New study finds no link between 'too many vaccines' and autism

[proverbialwisdom]

58. Unsupportable and unsustainable given the current health trends. Wait and see.

Dr. Jon Poling to Dr. Steven Novella: Don't Attack the Moms

Managing Editor's Note: The following is a letter sent to Dr. Steven Novella, a neurologist at Yale University, from Dr. Jon Poling. (We've printed the letter with permission.) Dr. Novella is the founder of The New England Skeptical Society (meetings, 1st Tuesday of the month, on the lawn of the House of the Seven Gables, Salem, MA. BYOB (bring your own blinders.) and is a contributing editor to Quackwatch. Dr. Poling is a neurologist/PhD and the father of Miss Hannah Poling.

Dear Dr. Novella,

With regard to the science of Autism, I have no argument with the assertion that a single case does not prove causation of a generalized autism-vaccine link. What the case does illustrate though is a more subtle point that many physicians cannot or do not want to comprehend (ostensibly because vaccines are too important to even question). Autism is a heterogeneous disorder defined by behavioral criteria and having multiple causes. Epidemiological studies which have not found a link between autism and aspects of vaccination do not consider the concept of autism subgroups. Indeed, in a heterogeneous disorder like Autism, subgroups may indeed be ‘vaccine-injured’ but the effect is diluted out in the larger population (improperly powered study due to inability to calculate effect size with unknown susceptible subpopulation). I think former NIH Director, Dr. Bernadine Healey explained it best in that population epidemiology studies are not “granular” enough to rule-out a susceptible subgroup.

Furthermore, ‘science’ has not systematically studied the children who fell ill following vaccination to determine what the cause(s) for their adverse reaction was. It would follow that if you never tried to understand why a single child developed encephalopathy following vaccination—you wouldn’t have the first clue as to what aspects of vaccination you could alter which could increase the relative risk of that adverse event (whether it be thimerosal, live virus, or ‘too many’). Could the susceptibility be a mitochondrial genetic haplogroup similar to Chloramphenicol toxicity—sure it could! Why did a few Alzheimer’s patients die of fatal encephalitis following administration of the failed AN-1792 vaccine, but the majority had no ill effects (vaccine didn’t work though)?

Definition: Autism is a heterogeneous systemic disorder with primary neuropsychiatric manifestations due to complex genetic and gene-environmental interactions likely affecting synaptic plasticity early in childhood development. This new theory of Autism is rapidly replacing the ‘old guard’ dictum that Autism is a genetically predetermined developmental brain disorder of synaptic formation/pruning that is set in motion prenatally. By the ‘10 year rule of science,’ your time is about up!

Until the biological basis of ASD subgroups are better understood, further epidemiological and genetic studies regarding “Autism” causation will be relatively meaningless. We need good science to be able to address these complex issues which parallel nicely the emerging story of genetic and environmental influences in Parkinson’s disease. Perhaps some Parkinson’s researchers want to take a crack at Autism?

Thank-you Dr. Novella and his band of skeptics for continuing the debate.
