Yet another nail in the coffin of the myth that the MMR vaccine causes autism

Arguably, the genesis of the most recent iteration of the anti-vaccine movement dates back to 1998, when a remarkably incompetent researcher named Andrew Wakefield published a trial lawyer-funded “study” in the Lancet that purported to find a link between “autistic enterocolitis” and measles vaccination with the measles-mumps-rubella (MMR) trivalent vaccine. In the wake of that publication was born a scare over the MMR that persists to this day, 11 years later. Although peer reviewers forced the actual contents of the paper to be more circumspect, in the press Wakefield promoted the idea that the MMR vaccine either predisposes, causes, or triggers autistic regressions. Even though over the next several years, investigations by investigative journalist Brian Deer revealed that not only was Wakefield’s research funded by trial lawyers looking to sue vaccine manufacturers for “vaccine injury” when he did his research (for which he is now being charged by the U.K.’s General Medical Council with scientific misconduct), but during the Autism Omnibus trial testimony by a world-renowed expert in PCR technology showed that he was incompetent. Even worse for Wakefield, in February 2009 Brian Deer published a news expose based on strong evidence that Wakefield may very well have falsified data for his Lancet paper.

None of this mattered. Andrew Wakefield still enjoys a cult of personality among the anti-vaccine crowd that no revelation seems able to dislodge, even the revelation that at the time he was both in the pay of trial lawyers and working on his study, Andrew Wakefield was also applying for a patent for a rival measles vaccine. Indeed, the anti-vaccine propaganda blog Age of Autism bestowed upon him last year its “Galileo Award” as the “persecuted” scientist supposedly fighting for truth, justice, and anti-vaccinationism against the pharma-funded or brainwashed minions of the “Church of the Immaculate Vaccination.” In the meantime, MMR uptake rates in the U.K. have plummeted over the last decade, far below the level needed for herd immunity, to the point where, last year the Health Protection Agency declared measles to be once again endemic in the U.K., 14 years after the local transmission of measles had been halted.

Since Wakefield’s study was released, a number of studies have shown that there is no epidemiologically detectable link between vaccination with MMR and autism, including one by a researcher who once appeared to be a believer in the idea that vaccines are somehow linked with autism, Mady Hornig. Hornig actually tried very hard to replicate Wakefield’s 1998 Lancet study, only this time with more children, and she found no link between MMR and autism using methodology similar to Wakefield’s. None of these studies has had any effect on the anti-vaccine movement, except to motivate them to circle the wagons even more, as J.B. Handley of Generation Rescue did when he launched a website called Fourteen Studies, whose purposes are to launch fallacious and pseudoscientific attacks on studies failing to find a link between vaccines and autism (often involving accusations of being a “pharma shill”), to promote the lousy science that gives the appearance of supporting the hypothesis that there is a link between the MMR vaccine and autism, and then slime anyone who points out how deceptive their attacks were.

Now, yet another study has been released studying whether there is a link between MMR vaccination and autism. Yet another study has failed to find a link between MMR vaccination and autism. Yet another study is all set to be attacked by Generation Rescue and the anti-vaccine movement. The sad and sordid history of reactions of the anti-vaccine movement to studies that do not support its belief in the unsinkable rubber duck of a myth that vaccines cause autism. This study was published online in The Pediatric Infectious Disease Journal by a group from Department of Epidemiology and Preventive Medicine, Jagiellonian University, Collegium Medicum, Krakow, Poland (a Polish group, my people!) and entitled Lack of Association Between Measles-Mumps-Rubella Vaccination and Autism in Children: A Case-Control Study. It’s yet another nail in the coffin of the myth that the MMR causes or contributes to autism. Indeed, this study not only shows that MMR vaccination is not associated with autism but that it may even be protective against autism. True, for reasons I will discuss shortly, I doubt that that latter interpretation is true, but there’s no doubt that this study is powerful evidence against the view that there is an association between MMR and autism. Unfortunately, I fear that all the nails in my local Home Depot would not be enough to keep the zombie of this pseudoscience from rising from its grave yet again.

The autism “biomed” movement: Uncontrolled and unethical experimentation on autistic children

Ever since I first discovered the anti-vaccine movement, first on Usenet, specifically on a Usenet newsgroup devoted to discussing alternative medicine (misc.health.alternative, or m.h.a. for short) and then later on web and on blogs, there have been two things that have horrified me. First, there are the claims that children suffer all sorts of harm from vaccines, be it being made autistic (with the attendant “autism epidemic” caused by vaccines), suffering neurological damage, immune system damage, and all manner of other adverse consequences. There is no good evidence for these claims (although, as has been documented right here on this very blog time and time again, anti-vaccine activists will trot out all manner of awful studies to support their contentions), but that doesn’t keep useful celebrity idiots like Jenny McCarthy, Jim Carrey, Don Imus, or Bill Maher from repeating the same myths over and over again. Worse, the permeation of society with these myths about vaccines has led to declining vaccination rates and the resurgence of potentially deadly vaccine-preventable diseases. It began first in the U.K. in the wake of Andrew Wakefield’s trial lawyer-funded, incompetent, and possibly fraudulent “research,” and has spread to the U.S., thanks to Jenny McCarthy and her ilk, who won’t take responsibility for their words and actions.

Even worse, the myth that vaccines cause autism has led to ideas. Dangerous ideas, and not because they “challenge” medical orthodoxy. These ideas are dangerous because they have direct consequences for children with autism. These consequences take the form of subjecting children to unscientific treatments that are ineffective at best and harmful at worst, sometimes even life-threatening. Indeed, I have written about case histories in which children were subjected to injections of “stem cells” into their cerebrospinal fluid by lumbar puncture and various other “treatments,” as well as chemical castration in combination with chelation therapy. That latter bit of quackery is something I wrote about years ago, but that the mainstream press only just noticed earlier this year. Better late than never, I guess. Even better than that, though, the same reporting team at the Chicago Tribune that reported on Mark and David Geier’s advocacy of Lupron to treat autistic children back in May. Sadly, the result of that story does not appear to have been actions by the State of Maryland to take away Dr. Mark Geier’s medical license or to go after his son David for practicing without a license. Neither does it appear to have resulted in insurance companies going after them for prescribing an expensive drug for an indication for which it is not appropriate. What it does appear to have done, however, is to inspire the same journalist, Trine Tsouderos, along with another journalist from the Chicago Tribune, Patricia Callahan, to pursue an even bigger target that Mark and David Geier, namely the entire “autism biomed movement,” which is for the most part rank quackery, in the following articles:

This is another rare case of excellent reporting on this issue, and I hope that this report (another installment of which was published early this morning after I had written this post) will grab the attention of more reporters and news outlets, leading to shining a light on the dark underbelly of the autism biomed movement.

Monkey business in autism research, part II

Over the last couple of months, I’ve noticed something about the anti-vaccine movement. Specifically, I’ve noticed that the mavens of pseudoscience that make up the movement seem to have turned their sights with a vengeance on the Hepatitis B vaccine. The reason for this new tactic, I believe, is fairly obvious. The fact that the Hep B vaccine is administered shortly after birth seems somehow to enrage the anti-vaccine movement more than just about any other vaccine. Moreover, given that, aside from maternal-child transmission when the mother is infected, hepatitis B is usually only contracted through either bloodborne contact (the sharing of needles, the administration of contaminated blood) or sexual activity, it’s very easy for anti-vaccinationists to make a superficially plausible-sounding argument that it’s not a necessary vaccine, even though there are reasonable rationales for giving it to infants. The image of sticking a needle into a newborn infant trumps that, though, at least for the anti-vaccine movement. Another possibility, suggested by Steve Novella just yesterday, is that, with the collapse under a overwhelmingly huge pile of evidence of the idea that the mercury-containing preservative thimerosal that used to be used in childhood vaccines until 2001, caused an “epidemic” of autism and the failure of the “too many too soon” slogan to convince anyone who is not already an anti-vaccinationist, the movement needed a new bogeyman to blame for autism. The hepatitis B vaccine, which was added to the pediatric vaccination schedule in the 1990s, around the right time to confuse correlation with causation when it comes to the increase in autism diagnoses (just like thimerosal) was a perfect next target, given that it’s administered shortly after birth.

Indeed, just the other day, the anti-vaccine crank groups the National Vaccine Information Center (NVIC), Talk About Curing Autism (TACA), and the anti-vaccine crank blog Age of Autism posted a call for the elimination of hepatitis B vaccination for newborns:

Washington, DC – National Vaccine Information Center and Talk About Curing Autism are calling on President Obama to order the immediate suspension of the Centers for Disease Control and Prevention recommendation of the birth dose of the Hepatitis B vaccine after two recent studies linking the Hepatitis B vaccine to functional brain damage in U.S. male newborns and infant primates.  In a related development today, the United States Department of Health and Human Services, including the Health Resources and Services Administration and Centers for Disease Control and Prevention,  announced that 1 in every 91 children are now diagnosed with an autism spectrum disorder as reported in the November 2009 issue of Pediatrics. Previous data released by the CDC indicated a prevalence of 1 in every 150 children affected by the disorder.

Note how AoA not-so-subtly interposed the latest information about autism prevalence with its call to eliminate the birth dose of the hepatitis B vaccine. Very clever. By doing so, it linked the two in readers’ minds, as if one had something to do with the other. There’s no good scientific evidence that the hepatitis B vaccine has anything to do with the “autism epidemic.” Meanwhile, David Kirby is up to his usual nonsense, and the resident anti-vaccine propagandist at CBS News, Sharyl Attkisson, who has been known to feed Age of Autism information on at least one occasion in the past, served up this credulous, noncritical interview with Andrew Wakefield:

The quantity of misinformation in that single six minute video is far beyond the scope of this article. Were I to start dissecting it, I would not have time to do what the purpose of this article was intended to do: To deal with the study Wakefield is hawking. That’s why I leave the dissection of this pièce de résistance of disingenuousness and misinformation as an exercise for SBM readers–after reading the rest of this post, of course. Trust me, it will help you.

At the heart of this latest propaganda onslaught by the anti-vaccine movement are two studies, one a restrospective study in humans and the other a study in monkeys, both of which the anti-vaccine movement is promoting as slam dunk evidence that the hepatitis B vaccine is causing all sorts of horrific problems. Taking both of them on in one post is too much, even for my logorrheic tendencies. So I’ll deal first with Wakefield’s monkey study and then, either later this week or sometime next week, hopefully discuss the human study.

The price of anti-vaccine fanaticism: Case histories

One of the major themes of SBM has been to combat one flavor of anti-SBM movement that believes, despite all the evidence otherwise, that vaccines cause autism and that autism can be reversed with all sorts of “biomedical” quackery. Many (but by no means all) of these so-called “biomedical” treatments are based on the false view that vaccines somehow caused autism. I and my fellow SBM bloggers have expended huge quantities of verbiage refuting the pseudoscience, misinformation, and outright lies regularly spread by various anti-vaccine groups and two celebrities in particular, namely Jenny McCarthy and her boyfriend Jim Carrey. Most of the time, we discuss these issues in terms of the harm to public health that is done by falling vaccination rates due to the fear engendered by the message of the anti-vaccine movement and the threat of the return of vaccine-preventable diseases that once wreaked havoc among children.

There is another price, however. There is a price that is paid by autistic children themselves and their parents. It is a price paid in money and lost time. It is a price paid in being subjected to treatments that are highly implausible from a scientific standpoint and for which there is no good scientific evidence. It is a price that can result in bankruptcy, suffering, and, yes, even death.

It is a price, I think, that is best demonstrated through a few case studies. This is a situation when anecdotes have their use.

The perils and pitfalls of doing a “vaccinated versus unvaccinated” study

The anti-vaccine movement is nothing if not plastic. It “evolves” very rapidly in response to selective pressures applied to it in the form of science refuting its key beliefs. For instance, when multiple studies looking at the MMR vaccine and autism failed to confirm the myth that the MMR causes autism or “autistic enterocolitis,” most recently late last year, it was not a problem to the anti-vaccine movement. Neither was it a major problem to the movement when multiple studies similarly failed to find a link between mercury in the preservative thimerosal that used to be in most childhood vaccines and is no more (except the flu vaccine) and autism. No problem! Andrew Wakefield is alleged, based on strong evidence, to have falsified his data alleging a link between the MMR vaccine and “autistic enterocolitis”? Fuggedabouddit! The anti-vaccine movement simply pivoted neatly, de-emphasized points that the evidence was so clearly against that even they couldn’t spin it to a positive anymore, and found new bogeymen. These days, it’s the “toxins” (such as formaldehyde and the latest antivax bogeyman, squalene), and “too many too soon” (a gambit given seeming respectability by Dr. Bob Sears and Dr. Jay Gordon, apologists for and supplicants to the anti-vaccine movement both.

However, there is one trait of the anti-vaccine movement that, however its camouflaging plumage may evolve, never, ever changes. It is as immutable as believers say that God is. That trait is that, whatever other claims, the anti-vaccine movement makes, at its core it is always about the vaccines. Always. No matter how often science fails to find a link between vaccines and autism or vaccines and whatever other horreur du jour the anti-vaccine movement tries to pin on vaccines, no matter how many studies do not support the viewpoint that vaccines cause autism, no matter how much the anti-vaccine movement tries to deny and obfuscate by saying that it is not “anti-vaccine” but rather “pro-safe vaccine,” at its core the anti-vaccine movement is about fear and loathing of vaccines. Always. When inconvenient science doesn’t support their views, anti-vaccine activists either ignore the science, distort the science, or launch ad hominems against the people doing the science or citing the science. And, as I said before, the claims of the anti-vaccine movement evolve. Never again will the anti-vaccine movement make the horrific mistake of yoking itself to a hypothesis that is as easily testable as the hypothesis that mercury in vaccines causes autism. The claim that mercury in vaccines causes autism predicted that, if thimerosal were removed from vaccines or reduced to pre-”epidemic levels” of the early 1990s, then autism rates should plummet. Thimerosal was removed from nearly all childhood vaccines (the sole exception being some flu vaccines), reducing infant mercury exposure from vaccines to levels not seen since the 1980s; yet autism rates continue to rise. This is about as resounding a refutation of the hypothesis that mercury in vaccines is a major cause or contributor to autism that even the anti-vaccine movement has backed away from the pure claim, which has now evolved to unnamed “environmental toxins,” either in concert with mercury or with other nasty things, as being the Real One True Cause of Autism.

It’s evolution in action. These new claims are much “fitter” because they are much harder to falsify through scientific research, epidemiology, and clinical trials.
