The antiscience stance of the Republican candidates for President is getting so chaotic I swear I need a scorecard to keep it all straight. The latest: Michele Bachmann goes antivax.

No, seriously. Generally associated with the far left, antivaccination rhetoric reared its head at the latest Republican candidate debate. In 2007, Governor Rick Perry of Texas — and current front runner of the cohort of White House contenders — issued an Executive Order mandating the Gardasil vaccination for girls. This vaccination prevents girls from getting the human papillomavirus, or HPV, a virus that is a major factor in contracting cervical cancer later in life. This cancer has a greater than 30% fatality rate once contracted, and is a horrible, horrible condition. 20 million people in the US alone carry the virus.

Mandating vaccinations is actually something of a difficult topic, and my stand on it is somewhat nuanced (though I do lean towards saying "yes, they should be under most circumstances").

Representative Bachmann is not quite so subtle. During the recent debate, she tried to hammer Rick Perry on this issue, saying it’s wrong to mandate vaccines, saying that Gardasil "can have very dangerous side effects".

That’s pretty misleading. Gardasil’s dangers are minimal, and have been grossly exaggerated by the media. But Bachmann is going for broke with her claims; she’s now saying this:

"There’s a woman who came up crying to me tonight after the debate," Bachmann said after the debate, where she had told Perry on stage that she was "offended" by his decision. "She said her daughter was given that vaccine. She told me her daughter suffered mental retardation as a result of that vaccine."

There has never been a single confirmed case of anything like this happening (in fact, a bioethicist has offered Bachmann $10,000 if she can come up with some evidence for her statement; no word from her campaign so far). Some people do have adverse reactions to vaccinations, but they are rare (like a girl who had an extraordinarily rare mitochondrial disorder which might — might — have caused a vaccine-related problem). But mental retardation from Gardasil is totally unheard-of.

The source is incredibly suspect, too. A unnamed woman came up to Bachmann and told her this unsubstantiated story? And Bachmann goes on national TV to score points with it? The line of evidence breaks down at every step here. Bachmann saying this during a nationally televised debate is nothing short of shameful. And reckless.

She’s not the only one making hay of this, either. A PAC backing Ron Paul has a video that calls Gardasil "an STD vaccine". That a pretty cynical spin on it; the issue of vaccinating against HPV is not about sex, it’s about health. However, because HPV is contracted through sexual contact, this also plays into the far-right’s morality issues.

Generally speaking, antivaxxers tend to be to the left of the political spectrum. I doubt Bachmann is sincerely trying to woo that vote. More likely, she is just displaying more of her antiscience predilections like creationism and global warming denialism.

I also doubt Bachmann would’ve gotten the Republican nomination even before she said something like this, but mirroring the thinking of the far-left could very well sink her once and for all inside her own party. We’ll see. But don’t forget: even if and when she’s gone, we’ll still have a coterie of antireality candidates to deal with on that ticket.

Just some quick notes, to fill my quota give you some interesting reading:

2) Speaking of which, the Autism Science Foundation — a non-profit that supports real research into autism, instead of trying to link it to vaccines despite all the evidence — was chosen as the number 1 startup charity in the "Disabilities" category by Philanthropedia/Guidestar. Congrats to them! [via Dawn Crawford]

3) The Discovery Institute isn’t completely honest? Unpossible!

5) Frying pans that look like planets. Seriously. Very cool.

A couple of years back, Oprah Winfrey offered notorious antivaxxer Jenny McCarthy her own show on Oprah’s health network. Needless to say, a lot of people were unhappy about this, including me. Ms. McCarthy’s ideas about health and medicine are not only demonstrably wrong, they are what I consider to be a public health threat. She actively promotes people not taking medicine known to work, and to try things we know don’t work. That link above has copious examples.

So I was semi-delighted to hear that she will not be getting a show on Oprah’s network; apparently, she was unhappy with the negotiations and walked away.

Why only semi-delighted? According to that article McCarthy is being wooed by NBC, so she’ll still be able to sell her wares on TV, and she’ll still be getting the imprimatur of a network backing her. That’s too bad. Her beliefs about medicine are clearly contrary to what we know to be true scientifically, and people’s lives are actually impacted, hugely, by the kinds of misinformation that’s already far too prevalent out there.

Last month, Playboy magazine ran an interview with Deepak Chopra, well-known among skeptics as a man whose grasp of science is only enough to use sciencey-sounding words to bolster whatever bizarre claim he’s making this week.

I received an email from an editor of Playboy asking me if I’d like to write an OpEd about the interview to be printed in that issue. Given the long reach of the magazine (it sells more than 2 million copies per month) I agreed and quickly penned a response. The interview and my editorial, along with one by Michael Shermer, ran in that June 2011 issue [NOTE: Playboy had the interview online but now it's gone; I found transcripts but I'm not sure they're legal. If someone knows where the original link is, please let me know!]. Here is what they printed from me:

This captures the gist of what I was saying, but due to space limitations was not my entire rebuttal to Chopra’s word salad in the interview (or should that be Mad Lib?). I think it could be read as if I’m insulting people who aren’t scientists, but that’s not what I was saying. To make things clear, here, in its entirety, is what I wrote:

Reporting on the latest news about vaccinations is frustrating. For every step forward we take a step back.

1) First, the good: vaccination rate for measles in the UK has risen to its highest level in 13 years according to the UK Health Protection Agency. The rate — 90% among two-year-olds — is pretty good. I’ll note that this is for the first of two vaccinations needed; for the second dose the uptake is lower, 85%.

One bit of bad news about this is the reason behind the rate increase is thought to be due to a series of measles outbreaks in Europe. It’s an irony of life that vaccines are a victim of their own success: inoculations have been so successful in eliminating some diseases that people take for granted the diseases are gone. But they’re not gone, they’re waiting. When vaccination rates drop low enough, we see more measles. And pertussis. And the flu, and polio.

And when this happens, people get sick, and some die. A teenager in the UK recently died of measles. He had a compromised immune system, which means he relied on us, the rest of the population, to keep up herd immunity.

We failed him.

2) In Massachusetts, it is a requirement by law that children be vaccinated to enter public school. The only exceptions are due to health reasons (for example, an allergy to ingredients of vaccines) or for religious reasons. I disagree with religious exemptions when it comes to medicine — as I’ve said here and here and here– but the Massachusetts legislature is about to consider a bill that will make things much worse. The bill, if passed, will amend the previously existing law. In its entirety, the bill says:

Notwithstanding the provisions of this section a child shall, upon written request of a parent to the school, be admitted to school.

What this means is that if a parent has decided for whatever reason not to vaccinate their child, all they have to do is write a letter and the kid must be allowed to attend school. I expect the reasoning behind this bill is to allow parents more freedom, but what it will actually do is greatly increase the risk of other children at Massachusetts schools for contracting serious and potentially life-threatening diseases.

The sponsor, John Keenan (D-Salem), appears to be a public safety-conscious man, having sponsored many bills to increase public safety. Going over his record I find myself agreeing with many of his policies. But this one strikes me as a bad idea.

Harpocrates Speaks has much more on this. If you live in Massachusetts, I suggest you read his article and contact your local representative about this issue.

A few months ago I posted about the Autism Science Foundation: an organization that funds real research into autism. We don’t know what causes autism, but ongoing research is making progress, and ASF is helping support that.

For today only, they are featured on the Philanthroper home page. Philanthroper is a group that helps raise money one dollar at a time. I like this idea. Giving a dollar isn’t all that hard for a lot of people, and the process is pretty painless: if you have a buck and a Paypal account, it takes less than a minute.

A lot of time, money, and effort is being wasted looking into a connection between vaccines and autism when we know no such connection exists. I’m glad there are groups out there trying to find the real causes, and that’s why I already donated to ASF.

So. Got a minute and a buck?

The number of confirmed cases of measles in the United States stands, as of this moment, at 152.

That’s twice as many cases as usually seen in a year, and it’s only June.

Why so many? In the article linked above, it’s made clear: parents aren’t vaccinating their kids. The reasons for that are numerous: religious exemptions, anti-vaccination propaganda, ignorance, or perhaps even just laziness. But the bottom line is that kids are getting sick.

And if you don’t think measles is that big a deal, watch this:

That is one of many stories from people who have dealt with their children getting sick… and some who have had their children die. The website Shot by Shot gives the very human and all-too-often tragic side of what happens when people don’t vaccinate. The site is put together by the wonderful people at California Immunization Coalition.

The leaders of the antivaccination movement say they speak out because they care about the children. When I see stories like these, from parents who are destroyed by the loss or serious illness of the children, I question those antivaccination advocates. And we know that when trying to sway opinion, just stating facts rarely works against antiscience claims like those of antivaxxers. I’m hoping that more parents see stories like the ones at Shot by Shot. We have the facts on our side, but we also need to touch these parents’ hearts before they’ll see the truth.

Thanks to my friend and one of my heroes, Dr. Joe Albietz, for the link to these stories.
