Why NIH Director Francis Collins Should Resign Immediately

SINCE THE RELEASE OF “CAUSES”, I’ve visited many states on tour sharing the balance of the science on the question of vaccines and autism.  One aspect of the weak “science” of correlation studies is that they often clean up the populations being studied using exclusionary criteria, excluding individuals who have indications of risk of autism.  The purveyors of these studies then, quite often, also “correct for” variables that may add to the risk of autism.  After carefully selecting populations not likely to develop autism, and correcting for risk factors of autism, the studies then conclude (without caveat) that “vaccines do not cause autism” in the general population.  This is called “overdrawing conclusions”.

Except those studies cannot possible conclude that, generally, vaccines do not cause autism.  First, correlation is insufficient evidence for causation.  That means that these studies do not represent a critical test of the hypothesis.  Second, after sanitizing the population of risk, and then performing statistical adjustments that remove autism risk variation from the study population, the population for which the result may be relevant is not a representative sample of the entire population.  It’s a subset.

If these studies looked at the interaction between vaccination and risk factors such as gestational age, mother’s age, mother’s income, birthweight (or a principle component aggregate variable composed of these variables), they may have found the association they originally found might have moved from the primary independent variables to the interaction term.  But these studies, instead, simply concluded (incorrectly) that vaccines have no effect, without reporting the significance of the interaction terms.

As I’ve traveled through California, Washington, Oregon, Michigan, Ohio, New York, Arizona, and Georgia, I have been careful to inform the audiences that ignoring the interaction term lead some to overdraw the conclusions of these studies as if they were relevant to the entire population, and that their execution places the studies outside of the purview of science.

I believe that Dr. Collins should resign his post from the NIH Directorship immediately.  My primary reasoning is that he does not understand how to draw inferences from MRI studies that have reported that children with autism have significant early structural differences in their brains compared to children without autism.   In his Director’s Blog article, Collins concludes:

“For those parents who still find themselves worrying about a possible connection between ASD and vaccines, despite study after study showing there’s no link, these new findings come as further reassurance. The biological foundations for ASD are present in the brains of children who will develop ASD-related behaviors from very early in life. The best way to keep all kids healthy and protected is to have them vaccinated on schedule.”

The fact that CDC was caught red-handed removing results showing positive association is not included in Collins’ blog article.  The fact that the IOM rejected 17/22 of the studies they were asked to examine on the question of vaccines and autism is not mentioned.  None of the studies that DO show association between vaccines and autism are mentioned by Collins in his blog article. But those are not the reasons why he should resign.

IOM quote

Collins might not know that the five studies left over (well, four, as two were repeated analysis of the same data) were woefully underpowered.  IOM should have known that. But I digress.

Collins should resign because these studies cannot possibly inform on the question of vaccines and autism.

These studies compared autistics and neurotypicals, or kids with older siblings who had autism, and did not include consideration of vaccines at all – neither in the children, nor in their moms when they were in the womb.

The appropriate study design to determine whether the changes can rule out, or rule in vaccines as contributing to autism risk would compare the rates of ASD, ADHD, and other neurodevelopmental disorders in

Autistics w/Early MRI Changes, Vaccinated

vs.

Autistics w/Early MRI Changes, Unvaccinated

This study design might indicate that those with early changes should avoid vaccines.

These studies are 100% moot on the role of vaccines. Failure to recognize this is a rookie mistake.  Collins has made up information out of thin air, and, as a result, he should no longer have any say over the research priorities of the NIH.

Aberrant brain connectivities is precisely what one would expect from vaccine-induced chronic microglial activation, one of the main causes of autism via vaccines.  Thus, finding changes in their brains when their moms may have been vaccinated, and when babies are given 250 micrograms of aluminum in the HepB shot on Day 1 or 2 of life is not surprising.

Here is Dr. Collins’ entire blog article, in case the NIH decides to “disappear” it from its site:

Autism Spectrum Disorder: Progress Toward Earlier Diagnosis
Posted on June 13, 2017 by Dr. Francis Collins

Research shows that the roots of autism spectrum disorder (ASD) generally start early—most likely in the womb. That’s one more reason, on top of a large number of epidemiological studies, why current claims about the role of vaccines in causing autism can’t be right. But how early is ASD detectable? It’s a critical question, since early intervention has been shown to help limit the effects of autism. The problem is there’s currently no reliable way to detect ASD until around 18–24 months, when the social deficits and repetitive behaviors associated with the condition begin to appear.

Several months ago, an NIH-funded team offered promising evidence that it may be possible to detect ASD in high-risk 1-year-olds by shifting attention from how kids act to how their brains have grown [1]. Now, new evidence from that same team suggests that neurological signs of ASD might be detectable even earlier.

That evidence comes from a study of children at high risk of ASD, who as babies underwent specialized brain scans while asleep to measure connectivity between different regions of the brain [2]. Using a sophisticated computer algorithm to analyze the scans, researchers could predict accurately which infants would receive a diagnosis of ASD 18 months later—and which would not. While the results need to be confirmed in larger groups of babies, these findings suggest that neuroimaging may be a valuable tool for early detection of ASD.

In the new study, researchers enrolled 59 babies who were 6 months old and had an older sibling diagnosed with ASD. That gave each a 20 percent chance of also developing the condition. The team, including Robert Emerson and Joseph Piven at the University of North Carolina at Chapel Hill and John Pruett at Washington University School of Medicine, St. Louis, then performed brain scans of each infant while napping, using functional magnetic resonance imaging (fMRI). That’s an imaging technique specially designed to measure neural activity.

With the scans in hand, the team created maps that, like a wiring diagram, showed the interconnections between 230 defined brain regions. All told, the researchers mapped out 26,335 brain connections spanning the entire brain.

Eighteen months later, the now-2 year-olds returned for a follow-up visit, where they underwent a series of cognitive, behavioral, and diagnostic assessments. Eleven of the 59 toddlers were determined to have ASD, or just over the predicted 20 percent.

The researchers wondered whether they could find clues as to those outcomes in the children’s brain connectivity maps. In an exciting sign of research progress, they could. Of the 26,335 functional brain connections measured at age 6 months, the researchers identified 974 that were related to the later development of ASD.

But were those differences enough to accurately predict which kids would develop ASD? To get the answer, the researchers used a special algorithm to allow a standard computer to process the original brain scans and “train” itself to distinguish between kids with ASD and those without. As part of this machine-learning process, the computer held out one baby’s scan at a time and then attempted to predict, based on the connectivity data for the other 58 children, whether or not that infant had ASD.

For 9 of the 11 babies who developed ASD, the computer predicted correctly. Based on data from just one brain scan at 6 months of age, that’s pretty extraordinary. Better yet, the computer never mistook a normally developing infant for one who developed ASD.

The researchers will now try to confirm their findings in larger groups of children. But they already have provided proof of principle that it’s possible to detect ASD long before children show the first visible signs of the condition. The findings could pave the way for developing more cost-effective mobile neuroimaging tools, which might be used in early ASD screening.

For those parents who still find themselves worrying about a possible connection between ASD and vaccines, despite study after study showing there’s no link, these new findings come as further reassurance. The biological foundations for ASD are present in the brains of children who will develop ASD-related behaviors from very early in life. The best way to keep all kids healthy and protected is to have them vaccinated on schedule.

One thought on “Why NIH Director Francis Collins Should Resign Immediately

  1. He can’t do the sort of basic arithmetic my fifth-graders could do in their sleep, either: eleven of fifty nine is 18.6%, under 20%, not over. How can people like Dr. Collins sleep at night, knowing the science they promote is phony? Surely he must know. A swamp-dweller for certain.
