I thank everyone for my warm welcome to the SBM community. Although vaccine myth is of particular interest to me, I promise that my posts wont all be vaccine related. There is, unfortunately, much to discuss. In fact I had a difficult time deciding which vaccine-related issue to write about for my inaugural post. In the end I came up with more of an opinion piece, but it’s an issue worth airing. Things in anti-vaccine land may be reaching a dangerous turning point.

Last week, two events took place in Washington that ought to inspire trepidation in the minds of all who value ethical, rational, science-based medicine and ethical, rational, biomedical research. One was the Senate Panel titled Integrative Care: A Pathway to a Healthier Nation, previously discussed by my fellow bloggers David Gorski, Peter Lipson, and Steve Novella, and also by the indefatigable Orac (here and here); the other was the “Summit on Integrative Medicine and the Health of the Public” convened by the Institute of Medicine (IOM) and paid for by the Bravewell Collaborative, previewed six weeks ago by fellow blogger Wally Sampson. This post will make a few additional comments about those meetings.
Senator Harkin and the Scientific Method
Thanks to Dr. Lipson, I didn’t have to listen to the Senate Panel video to find out that Senator Tom Harkin (D-Iowa) made this statement of disappointment regarding his own creation, the National Center for Complementary and Alternative Medicine (NCCAM):
One of the purposes of this center was to investigate and validate alternative approaches. Quite frankly, I must say publicly that it has fallen short. It think quite frankly that in this center and in the office previously before it, most of its focus has been on disproving things rather than seeking out and approving. (from last week’s hearings, time marker approx. 17:20)
Are scientists at the NIH really too afraid of Harkin to explain to him how science works? Apparently so. Otherwise Harkin might learn that his statement is more wrong-headed than it would be for one of us to complain that the Supreme Court ought to assume that a defendant is guilty until proven innocent, rather than the other way around. In scientific inquiry, for those who don’t know, good experimental design is always directed at disproving a hypothesis, even one that pleases its investigator. The rest of Harkin’s sentiment—“seeking out and approving”—is incoherent.
The Selling of ‘Integrative Medicine': Snyderman Trumps Weil
Spin doctors shilling for ‘integrative medicine,’ which the NCCAM defines as “combining treatments from conventional medicine and CAM,” appear to have now decided that subtler language is more likely to sell the product. We’ve previously seen an example offered by ‘integrative’ Mad Man Andrew Weil:
Just when I thought I was out… they pull me back in.
Michael Corleone in The Godfather, Part 3
I hadn’t planned on doing two vaccine posts with such a short interval between them, but all too often, as the they say in the weakest of the Godfather movies, I get pulled back in again. So, after noting last week that 2009 was shaping up–fortunately–to be a very bad year for antivaccinationists, I should have expected a counterattack from the antivaccine fringe. Indeed, the only thing that surprised me after the twin blows of the revelations about scientific fraud on the part of the originator of the claim that the MMR vaccine causes autism, Andrew Wakefield, and the resounding defeat of the first three test cases of the Autism Omnibus proceedings, was that it took longer than I had expected. True, a group had formed, proclaiming that “we support Dr. Andrew Wakefield.” Also true, the antivaccine activists at the Age of Autism have been working overtime to attack the Autism Omnibus as being hopelessly rigged. Indeed, our “old friend” Dr. Jay Gordon has even likened attempts to refute antivaccine pseudoscience to tobacco companies’ P.R. and astroturf campaigns back in the 1950s through 1980s to cast doubt on the strong scientific and epidemiological evidence showing that cigarettes cause lung cancer.
Unfortunately, the advertisement above was only the beginning. Generation Rescue managed to team up the chief progagandist for the antivaccine movement, David Kirby, along with Robert F. Kennedy, Jr., whom I have discussed before for his total support of the antivaccine movement. The question then becomes: Where would these two team up to spread their message against vaccines? Do you even have to ask?
Their twin articles appear on that repository of all things antivaccine, The Huffington Post, under the title Vaccine Court: Autism Debate Continues. As I will explain, these twin articles represent yet another example of what I have at times referred to as the “incredibly shrinking vaccine-autism hypothesis.”
I will begin this post with a bit of an explanation. Between one and two weeks ago, there appeared two momentous news about the manufactroversy regarding vaccines and autism. No doubt, many SBM readers were expecting that I, as the resident maven of this particular bit of pseudoscience, would have been here last week to give you, our readers, the skinny on all of this. Unfortunately, as some know, my wife’s mother died, coincidentally enough, on the 200th anniversary of Darwin’s birthday and a day when one of those two momentous bits of news was released to the public, which is why I used one of my handful of posts written and then held in reserve. I’m back now, though, and I don’t think it’s too late to comment on these bits of news because now that over a week has gone by what I’ve seen has led me to draw some conclusions that I might not have been able to do, had I done my usual bit and been first off the mark (at least among SBM bloggers) discussing the story.
2008: The Best of Years for the Antivaccine Movement
But first, let’s take a look at last year. In 2008, Jenny McCarthy was the new and fresh celebrity face of the movement that believes that autism and all manner of other neurodevelopmental disorders are caused by vaccines and that the government and big pharma are suppressing The Truth. She had emerged in the fall of 2007 after having tried to erase from the Internet her previous involvement in the “Indigo Child” movement in preparation for becoming an “autism advocate” who could write a book that could land her on Oprah’s show. Thanks to her and, perhaps even more so to the star power of her boyfriend Jim Carrey, who is just as wrong about vaccines and medicine as Jenny is, the antivaccine movement came roaring into prominence in a way that it had never managed to pull off before. After all, let’s face it, a former Playboy Playmate of the Year and a famous comedian are far more “interesting” public figures for various media outlets to interview than previous celebrities who spearheaded the vaccine manufactroversy, such as Robert F. Kennedy, Jr. or Don Imus and his wife Deirdre.
Indeed, Jenny’s combination of good looks and utter obnoxiousness led to her showing up all over the media in 2008. For example, on April 1 (appropriately enough), she appeared on Larry King Live! and shouted down physicians who had the temerity to tell her that her Google University knowledge was just plain wrong. The pinnacle of her influence came during the summer, when, having now supplanted J.B. Handley as the public face of the antivaccine group Generation Rescue and transforming GR into “Jenny McCarthy’s autism charity,” she led the “Green Our Vaccines” rally in Washington, DC. True, at most there were several hundred people there, but it got wide news attention, and Jenny was all over the news. She rapidly followed it up by releasing a second book Mother Warriors: A Nation of Parents Healing Autism Against All Odds and appearing on The Oprah Winfrey Show yet again.
Last week the Times of London revealed inside information from the General Medical Council (UK, responsible for physician licensing) of an ongoing investigation of Dr. Andrew Wakefield and from its own investigation. This revelation recalled other instances of fakery from reports of sectarian medicine (“CAM”) successes. The Medical Council information contained evidence that the data from the now famous Wakefield cases used to claim an association of the MMR vaccine with childhood autism and inflammatory bowel disease were misinterpreted, altered, and to some extent, faked. The report and history were reviewed by David Gorski last week. In eight of twelve cases, the dates of autism onset were “rearranged” to fit the needed time association, and many small bowel biopsies were “reinterpreted” to show inflammation.
The Wakefield claims were long suspected by reputable medical scientists and skeptics as being erroneous or fraudulent. Note: the Council hearings are still in progress, and the Times report is subject to legal complaint. The original details can also be seen in the Times articles.
This expose’ adds to a growing list of reports with erroneous and faked information in medical journals used either for economic reward, undeserved fame, or to promote ideological claims for medical sects and cults. Although history of erroneous or false claims goes back hundreds of years, the altering or synthesizing of data passing the recently conceived peer review system is new, illuminating defects in the journal peer review and editing system.
If journals were invented in the 18th century, and operated like journals of today, Mesmer’s demonstrations might have been published, and the Ben Franklin and Antoine Lavoisier and French Academy’s disproof might have been rejected. (Laughter here.) But journals continue to make major goofs in publishing implausible results despite the popularity of a famous specialty journal for that purpose.
Examples vary from acceptance of language manipulation – “alternative,” “healing,” “integrative,” etc., to the fakery of recent papers showing effects of prayer. The two famous studies of prayer in the cardiac care unit ranged from the unadmitted breaking of the blind in the Bird study (So Med J 1988; 81:826-826) to unadmitted imbalances of subject and control groups (Harris, Arch Int Med 1999;159:2273-2278.) And from those to the likely fakery of the distant prayer study of in vitro fertilization (Cha, Wirth, Lobo; J Reprod Med 2001:46;781-786) in which three separate prayer groups on two continents improved pregnancy rates in a group of women on a third continent by an implausible 100 percent. In all of these cases, the papers passed peer or editorial review despite the methodological defects that were picked up by us skeptics (K. Atwood, K.Courcey [an RN] B. Flamm, and others.)
Adding insult to the above, Annals of Internal Medicine published a systematic review of intercessory prayer (Astin et al, Ann Int Med, 2000;132: 903-910) containing not only the Bird and Harris studies counted as positive, but also the Targ study on brain tumors, found by reporter Po Bronson to have had its end point altered by the authors when the primary one showed no effect.
Pity poor Andrew Wakefield.
Actually, on second thought, Wakefield deserves no pity at all. After all, he is the man who almost single-handedly launched the scare over the MMR vaccine in Britain when he published his infamous Lancet paper in 1998 in which he claimed to have linked the MMR vaccine to regressive autism and inflammation of the colon, a study that was followed up four years later with a paper that claimed to have found the strain of attenuated measles virus in the MMR in the colons of autistic children by polymerase chain reaction (PCR). It would be one thing if these studies were sound science. If that were the case, then Wakefield’s work would have been very important and would have correctly cast doubt on the safety of the MMR. Unfortunately, they were not, and, indeed, most of the authors of the 1998 Lancet paper later withdrew their names from it.
Over the next decade, aided and abetted by useful idiots in the media, by British newspapers and other media that sensationalized the story, and the antivaccine movement, which hailed Wakefield as a hero, Wakefield managed to drive MMR vaccination rates in the U.K. below the level of herd immunity, from 93% to 75% (and as low as 50% in some parts of London). As a result Wakefield has been frequently sarcastically “thanked” for his leadership role in bringing the measles back to the U.K. to the point where, fourteen years after measles had been declared under control in the U.K., it was in 2008 declared endemic again.
Since when did an apologist for the antivaccination movement, Dr. Jay Gordon, become an “expert” in vaccine law?
I am an alumnus of the University of Michigan twice over. I completed a B.S. in Chemistry with Honors there in 1984 and then I stayed on to do obtain my M.D. in 1988. I look back very fondly on those eight years spent in Ann Arbor, as several of my longtime friendships were forged or solidified during those years. Consequently, I still care about the place. Indeed, I even once tried to see if I could get a position in the Department of Surgery there a few years back, but unfortunately the “fit” just wasn’t there at the time. That’s why it distresses me when I see my alma mater suffer from a self-inflicted wound, almost as much as the plight of the Michigan Wolverines bothers me, given that never before in my life (at least not since I was old enough to pay attention), have the Wolverines sucked so badly and so hard. Given that level of football futility, though, I consider it even more important that my alma mater not provide any more ammunition to those who would enjoy making fun of it. It doesn’t matter to me that I never went to law school at Michigan; it’s all part of the same campus to me.
This time, the embarrassment comes in the form of an article in the Michigan Law Review by a person who has previously been a subject of posts by both Dr. Novella and me. I’m referring to Dr. Jay Gordon, whom we have both–correctly, I believe–labeled as being, if not fully anti-vaccine, at least a prominent and major apologist for the anti-vaccine movement. Unfortunately, because he is the pediatrician taking care of Jenny McCarthy’s son Evan, he has gained even greater prominence in the antivaccine movement than ever, to the point where he gave a speech last summer to the antivaccine “Green Our Vaccines” march on Washington and where he is regularly called up by TV producers to give a false “balance” whenever a discussion of vaccines and/or autism comes up. He also wrote the foreword to Jenny McCarthy’s latest paean to autism quackery and attack on vaccines as the cause of autism in which he blithely repeated some of the worst distortions of the antivaccine movement. Unfortunately, Dr. Gordon lacks the intestinal fortitude to stop the piteous denials any time he is called out for his parroting of antivaccine pseudsocience and to embrace his inner antivaccinationist. Then, at least, we wouldn’t be treated to the spectacle of his simultaneously claiming he is “pro-safe vaccine, not anti-vaccine” while at the same time saying he “doesn’t give a lot of vaccines” and admitting that parents have actually had to persuade him to vaccinate “reluctantly.”
So what was the topic of the Michigan Law Review article that Dr. Gordon was apparently asked to pen? It’s actually an interesting question from a legal, political and civil rights standpoint, specifically: Whether or not parents should be held legally liable for refusing to vaccinate their children. Not surprisingly, Dr. Gordon took the “no” position. Unfortunately, as we’ve come to expect of Dr. Gordon, he uses a number of highly dubious arguments. However, more interesting to me, having had a nearly four year history sparring online with him off and on, was the seemingly “kinder and gentler” antivaccine stance that he took in this article.
But first, let’s take a look at the debate. The symposium published in First Impressions (the online companion to the Michigan Law Review) was entitled Liability for Exercising Personal Belief Exemptions from Vaccination, and it contained the following articles:
- Choices Should Have Consequences: Failure to Vaccinate, Harm to Others, and Civil Liability by Douglas S. Diekema.
- Parents Should Not be Legally Liable for Refusing to Vaccinate their Children by Dr. Jay Gordon.
- Unintended Consequences: The Primacy of Public Trust in Vaccination by Jason L. Schwartz.
- Challenging Personal Belief Immunization Exemptions: Considering Legal Responses by Alexandra Stewart.
- Gambling with the Health of Others by Stephen P. Teret and John S. Vernick.
- The Problem of Vaccination Noncompliance: Public Health Goals and the Limitations of Tort Law by Daniel B. Rubin and Sophie Kasimow
There were a number of fascinating issues raised here. Although it’s obvious that universal vaccination is a public health policy good, given that the higher percentage of vaccinated children, the greater the herd immunity, there is always the nagging question of how far the state should go to mandate vaccination in a free society; i.e., how much coercion is acceptable to bring about maximal levels of vaccination? In other words, what is the proper balance between the needs of society as a whole and the rights of the individual? The next interesting legal and moral question is whether parents who refuse to vaccinate should be held liable for injuries to other children if their unvaccinated child passes on an infectious disease. Personally, I tend to believe that it is entirely reasonable to require vaccination as a precondition for school or day care and that exemptions should be primarily medical in nature. I grudgingly allow that the freedom of religion guaranteed in the First Amendment probably requires religious exemptions (although I do not understand why religion should be given such a privileged place in society that it can endanger public health), I am far less convinced that philosophical exemptions should be mandated. I realize many may disagree with this position, but I would hope that our disagreements would be based on (1) the best science regarding the benefits and risks of vaccination and (2) honest beliefs regarding the proper balance between public health concerns and individual liberty. Clearly, this is an area of debate. I also tend to believe that if parents refuse to vaccinate their child and that child passes an infectious disease to another child, then those parents should be potentially legally liable. Indeed, Douglas Diekema argues this position very well.
Unfortunately, Dr. Gordon does not meet at least condition #1 above. He does not base his arguments on the best science.
The more recent issue of the Journal Pediatrics contains two article providing further evidence for the safety of vaccines and is published amid news reports of recent outbreaks of vaccine-preventable diseases in those who chose not to vaccinate over unwarranted fears. This highlights the need to continue our PR battle against the antivaccinationist movement that seeks to spread pseudoscientific fears about vaccine safety.
Haemophilus influenza type B (Hib) is a bacteria that can cause meningitis, pneumonia, and epiglotitis in young children – all serious illnesses. A Hib vaccine was introduced in 1992 followed by a significant decrease in the number of Hib infections. Last year in Minnesota, however, there were five cases of Hib meningitis, including a 7-month old infant who died. This is a significant spike above the rate we have seen since the Hib vaccine, and occuring in a cluster. Three of the five children who were affected did not have the Hib vaccine by their parent’s choice.
It is without controversy that the number of autism diagnoses being made is on the rise. In 1991 there were about 6 cases per 10,000 births, and in 2001 there were about 42. This number continues to rise at about the same rate.
The cause of this rise, however, is very controversial. There are basically two schools of thought: 1 – that true autism rates are on the rise, and 2 – that the measured rise is an artifact of increased surveillance and a broadening of the definition. I wrote previously about this very controversy, in which I concluded that the expanded diagnosis hypothesis is much better supported by the evidence.
Now, a new study published last week in the journal Epidemiology is being presented by proponents of the epidemic hypothesis as support for their view. A closer look, however, reveals that this study does not support the epidemic hypothesis and adds little to the overall literature on this question.
Without question, vaccination has been one of the most important interventions in disease prevention that has ever been developed. In spite of the demonstrable, and ongoing, success of vaccination, a small, but vocal, anti-vaccination movement has developed in human medicine, occasionally buttressed by horrifying instances of adverse reactions, as well as the occasional publications in scientific journals (vis, the Wakefield debacle). Vaccine development continues, and human health continues to benefit, as new vaccines are developed and tested prior to release.
In veterinary medicine, vaccination has also proven to be a boon for animal health. Diseases such as canine parvovirus and canine distemper, feline leukemia, or equine tetanus, have been greatly reduced – in some cases, nearly eliminated – by vaccination. And, as in human medicine, a small, but vocal, anti-vaccination movement has developed, regaling fearful listeners with tales of acute harm, or chronic, low-grade disease (sometimes termed “vaccinosis”).
