There are times when reality is so obvious, so clear, so rock-solid 100% amazingly in-your-face incontrovertible, that it is beyond belief that anyone could deny it.

And yet, antivaccination groups exist.

Let me be very, very clear: they are wrong. Vaccines save lives. Vaccines save millions of lives. And not just directly, like they did by wiping out smallpox, a scourge that killed hundreds of millions of people. But also, through herd immunity, vaccines save infants too young to be vaccinated, the elderly with weak immune systems, and people whose immune systems are compromised due to chemotherapy, genetic issues, or because they are taking immunosuppressants for other illnesses (like arthritis).

Vaccines don’t cause autism. Vaccines don’t contain dangerous levels of mercury. Vaccines don’t contain fetal tissue. Each of these – and many, many more — is misinformation spread by antivaxxers, statements that are easily proven wrong (like, in order, here, here, and here). But many antivaxxers continue to use them.

What does that say about their willingness to tell the truth?

Yesterday, in Australia, one of the most vocal antivaxxers alive, Meryl Dorey of the grossly misnamed Australian Vaccination Network (AVN), spoke at the Woodford Folk Festival about her beliefs. However, she didn’t get quite the chance she had hoped for. Once the news got out that she was invited to the festival, the group Stop AVN went into action. A protest cry went up, and the venue was changed from her speaking solo, to her participating in a panel with a series of experts — actual, real experts — on vaccines. As I write this, I have a window open on Twitter, and I’m watching the tweets using the hashtag #StopAVN flow by. It’s a thing of beauty. Dorey’s arguments are being destroyed, 140 characters at a time.

The bottom line, repeated over and over again: Vaccinations save lives. That statement of fact is so simple, so powerful, that Stop AVN put it on a banner and had it flown behind a plane at the festival.

Wonderful! My congratulations to my friends Down Under for this impressive campaign.

But we here in America cannot rest easy. We have antivaxxers here; loud, wealthy, ones, who won’t hesitate to spread the same kind of misinformation; dangerous misinformation that poses a serious health threat.

The National Vaccine Information Center is one such group. They have a long history of antivax rhetoric, remarkable only in its breathtaking inaccuracy, and their ability to get it into the mainstream. And they’re at it again: they’ve put an ad on ABC’s digital 5000 square foot screen in Times Square in New York City, a place that will be packed with people celebrating the new year. To top it all off, Jenny McCarthy — who dispenses incredibly dangerous and incredibly wrong advice about vaccinations and other health safety issues — is slated to be a guest on ABC’s New Year’s Rocking Eve with Dick Clark… and she has stated she plans to promote her dangerous nonsense on the show.

Skepchick has an excellent post about this. My friend Jamie Bernstein has started a petition on change.org to get the ad taken down. I signed it.

Again, let me be clear: these antivax groups pose a public health threat. If you don’t believe me, then read this account by someone who knows.

And if you wonder why I feel so strongly about this, then I suggest you steel yourself — seriously — and read this account written by the parents of Dana McCaffery, who lost her life to pertussis when she was four weeks old. She was too young to be vaccinated. Because vaccine rates were so low in her area, pertussis had a place to grow. She was infected, and she died.

You want to know why I feel so strongly? This is why. She is why.

Talk to your board-certified doctor about vaccines. Find out what you might need — being an adult doesn’t mean you’re exempt from childhood vaccines; you may need a booster — and if your doctor approves, then do what needs to be done.

The solution against the antivaxxers is to make sure their misinformation is countered by facts. It’s one of life’s great ironies that vaccines have helped these people live as long as they have to spread their nonsense about vaccines. We can speak up to stop them… and at the same time get vaccinated to make sure that they — that everyone – gets a chance to be wrong for a long, long time.

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.

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.

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?

Pertussis, known commonly as whooping cough, is a highly contagious disease. It’s bad for anyone to get, but in infants it can result in death.

We have a vaccine that inoculates people against the bacterium. Yet, because not enough people get this vaccine, we’re seeing pertussis (and measles) outbreaks in many, many places. And who suffers? Babies too young to be vaccinated.

I want you to watch the following video. It’s a segment on the Australian 60 Minutes program, which deals with this issue plainly and truthfully. It’s an extremely difficult video to watch, as you’ll see (I had to turn my head several times, to be honest) but it’s also extremely important that everyone sees it.

Pay close attention to antivaxxer Viera Schiebner. Watch her demeanor, her manner, her attitude. This is a leader in their movement? To say her view of medicine, of reality, is skewed is to seriously understate the case. Barbara Holland Bronwyn Hancock, who works with Schiebner, justifies not getting vaccinated by making the outrageous statement that diseases can be beneficial.

I fail to see how exposing infants to potentially fatal infections is beneficial in any way.

Mia Freedman has written an excellent article about this. Apparently, only 11 8% of adults in South Australia, are vaccinated against pertussis [the 11% number is an average for all of Australia, my apologies for any confusion]. It’s tempting to blame the antivaxxers for this, but I wonder. I know a lot of my readers here are not antivax, but how many have had their Tdap booster?

I have. As much as I talk about this issue, I didn’t know I needed a booster shot for tetanus, diptheria, and pertussis until recently. As soon as I found out I went to my doctor and got the vaccination. Pertussis is spread by unvaccinated adults carrying the bacterium, so getting the booster shot will help lower the reservoir of hosts.

Getting the booster may not save your life, but it could very well save the life of an innocent infant too young to be otherwise protected. Go see your doctor, ask them about it, and if they recommend it, get the booster.

My thanks to Richard Saunders for the video, and to David McCaffery — who appears in the above video with his wife Toni — for the link to Ms. Freedman’s article. David’s daughter Dana would have been over two years old now if she hadn’t succumbed to pertussis at the age of just four weeks.

There’s a grand irony about skepticism and alt-med groups that I suspect most people don’t know. Skeptics are commonly seen as curmudgeonly cynics, poopooing new ideas and excluding anyone not in their club. Alt-med people are seen as warm, open, willing to try new things, and welcoming anyone to their group.

But that’s not the way it really works. In fact, skeptical groups welcome people who believe in various things we don’t (we’ve had them come to various TAMs; the effort we make in outreach could be improved, of course, but we certainly don’t turn them away — an important point, as you’ll see in a moment), and alt-med groups… well, they talk a good game, but when it comes down to a skeptic actually showing up at their meetings, their actions speak much louder than words.

But don’t take my word for it. You can read all about what happened to my pal and active supporter of real medicine Jamie Bernstein when she attended the antivax Autism One convention. She wrote up her experience in two parts: the first on Skepchick, and the second on Friendly Atheist.

The upshot? Despite behaving herself, obeying the rules, and being very polite, she was escorted out of the meeting by three security guards and four armed police officers, ejected on clearly trumped-up charges.

As Orac points out, does this sound like an open and honest movement? Or does it sound like people who are terrified of different opinions and quash dissent, even before it happens?
