Pediatrics have published a new paper, *Pervasive Developmental Disorders in Montreal, Quebec, Canada: Prevalence and Links With Immunizations* authored by Fombonne et al.
Pre-empting an NAA style ad hominem attack, the authors declare their conflicts early.
In the United Kingdom, Dr Fombonne has provided advice on the epidemiology and clinical aspects of autism to scientists advising parents, to vaccine manufacturers, and to several government committees between 1998 and 2001. Since June 2004, Dr Fombonne has been an expert witness for vaccine manufacturers in US thimerosal litigation. None of his research has ever been funded by the industry.
As they don’t agree with the paper this has caused the usual suspects, notably Safe Minds and FAIR Autism Media to highlight these aspects of the paper in an attempt to claim these invalidate the papers findings. Mark Blaxill of Safe Minds says that:
According to an analysis by SafeMinds, however, the study […] should be treated with skepticism, for a number of reasons.
Whilst David Ayoub states that:
“This is just another heavily biased study by an author with a long track record of financial ties to the drug industry, and whose previous views on the epidemiology of autism have been discredited,” wrote Ayoub
So, as far as the mercury militia are concerned, the following points are an issue.
1) Fombonne’s alleged financial ties to the drug industry. One assumes he is referring to Fombonne’s pre-stated offering of advice on the epidemiology and clinical aspects of autism and the fact that he’s an expert witness for vaccine manufacturers.
Let’s cut the shit here shall we? Richard Deth is a petitioners’ expert witness in major vaccine litigation. So are the Geier’s. So are various others. They have an equal ‘special interest’. Should we dismiss their papers out of hand? Either we allow *all* or allow *none*.
2) Fombonne’s previous views on the epidemiology of autism have been discredited.
Really? They have? By who? In what journal was this ‘discrediting’ published? Lets be clear here. Ayoub uses the word ‘discredited’. He didn’t say, ‘challenged’. He didn’t say ‘contraversial’ he said ‘discredited’.
David Ayoub by contrast, thinks that Rashid Buttar – a man who’s own patients think he’s a money grabbing quack – is an industry expert:
The 2 top chelation people in the world are Gary Gordon, MD, and Rashid Buttar, MD, he adds.
It’s my opinion that anyone who thinks Rashid Buttar is ‘top’ of anything autism related needs get his head back to reality pretty quickly.
3) Mark Blaxill at least takes a stab at something substantive. He questions the study methodology on two points. Firstly, he tries to insinuate that what might be true for Canada might not be for the US. Secondly he states that some of the study subjects may have received thiomersal from other vaccine sources than those noted in the study.
Fombonne et al write that:
The findings ruled out an association between pervasive developmental disorder and either high levels of ethylmercury exposure comparable with those experienced in the United States in the 1990s or 1- or 2-dose measles-mumps-rubella vaccinations.
So the word ‘comparable’ is used. Fombonne et al never attempt to state that it is a fact that what’s true for Canada is true for the US. However, its also true that there wouldn’t seem to be any good reason for _not_ thinking that. Why would the US and Canada be different? Surely thiomersal is thiomersal?
After that weak stab at something relevant, Blaxill retreats to Ayoub’s tactics of smear and spin.
Dr. Fombonne wrongfully claims that large-population studies in the United States, England and Denmark also disprove a link between mercury and autism, and he states that “there is no autism epidemic.”
The one mention of the word ‘Denmark’ in the entire paper is this one:
Our results are entirely consistent with cohort, case-control, and other ecological studies performed in Denmark and Sweden.
Fombonne et al never claim that these studies disprove anything. They merely note that consistency between those studies and their own. I can’t locate the use of the word ‘England’, ‘UK’, ‘united kingdom’ or ‘Britian’ anywhere in this paper so I fail to see why Blaxill mentions them.
Blaxill is guilty of intellectual dishonesty many times in his ‘rebuttal’. None more so than when he states that:
He conveniently ignores the vast body of scientific evidence that has shown that environmental factors such as mercury may have caused the increased number of autism diagnoses in the US and other countries.
Fombonne et al do not at any point discuss generalised ‘environmental factors such as mercury’. They discuss the key question regarding thiomersal and MMR. It raises questions about Blaxill’s integrity that he would try and switch the focus onto something he and his group explicitly have targeted to something much more general and which Fombonne et al does not address. This is a pattern becoming more and more apparent from key members of the mercury militia. As science continues to fail to support any causative link between thiomersal, MMR and autism, these groups are becoming much more generalised in their terminology. Expect to see more of this as 2006 draws to a close.
Blaxill also claims there is an increased number of autism diagnoses yet he fails to point to evidence for this. Fombonne’s own research on this point indicates a high but stable prevalence.
Blaxill continues:
Dr. Fombonne’s actions have not historically been in the best interest of families with autism—he has declared himself an expert witness on behalf of various pharmaceutical companies in thimerosal-related litigation.
By contrast, the Geier’s actions have not been in the interests of autistic peoples. And in fact this whole point about ‘best interests’ is childish in the extreme. The _only_ interest that science should adhere to is that of honest science. To suggest otherwise leaves a question mark over the objectives of Blaxill’s actions.
Several independent federal agencies and respected scientists and researchers have received federal funds to investigate the autism epidemic and the biological
plausibility of a link between mercury and ASDs.
Why is this even mentioned? Why not wait for them to be completed? Like this one already is.
Multiple studies have indicated that there is a connection between childhood vaccines containing thimerosal and the incidence of autism.
Blaxill (maybe purposefully) doesn’t mention _who_ might’ve conducted those studies, or where they were published. I’m guessing that he means the Geier’s but that recent revalations regarding their integrity and the quality of their work, made him think twice about saying their names for the record. Can’t say I blame him.
Skeptico, Orac and Autism Diva also comment on this study.
