Should Vaccines Be Compulsory?

In the US children must have proof of vaccination before entering the public school system, although it is becoming easier in many states for parents to gain exemptions from this requirement. In the UK there is no such requirement. This distinction has allowed for a comparison of the impact of scaremongering about the safety of vaccines and the effectiveness of campaigns to improve vaccination rates.

In the UK the scare that the MMR vaccine may be connected to autism (it isn’t) triggered by the bogus study by Andrew Wakefield resulted in a precipitous drop in vaccination rates down to about 78% overall. This is far below what is necessary for herd immunity, when immunity is prevalent enough to prevent a disease from spreading around a population. And the 78% figure is an average – but there are pockets where the number is even lower. This resulted in a surge of measles – from a low of less than 100 cases per year to 1,348 cases in 2008. The surge contniues despite an aggressive campaign to inform the public about the safety of the MMR vaccine.

By contrast the US has seen continued high overall vaccination rates of about 90%. The MMR and other vaccine scare came to the US a bit later than the UK but it is in full swing here, without much effect on overall vaccination rates.  However, we are beginning to see the emergence of low vaccination rates in specific communities, with subsequent outbreaks of measles (131 cases in 2008), mumps, and whooping cough.

The Oprah-fication of medicine

OprahUnfortunately, a frequent topic on SBM has been the anti-vaccine movement, personified these days by celebrity spokesmodel for Generation Rescue Jenny McCarthy and her dimmer than dim boyfriend comedian and actor Jim Carrey. Unfortunately, it is a topic that is unlikely to go away. We’ve all speculated why the anti-scientific emotion-based notion that vaccines somehow must cause autism persists in spite of mountains of evidence to the contrary, but I think the question goes much deeper than that because it’s not just about vaccines. The anti-vaccine movement is but one of the most visible components of a much deeper problem in our public discourse, a problem that values feelings and personal experience over evidence, compelling stories and anecdotes over science.

I’m referring to the Oprah-fication of medicine in America.

Does the Flu Vaccine Increase Hospitalizations?

The Centers for Disease Control (CDC) currently recommends that children 6 month to 18 years old receive an annual flu vaccine. There are two types of flu vaccines used in the US: a live attenuated virus (LAIV) and a trivalent inactivated virus (TIV) vaccine. Both are safe and effective  – while efficacy varies from year to year, they are 70-90% effective in healthy adults. Efficacy is young children appears to be slightly less, about 66%.

There remains, however, many sub-questions about the flu vaccines and by the time researchers have thoroughly explored them vaccine technology is likely to have progressed, and therefore any new vaccines will have to be tested all over again.

One of those sub-questions about vaccine safety and efficacy is the net effect of the flu vaccine in children with asthma.  Some have raised concerns that the vaccine may exacerbate asthma, a 1-2% increased wheezing and 3% increased hospitalizations have been reported, although so far the bulk of the data suggests that both types of flu vaccines are safe in children with asthma.  There is evidence to suggest that the LAIV may be superior to the TIV in children, particularly with asthma.

Chemical castration for autism: After three years, the mainstream media finally notices

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.

Hostility Towards Scientists And Jenny McCarthy’s Latest Video

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.

Georgia on my mind

Scales

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.

The Huffington Post‘s War on Medical Science: A Brief History

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 Post has 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.”

Where’s the outrage?

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.

Antivaccine hero Andrew Wakefield: Scientific fraud?

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:

  1. Choices Should Have Consequences: Failure to Vaccinate, Harm to Others, and Civil Liability by Douglas S. Diekema.
  2. Parents Should Not be Legally Liable for Refusing to Vaccinate their Children by Dr. Jay Gordon.
  3. Unintended Consequences: The Primacy of Public Trust in Vaccination by Jason L. Schwartz.
  4. Challenging Personal Belief Immunization Exemptions: Considering Legal Responses by Alexandra Stewart.
  5. Gambling with the Health of Others by Stephen P. Teret and John S. Vernick.
  6. 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.
