either an ecologic study (investigating and comparing statistics between one or more populations) or cohort study (looking at risks or illness in the history of a group or population). Both types of studies are inferior to controlled studies looking at medical conditions in vitro or in vivo. Neither do they follow sound scientific protocol in order to draw definitive conclusions. Moreover, the most frequent criticism of ecologic and cohort research is the wide scope of deceptive data manipulation such studies lend themselves to in order to arrive at the researcher’s desired result. For example, in CDC studies, the agency has never compared autism rates in vaccinated children with a population of children who were unvaccinated or had not received mercury laced vaccines. The lack of such a study should have been a no-brainer for the AAP.
Not a single study in the vaccine industry’s arsenal is biologic. The federal health agencies refuse to conduct convincing biologic studies to bring the thimerosal-autism debate to closure. The reason is simple: there is not an ounce of evidence that such studies would conclude in their favor, otherwise such research would have been performed during this decades long argument.
Nevertheless, independent biologic studies have shown repeatedly that thimerosal is linked to neurological degeneration, including autism, Asperger’s, ADD and ADHD, tics and seizures, etc. A recent review of all thimerosal research recorded in the National Institutes of Health publication database, PubMed, by the Faculty of Health Sciences at the Universidade de Brasilia in Brazil determined that the biologic data reveals 1) low doses of thimerosal against isolated human and animal brain cells found in all studies characteristic mercury neurotoxicity, 2) there has yet to be studies showing the neurotoxic effects when thimersosal is combined with aluminum, another neurotoxic chemical and common vaccine ingredient, and 3) animal studies show that thimerosal exposure leads to the accumulation of inorganic mercury in the brain.
