An Open Letter to Dr. Steven Novella Concerning His Positions on Vaccines and Autism and Dr. Novella's Reply
I am a parent of a 13 year old boy with Autistic Disorder. I also have a blog site on which I commented unfavorably on your response to the possibility that the IACC might recommend some vaccine autism research. I ask your response to a few questions if you have the time and are inclined to respond.
Respectfully,
Harold L Doherty
cc. Facing Autism In New Brunswick
Thanks for your thoughtful e-mail. I would be happy to address your questions.
Regarding further research - it is always possible, in the face of negative results, to call for still more research. And it is easy to make this seem like the default scientific position. ESP proponents, after a century of failed research, call for still more research, and accuses anyone who says further research is not worthwhile of being unscientific.
Also, to clarify my position, I am not categorically against further research into vaccines and autism. I think any such research is most likely to confirm the lack of a correlation. And if there is a susceptible sub-population, of course it would be good to know about it to make the vaccine program even safer. (But keep in mind - it is a common form of special pleading to argue that, when the effect you are looking for is absent, that is only exists is a subpopulation that existing data was not powerful enough to detect. This may be true, but it is just post-hoc speculation, and doesn't change the fact that the data is negative.)
My position is that ideological groups should not be dictating how scarce research funds are allocated. When we put money, people, and resources into chasing down an unlikely hypothesis those resources are not available for what might be more promising research. My position is that objective scientists, justifying their position with a careful analysis of the research, should decide how best to allocate scarce research funds. The anti-vax movement, however, is trying desperately to put their thumb on the scale - and that is what I oppose. They are trying to subvert autism activism to serve an anti-vaccine agenda - and they are hurting the autism community as a result, in my opinion.
I respect Healy and Gerberding, but I disagree with their approach in that they think more research will satisfy vaccine critics, but this is a naive position. The anti-vaccine movement has already demonstrated that they are impervious to facts and evidence, and spending time and money trying to placate them is a fool's errand. The CDC even went as far as to include them in designing a trial looking at vaccines and neurological disorders, and then only after the results came back negative, did they criticize the study.
You specifically mention an observational study comparing vaccinated and unvaccinated children - I do not oppose this. If it can be done with reasonable resources, there are scientists willing to carry out such a study and think it is worthwhile, and the results will be useful, then I fully support it and await the results. (And in fact I have never opposed such studies.) What I and others have written is that an experimental (not observation) comparison of vaccinated vs unvaccinated children is unethical, because it would randomize children to no get standard preventive care, and that directly violates human research ethical guidelines. Observational studies are fine, but they are never definitive, and they will not, in my opinion, change or end the debate. They will not move the anti-vaccinationists one bit
The increase in autism diagnoses has been studied from multiple angles - not just the expansion of the diagnosis.
You will find a summary of relevant research here: http://sciencebasedmedicine.
So far, every way it has been looked at the hypothesis that the increase in diagnosis of ASD is due to increased surveillance and expanded diagnosis has been confirmed. There is evidence of diagnostic substitution (as ASD numbers increase, the numbers of other similar diagnoses decrease). There is evidence that different age groups have the same prevalence of ASD (rather than increasing with younger age, as would result from a true increase in ASD). And if you apply the same diagnostic and surveillance methods to a cohort over time, you get the same ASD prevalence. The data is actually quite convincing that true autism rates are not significantly increasing (you cannot rule out a small real increase, or decrease for that matter, that the data is not powerful enough to detect) but that there has been expanded diagnosis with diagnostic substitution and increased surveillance.
I discuss this further here ( http://www.
The implications of this position to the alleged thimerosal link is complex, but supports a lack of correlation. What the data shows is that in various countries ASD diagnoses began to rise around the same time (as diagnostic patterns changed), in the early 1990s, and have continued to rise through today. Meanwhile, vaccine policies have varied considerably with regard to total thimerosal dose, with several countries, at different times, removing most thimerosal from vaccines. Every study looking at the data shows no correlation between the steadily increasing ASD diagnostic rates with the rising and falling thimerosal doses at different times in different countries. This is powerful evidence for a lack of correlation. As you likely know, toxicity is always about dose, and seeing a proper dose-response is essential to proving toxicity causation. What we have with thimerosal is an absolute lack of any dose-response, in many studies and sets of data.
Also, please keep in mind that the anti-vaccine movement used the increase in ASD in the 1990s as their original justification for the claim that thimerosal causes autism. They predicted that autism rates would decline after thimerosal was removed from the childhood vaccine schedule, and we agreed that if that happened we would need to rethink the possibility of a connection. Well, rates continued to rise without a blip, effectively putting the final nail in the coffin of the thimerosal hypothesis.
Regarding thimerosal and pregnancy, to the extent that this has already been studied (again, you can find references in the vaccine-and-autism link above) there has been no correlation. I do not oppose further research, however, if the CDC or others think it is warranted and feasible.
Thanks again for the interesting questions, and I hope this adequately clarifies my position.
Regards,
Steve Novella
PS - You can publish my response on your blog, and I will do likewise.

Autism Rising or Not? Mercury Disproved as Autism Cause or Not?
- "(10) AutismNewsBeat says:
“Will the media herd ever note that the same authorities who say that they can’t be sure that autism is really increasing today because of the 93-94 diagnostic definition changes state that that thimerosal was disproven as an autism trigger because autism increased after the alleged removal of thimerosal from vaccines in Denmark in 2002?”
Harold knows that there is a difference between an increase in “autism”, and an increase in “autism diagnoses”. There are no data to show one way or another that autism prevalence has increased much over the last two decades. But it is indisputable that autism diagnoses have grown considerably.
Perhaps AutismNewsBeat should tell Dr. Paul Offit to change the title to Chapter 6 of his novel "Autism's False Prophets" from "Mercury Falling" to "Mercury Falling, Autism Who Knows".
Which is it folks? Autism Rising or Not?. Thimerosal (Mercury) as Autism Cause Disproved or Not?

Autism Research, Treatment and Cure
Whether the Chicago Tribune likes it or not though parents will not quit on their children. While the health establishment and researchers dawdle in genetic past times parents of children with autism disorders will continue to try and help their children with the resources available whether the Tribune and health establishment like those resources or not.

Conor Returns to the Circle Place
Today though we were in the area anyway and with some gentle urging from Dad Conor revisited his old haunt and had a blast. He has grown at least half a foot since his last visit and his footing was a little wobbly to start but he got it back quickly and had lots of fun.
Dad was happy too.

Chicago Tribune Says Autism Treatment Uneccessary, Just Let It Be
And once again the Tribune makes no mention of the failure by public health authorities and researchers to seek all causes of autism or to attempt to find actual cures. Instead the Tribune simply ignores the real issues presented by autism disorders and sings "let them be, Lord them be" providing anecdotal evidence from Doctors that autistic children as they age will progress without intervention:
That is because, over time, children with autism do develop, said Dr. Max Wiznitzer, a pediatric neurologist and an autism expert at Rainbow Babies and Children's Hospital in Cleveland. They make leaps; some may plateau or regress, but they show improvement.
"Kids are at their worst in the second and third year of life," Wiznitzer said. "That is when they are not talking. That is when they are most into themselves."
But around age 3 the children often begin to talk, he said. "Over 3 to 5 years, you see an improvement in communication skills. ... By school age, they have language to get needs and requests met," Wiznitzer said.
This happens regardless of whether the child is undergoing alternative therapies, said Dr. Susan Levy, director of the Regional Autism Center at the Children's Hospital of Philadelphia. But parents may credit treatments for the gains."
And there we have it. In Chicago Tribune Autism World autism disorders do not require treatment. The solution to the challenges facing autistic children and their families can be found in the lyrics of John Lennon and Paul McCartney:
And when the broken hearted people
Living in the world agree,
There will be an answer, let it be.
For though they may be parted there is
Still a chance that they will see
There will be an answer, let it be.
Let it be, let it be. Yeah

Homeostasis Model of Autism Causation - Is Autism Triggered By Glutamite and Glycine Imbalance?
The model appears to be focused on a concept called "homeostasis" and views autism disorders as triggered by disruptions in the homeostatic relationship of several variables:
The second problem for the model is that the think tank members actually listened to, and received information from ...... parents of autistic children .... definitely a No No in the Vaccine Cult Era:
"According to The Center's founder, William McFaul, a retired business person and not a member of the scientific community, "Because of its universal applicability, our Life Sciences group has already used the model as a tool to identify highly probable causal paths for several illnesses and disease entities. Autism was one of most difficult illnesses The Center had attempted to analyze. If it hadn't been for so many parents insisting that vaccines were responsible for the condition, we might never have found the fact that the stabilizer in MMR and a few other vaccines is hydrolyzed gelatin; a substance that is approximately 21% glycine. It appears that, based on readily verifiable science, the use of that form of glycine triggers an imbalance between the amino acid neurotransmitters responsible for the absorption rate of certain classes of cells throughout the body. It is that wide-spread disruption that apparently results in the systemic problems that encompass the mind and the body characterized in today's 'classic' autism." He also added, "The use of our model indicates each of the disorders within Autism Spectrum Disorder (ASD) is attributable to different disruptions in homeostasis. We look forward to sharing our findings relative to each disorder with the scientific community."

Saskatchewan Still Canada's Autism Wasteland
In all fairness to Saskatchewan's political and public service elite they may not know much about autism disorders, or the importance of timely early intervention in helping autistic children live fuller, richer lives. Their failure to provide an autism intervention system with quality and integrity for autistic children across Saskatchwan appears to indicate a lack of any real understanding about autism disorders or the importance of early intervention in helping autistic children make real gains that will help them live fuller lives.
"We get warm bodies — with good intentions, but warm bodies — working with our children and they just fall farther behind.”
"NDP health critic Judy Junor said parents aren’t getting access to adequate treatment.
“It’s very time sensitive. These children can really progress so quickly with intensive therapy that meets their particular needs,” Junor said outside the assembly.
Parent Arden Fiala, whose daughter has Asperger syndrome, said she wants government to know there’s an urgency to the call for a strategy and for “individualized” funding in the interim that is not income-tested.
“The start of the action plan of the (Premier Brad) Wall government is just that — a start. It is not addressing the immediate and critical needs on the front lines and we’ve yet to see the benefits,” Fiala said."
