We’ve written a lot about anti-vaccine zealotry on this blog, as Steve and I take a particular interest in this particular form of dangerous pseudoscience for a number of reasons. One reason, of course, is that the activities of antivaccine groups like Generation Rescue and its spokesmodel since 2007 (Jenny McCarthy, a frequent topic on this blog) have started to frighten parents about vaccines enough that vaccination rates are falling well below that required for herd immunity in some parts of the country. Indeed, McCarthy, at the behest of her handlers in Generation Rescue, serves up a regular “toxic” brew of misinformation and nonsense about vaccines, most recently in a video that was the subject of a post by Val Jones about her unbelievably pseudoscience-laden blather. Truly, it has to be seen to be believed. Meanwhile, Generation Rescue has sent McCarthy on a media propaganda tour for her latest antivaccine pro-quackery book and set up a misinformation-laden propaganda site called Fourteen Studies (blogged about by Steve Novella, Mark Crislip, and, of course, yours truly) in which they attack well-designed studies that have failed to confirm their pet idea that somehow, some way, vaccines must be the cause of autism. And, when their pseudoscience is criticized, the antivaccine movement has a tendency to launch vicious ad hominem attacks, as they recently did against Steve Novella and have done multiple times in the past against me.
However, there is one other consequence of the antivaccine movement, however, and it is at least as important as the public health implications of the potential dimunition of herd immunity caused by the fear mongering of groups like Generation Rescue. That consequence is the cottage industry of “biomedical” treatments to which desperate parents subject their children. Gluten-free diets, chelation therapy (which has caused deaths), hyperbaric oxygen chambers (a recent story described a child getting severely burned when one of these caught fire), autistic children have been subjected to it all. But of all the biomedical woo to which autistic children have been subjected, one form of woo stands out as being particularly heinous. Indeed, I agree with our fearless leader Steve in characterizing it as an “atrocity.”
I’m referring to Mark and David Geier’s favored “treatment” for autistic children, namely a drug called Lupron. (more…)
I’ve been fairly quiet about Jenny McCarthy’s campaign against childhood vaccinations, partly because Dr. David Gorski has covered the issue so thoroughly already, and partly because of my “do not engage” policy relating to the deeply irrational (i.e. there’s no winning an argument with “crazy.”) But this week I was filled with a renewed sense of urgency regarding the anti-vaccinationist movement for two reasons: 1) I received a personal email from a woman who is being treated with hostility by her peers for her pro-science views on vaccines and 2) a friend forwarded me a video of Jenny McCarthy speaking directly to moms, instructing them to avoid vaccinating their kids or giving them milk or wheat because of their supposed marijuana-like addictive properties.

My inaugural post was about vaccines, and I promised that I wouldn’t write exclusively on this topic. But something rotten is brewing in the state of Georgia and this story is just too important to ignore.
The first successful challenge to the National Childhood Vaccine Injury Compensation Act (NCVICA) has taken place in Georgia, and we all should be just a little bit worried. In Ferrari v. American Home Products Corp., the plaintiffs, Marcello and Carolyn Ferrari of Atlanta, have sued American Home Products Corp. (otherwise known as Wyeth) and the co-defendant GlaxoSmithKline, claiming that the vaccine preservative thimerosal led to their son’s autism. The consequences of this ruling could effect the health of the entire nation. To understand why, we need to delve a bit into what the NCVICA is exactly, and why it was created in the first place. (more…)
I realize that our fearless leader Steve Novella has already written about this topic twice. He has, as usual, done a bang-up job of describing how Arianna Huffington’s political news blog has become a haven for quackery, even going so far as to entitle his followup post The Huffington Post’s War on Science. And he’s absolutely right. The Huffington Posthas waged a war on science, at least a war on science-based medicine, ever since its inception, a mere two weeks after which it was first noticed that anti-vaccine lunacy ruled the roost there. Because I’ve had experience with this topic since 2005, I thought I’d try to put some perspective on the issue, in order to show you just how pervasive pseudoscience has been (and for how long) at the blog whose name is often abbreviated as “HuffPo.” (more…)
Arguably the most difficult aspect of science-based medicine is where the rubber hits the road, so to speak. That’s where scientists and physicians take the results of preclinical studies performed in vitro in biochemical assays and cell culture models and in vivo in animal models to humans. There are numerous reasons for this, not the least of which that preclinical models, contrary to what animal rights activists would like you to believe, do not predict human responses to new therapeutic agents as much as we would like. However, the single biggest reason that we cannot answer questions in human studies as easily as we can in cell culture and animal studies is ethics. Of course, answering questions using cell culture and animal studies is not “easy,” either, but performing studies using human beings as subjects is an order of magnitude (at least) more difficult because the potential to cause harm exists, and if harm is caused by the experimental treatment under study, that harm will be done to human beings, rather than cells in a dish or mice bred for research.
The “gold standard” type of study that we do to test the efficacy of a new drug is known as the randomized, placebo-controlled, double-blinded study, often abbreviated RCT. Indeed, this remains the gold standard and is accorded the highest level of “power” in the framework of evidence-based medicine. Of course, as we have argued time and time again, using the RCT to test therapies that are incredibly implausible on a strictly scientific basis (homeopathy or reiki, for instance) inevitably leads to numerous “false positives” in which the therapy appears to produce results statistically significantly better than the control. John Ioannidis has done numerous clever analyses that demonstrate how easily clinical research is led astray if it is not grounded in scientific plausibility. Indeed, the probability of false positive studies increases, the more improbable the modality. It is for these very reasons that we have proposed the concept of science-based medicine, which takes into account estimates of prior probability based on preclinical studies and basic scientific principles, rather than evidence-based medicine, which does not. Indeed, Wally Sampson has even proposed a “plausibility scale” for rating RCTs, and Steve Novella has pointed out how difficult it can be to interpret the medical literature. (more…)
Second, in the interest of openness and transparency, I will state my conflicts of interest up front: none. I have not talked to a drug rep in at least 20 years. Outside of a trip to San Francisco as a fellow, paid for by the company who was funding a drug study my boss was participating in, I have accepted no gifts or money of any kind from big (or little) pharma since I was a medical student. Nothing. I don’t even eat the pizza at conferences (1).
Third, I am a hospital based adult Infectious Disease doctor. I make zero money from vaccines. In fact, I only make money if people get sick with infections. For my bottom line, giving vaccines to prevent disease is counter productive to my bottom line.
I am writing this because a colleague of mine has been attacked, specifically, our fearless leader Steve Novella. J.B. Handley, Founder of “Jenny McCarthy and Jim Carrey’s Autism Organization – Generation Rescue” (whose usurpation by Jenny and Jim was apparently done in an opportunistic fashion but has had a consequence that must be galling to J.B., namely that some interviewers apparently think that Jenny McCarthy and Jim Carrey, not J.B. and his wife, are the true founders of Generation Rescue), did not like something that Steve wrote and in his characteristic fashion, has responded with a vicious ad hominem attack. Normally I wouldn’t feel obligated to put my two cents in, as Steve is more than capable of taking care of himself in a scientific argument and quite able to refute anything J.B. can throw at him. Moreover, whenever J.B. Handley attacks someone in a fashion this nasty, it is an excellent indication that the person he is attacking has scored some serious points against him. Indeed, I have twice been on the receiving end of J.B.’s tirades on the Generation Propaganda blog Age of Autism. On one occasion, he referred to me as the “worldwide wanker of woo,” and on another occasion seemed to think that I criticized Generation Rescue so harshly because I “don’t like full page ads,” rather than because I hate pseudoscience and anti-vaccine nonsense. When criticism really hits a nerve with J.B. Handley, he lashes out in a characteristic fashion. Clearly Steve’s reasoned, level-headed criticism of the latest Generation Rescue anti-vaccine propaganda initiative did just that.
In this case, however, I feel some explanation is in order because I feel a bit responsible for having brought J.B.’s wrath down upon Steve. First, a little history (albeit recent history) is in order. As I described in detail last week and the week before, Generation Rescue, with Jenny McCarthy and Jim Carrey at the fore, sometimes with J.B. himself, has mounted an impressive anti-vaccine propaganda effort. It started with a media tour promoting her most recent paean to anti-vaccine pseudoscience and autism quackery written with “co-author” Dr. Jerry Kartzinel. The book is entitled Healing and Preventing Autism: A Complete Guide, and three weeks ago Jenny McCarthy and her boyfriend Jim Carrey showed up on Larry King Live to tout a truly incompetent and intellectually dishonest “study” that purported to find that U.S. children are the “most highly vaccinated children in the world” and that that’s correlated with our higher autism rates. I would have none of it. Next, Generation Rescue introduced its equally intellectually dishonest “Fourteen Studies” website, which launched dubious attacks from pseudoexperts on fourteen of the major studies that failed to find a correlation between vaccines and autism or thimerosal-containing vaccines and autism. I wrote a lengthy post for SBM describing the utter intellectual and scientific bankruptcy of the entire enterprise. (more…)
Recently my co-blogger David Gorski wrote an excellent analysis of the latest propaganda effort from the anti-vaccine crowd – a website that attempts to deconstruct the fourteen studies most often cited to argue for a lack of association between vaccines and autism. As David pointed out, there are many more than 14 studies which demonstrate this, and no credible studies showing that there is any correlation. David covered some of the 14 discussed studies, and today I will discuss one more.
On that anti-vaccine propaganda site J.B. Handley begins his introduction with this logical fallacy:
Of all the remarkable frauds that will one day surround the autism epidemic, perhaps one of the most galling is the simple statement that the “science has spoken” and “vaccines don’t cause autism.” Anytime a public health official or other talking head states this, you can be assured that one of two things is true: they have never read the studies they are talking about, or they are lying through their teeth.
Of course this is a false dichotomy, or forced choice. I personally know of many people, including myself and David, who have both read all the studies and are telling the truth about our opinions that they do not support a link between autism and vaccines. It seems to be inconceivable to Mr. Handley that an informed professional could honestly disagree with his opinions – such is the nature of fanaticism.
I hadn’t planned on writing about the antivaccine movement again this week, so soon after having had to subject myself to yet another round of Jenny McCarthy on Larry King Live and a truly execrable Generation Rescue “study.” I really hadn’t. For one thing, there’s just so much nonsense laid down by antivaccinationists these days that it’s utterly impossible for one blogger to keep up with it all. I could write about them every single day and still not counter the sheer mass of pseudoscience, misinformation, and general ignorance that antivaccine activists spout each and every day, and because this is Autism Awareness Month lately the misinformation has been coming particularly fast and furiously. Sometimes, however, there arrives a bit of misinformation that is so egregious that it requires some response, regardless of how burned out on the topic I might be; so I guess I’ll just have to suck it up and plunge into the morass again.
The reason is that, in retrospect, I now realize that the Jenny and Jim antivaccine propaganda tour was clearly merely phase I of Generation Rescue’s April public relations offensive. In rapid succession last week, courtesy of J.B. Handley, the founder of Generation Rescue, who in order to have a couple of famous faces fronting his organization has allowed himself to be displaced, so that Generation Rescue has now been “reborn” as Jenny McCarthy and Jim Carrey’s Autism Organization (the better to capitalize on her D-list celebrity yoked to Jim Carrey’s formerly A-list (but rapidly plunging) celebrity), announced Generation Rescue’s latest initiative in a post on its antivaccine blog Age of Autism entitled Fourteen Studies? Only if you never read them.: (more…)
As hard as it is to believe, 2009 started out very promising from the perspective of actually countering the misinformation of the antivaccine movement. Antivaccine hero Andrew Wakefield, who with the help of the credulous and sensationalistic media started the entire MMR-autism scare in the U.K. a decade ago, was revealed as not just having been in the pocket of trial lawyers suing vaccine manufacturers and having been an incompetent scientist but as a scientific fraud, thanks to the investigative tenacity of Brian Deer. Thanks to Wakfield, the measles, once declared conquered in the U.K. in the mid-1990s, has come roaring back to the point where it has been declared endemic again by the ealth Protection Agency (HPA), the public health body of England and Wales. This was rapidly followed by the rejection by the Special Masters of the Vaccine Court of the claims of all the test cases in the Autism Omnibus case. It was a one-two body blow to the antivaccine movement.
Unfortunately, the antivaccine movement is nothing if not resilient. After all, the science has consistently been against each of its favorite claims, namely that the mercury in the thimerosal used as a preservative in vaccines or that the MMR vaccine causes autism. They simply move the goalposts and pivoted effortlessly to much harder to falsify ideas, such as blaming “toxins” in vaccines or proclaiming that our current vaccine schedule is “too many too soon.” After scientific setback after scientific setback that have revealed the antivaccine movement to be nothing more than the 2009 equivalent of creationists or the flat Earth movement, why would it matter to them that Andrew Wakefield has been thoroughly discredited and their signature legal action, the Autism Omnibus, has gone donw in flames? It doesn’t. Certainly it didn’t stop David Kirby from duping Keith Olbermann into chastising Brian Deer for nonexistent conflicts of interest; a group proclaiming loudly “We Support Dr. Andrew Wakefield” with a petition; David Kirby, Generation Rescue, and Robert F. Kennedy, Jr. from trying to distract attention from the defeat of the antivaccine movement in the Autism Omnibus ruling; or Andrew Wakefield himself from “complaining” to a press board about Brian Deer’s alleged misbehavior and errors. After all, science doesn’t matter to the antivaccine movement. (more…)
