Get Vaccinated Against Inanity


This is a manifestation of what I call the “Truther” syndrome – that malady that causes somebody with incomplete (or non-existent) knowledge of a topic to assume that they are nevertheless an expert, and that they are capable of making pronouncements on the topic that are every bit as relevant as those of bona fide experts.  Whenever a person says “Jet fuel can’t melt steel beams”, or “Astronauts cannot survive passing through the Van Allen radiation belts,” or “Unvaccinated children don’t pose a threat to vaccinated children”, he or she is exhibiting symptoms of “Truther” syndrome.  Unfortunately, there seems to be no cure for this puzzling ailment, or more precisely, the twin treatments that might be successful – rigorous study and critical thought – are often rejected by the patient.

For those who already recognize the insipid stupidity of this meme, let’s give you a booster shot.  Vaccines, as you know, are injections filled with weakened or dead pathogens.  The idea is simple: your body mounts an immune response to the non-threatening germs, which it then “remembers” for future use.  If you ever do encounter a live version of the bug in question, your body has a ready-made defensive line already in place.  In theory, your body can defeat the invaders before you ever get sick.

Not every disease has a vaccine, of course – as of now, there still isn’t a vaccine for human immunodeficiency virus (HIV), cytomegalovirus (CMV), dengue fever, or malaria, to name just a few of the more serious afflictions that may befall a human being.  And of course, those vaccines that do exist have varying levels of effectiveness.  Generally speaking, vaccines successfully immunize their recipient between 95 and 99 percent of the time; in other words, for every 100 people that receive a particular vaccine, 95 to 99 will be protected from that disease should they ever be exposed to the germ that causes it.

But that still leaves 1 to 5 people who aren’t protected by vaccines.  For various reasons, vaccines simply don’t take for some people.  Those people for whom a certain vaccine is not effective – or who are too young to receive the vaccine – or who are allergic to ingredients used in the vaccine – or whom haven’t been vaccinated long enough to reap the full benefits of the vaccine – rely on herd immunity to protect them.

People are social animals who tend to live in big germ-swapping groups.  If a lot of people in a population are immune to a disease, that prevents the disease from establishing a toehold in the community.  In other words, the vaccinated members of a community provide a wall for the unvaccinated; however, there must be a sufficiently large number of vaccinated people to prevent the disease from spreading.  The more infectious the disease, the more vaccinated people are needed to establish herd immunity.  For a disease like measles, herd immunity requires that about 95% of a population be vaccinated.

Vaccines do work most of the time.  They are certainly right up there with hand-washing as a means of preventing the spread of disease.  In the few instances where they don’t work, however, a person needs to be surrounded by others who can shield him or her.  To refuse to vaccinate yourself and your children based on groundless fears amounts to anti-social behavior.  Your “Truther” syndrome, against which you failed to vaccinate yourself by learning to think critically, will result in physical maladies and possibly even death for other people.  There is no sense in anybody dying from a preventable disease, but that is exactly what anti-vaxxer attitudes have led to.

Wag the Ebola Dog

Ebola Distraction

I realize that facts are anathema to most conspiracy theorists, but let’s inspect them anyway, just in case this meme is…you know…incredibly stupid.

First, Mr Contemplative Chimp: Ebola did not just “up and vanish”.  As of December 9, 2014, Ebola is an ongoing threat in West Africa.  To date, nearly 18,000 people have been infected and more than 6,600 have died in the most widespread Ebola outbreak in history.  I’m sure the people of Mali, Guinea, Sierra Leone, and Liberia would be thrilled if Ebola “up and vanished”, but that hasn’t happened.

I suppose you mean that Ebola “up and vanished” in the United States, but that’s not accurate either.  Despite peoples’ concerns, Ebola was never a major threat in the United States.  There were four patients diagnosed with Ebola in the United States at the height of the US “outbreak”, one of whom passed away from the disease.  And Ebola didn’t vanish; healthcare officials aggressively attacked the virus and contained its spread; subsequently, the remaining three patients recovered.  Their cases have been well-documented; it’s not as if they were just swept under the rug, never to be heard from again.

Now I think the US public’s reaction to Ebola was vastly overblown.  There was no need for the 1980’s-AIDS-like panic that sprang up around a very small number of cases, and yes, the media did their part in fanning the flames of unease.  But just because we blew this all out of proportion, that doesn’t mean Ebola was a “Wag the Dog” distraction from some deeper evil.  Sometimes, bad things just happen, and they can happen without government assistance or complicity.

But just for the sake of examining this issue thoroughly – and I know I’ll regret asking this – prithee tell: from what was the Ebola scare meant to distract us?

Mike Shepard contends in an opinion piece written for DC Gazette that Ebola’s foray onto American soil was entirely manufactured.  What evidence does he present in support of this audacious claim, you may justifiably ask?  He claims that if Thomas Duncan had really been carrying Ebola when he boarded a plane in Liberia bound for Dallas, Texas, then all of his traveling companions should have been infected.  After all, Shepard says, airplane passengers breathe recycled air.  One person’s disease is everybody’s disease on an airliner.

Of course Shepard completely ignores the well-established fact that Ebola is not an airborne virus, nor is it possible for a patient to spread the virus until he becomes symptomatic.  Duncan was not yet symptomatic when he boarded the plane to Texas; therefore, it would be extremely unlikely for anybody to catch the virus from him at that time.  The fact that the passengers of Duncan’s flight did not contract Ebola does not diminish the reality of Duncan’s unfortunate demise from that disease.

But Shepard is not content to spew just one egregious piece of misinformation.  Later, he asserts – naturally, without a shred of evidence – that the pseudo-Ebola scare was cooked up by none other than…ominous chord, please…President Barack Obama himself.  In Shepard’s paranoid fever dream, President Obama is plotting a major jihadist war against America.  What was Ebola’s role in all of this?  It was meant to distract the public while Obama sent his lackey John Kerry to smuggle ISIS operatives across our border.

I would understand if you thought I was making this up.  Nobody can be that paranoid, can they?  Nobody can be that blinded by their irrational hatred of President Obama, can they?  Well, read Shepard’s piece and judge for yourself: he really seems to believe his paranoid claptrap.

Okay, Shepard is a nutjob.  Is there anybody more rational that can show how Ebola was a manufactured distraction?

Ingri Cassel, the Director of Vaccination Liberation, thinks she can.  According to a flyer written by Cassel, Ebola isn’t even a naturally-occurring disease.  Cassel believes that the United States invented Ebola, and she has a patent application as “proof”.  (In fact, the CDC holds patents for several microorganisms and viruses, as Snopes explains, but not because it invented them.  The patents are meant to prevent for-profit organizations from patenting the organisms and extorting money from governments for research rights.)  Cassel charges that the government’s intention was to cause an epidemic and then to profit enormously from vaccine sales.  It should come as no surprise to anyone that the director of an organization called Vaccine Liberation takes a dim (and hopelessly misguided) view of all things vaccine-related.  No wonder, then, that Cassel has fallen into the conspiracy-thinking trap.  Anything she doesn’t understand, she adopts as “evidence” for that which she already believes.

Cassel’s contemptible claims do not end there.  She thinks that the ersatz Ebola outbreak is actually a vaccine-implemented sickness being used as an excuse to move troops into West Africa.  And why should the United States or any other country want an excuse to move troops into West Africa?  Why, to steal the region’s newly discovered oil reserves, of course.  It all makes sense, as long as you don’t let pesky things like facts get in your way.

Cassel’s ill-informed paranoid conspiracy theory goes on for almost two pages and draws heavily from the work of other conspiracy theorists.  After reading her flyer, one is filled with sadness – not because we actually live in the bizarro conspiracy-ridden world she suggests, but because she feels compelled to grasp at nonsensical straws to support her dangerous ideology.

I found a few more pages attempting to explain why Ebola is a distraction from something far more sinister, but the opinions of their authors seemed to fall along similar lines.  I haven’t the energy to recap each one, so I’ll conclude by saying this:  The Truth is out there, conspiracy theorists, but you cannot see it unless you’re willing to suspend your pre-formed beliefs.  You think that everybody else is blinded by complacency; I submit that you are blinded by your inflexibility.

Who’s The Denier?

autism deniers

One of the greatest theoretical gifts of the Internet, in my opinion, is that it grants nearly unfettered access to all sorts of scientific data. Unfortunately, many of the people who access and attempt to use scientific data have no formal scientific training. Trying to analyze data when you’re not trained to do so is akin to performing open-heart surgery without the benefit of a medical school education. It leads to gross mistakes, which leads to wrong ideas, which leads to memes like this one.

But before I dismiss this meme as so much poppycock, let me give it a fair shake. I did a bit of digging on the three supposedly inept officials pictured in this meme, and on the alleged surge in autism cases over the past few decades. Dr Thomas Insel, Director of the National Institute of Mental Health (NIMH) acknowledges that diagnoses of autism spectrum disorder (ASD) have increased dramatically in the last few decades. He notes that doctors have expanded the definition of ASD to include many children who might previously have been diagnosed with a different condition; also, ASD testing has become more sensitive, allowing for the diagnoses of mild autism cases that could have escaped detection in previous years. But Dr Insel does not stop there; he also points to an alarming increase in other childhood ailments, including asthma, Type I diabetes, and food allergies. If environmental factors are contributing to an uptick in those other conditions, perhaps there is some external factor causing a greater incidence of ASD in children. Dr Insel believes that the cause behind the uptick in autism diagnoses is probably a combination: there are more children being affected, and more being detected. Those hardly sound like the words of an autism denier.

Dr Marshalyn Yeargin-Allsop and Dr Coleen Boyle gave a press briefing in March to talk about the growing ASD epidemic. They both say that ASD diagnoses are increasing, and stress that further research is needed to explain why. They mention the improvement in diagnostic practices but say little about the possibility that environmental factors are leading to an increased incidence rate of ASD. Dr Yeargin-Allsop and Dr Boyle are not deniers; they are cautious scientists who do not wish to hang their reputations on unsupported speculation.

If only everyone else felt the same way…

So we can dispense with the notion that these doctors are autism deniers, or that they are culpable for the apparent increase in ASD during their tenures. Why would anyone suggest otherwise?

In my research I came across a letter drafted by several “concerned organizations” that expressed the same sentiments contained in this meme. They charge that the CDC and NIMH are refusing to investigate environmental causes behind the ASD epidemic (which is patently untrue, as per Dr Insel’s article) and demand that President Obama remove these people from their posts. They claim that it is impossible for a genetic autism epidemic to arise in a single generation and that there is no “autism gene”; ironically, the three doctors they lambast would probably agree with them. Most health experts believe that autism is the result of genetic and environmental factors; in other words, there is no single cause (or gene) that makes a person autistic.

The entire scientific community is still struggling to understand the causes and nature of ASD, yet the creators of this missive (and this meme) have painted themselves as experts. How wonderful it must be to possess certainty when the best and brightest minds – the people who have spent a lifetime training to interpret scientific data – are still scratching their heads.

One thing the letter and meme do not do is provide an actual culprit for the alleged ASD epidemic. If ASD isn’t genetic (as the “concerned organizations” assert), then what environmental factor could be causing it? Thankfully, some of the “concerned organizations” are listed at the end of the letter with links to what are sure to be fact-filled websites. Click on a few of them and it becomes clear that one word is on all of their minds:


From Age of Autism (emphasis mine):

We are published to give voice to those who believe autism is an environmentally induced illness, that it is treatable, and that children can recover. For the most part, the major media in the United States aren’t interested in that point of view, they won’t investigate the causes and possible biomedical treatments of autism independently, and they don’t listen to the most important people – the parents, many of whom have witnessed autistic regression and medical illness after vaccinations. We do all those things, and more.

From Autism Action Network:

Autism Action Network is a national, non-partisan, grassroots, political action organization formed by parents in support of children and adults with autism, vaccne (sic) injuries, and neurodevelopmental and communication disorders.

From Canary Party:

The proper definition of safety involves a clear vision of the larger goal of regulatory work, which is securing positive health outcomes for children and families. This vision of safety requires a commitment to a total health perspective, including chronic as well as infectious disease, developmental disability as well as episodic illness, and quality of life as well as the absence of disease. It embraces a philosophy that sets a goal of zero vaccine and other medical adverse events, where these events are treated respectfully, indeed, as a resource for prevention of future adverse reactions. Achieving this goal requires a strong and global commitment to safety science, especially the study of health outcomes in vaccinated and unvaccinated populations.

From the Elizabeth Birth Center for Autism Law & Advocacy (EBCALA):

The autism community faces severe legal hurdles in many areas, including special education, insurance, healthcare, family law, criminal law and tort law, particularly related to vaccine injury. Since 2009, EBCALA has organized an annual conference each May in Chicago, Illinois during the Autism One conference to address the unique legal needs of the autism community.

From Generation Rescue:

Generation Rescue firmly believes that all parents have the power of choice – to vaccinate or not – and should be armed with the right questions to make an informed decision. We encourage all new parents to educate themselves about vaccinations so they can stand with confidence behind their decisions. Parents need to discuss vaccination options directly with their child’s pediatrician.

From Thinking Moms Revolution (in response to a question about doctors who refused to treat a mother’s unvaccinated child):

While I cannot give you advice on finding an MD who shares your (valid) concerns about immunization, I can tell you what I did for my sister when she lived in North Carolina. I asked around at all the local health food stores, yoga studios, and complementary health clinics for names of all-round well-recommended health professionals, and created a short-list for her with the names which had come up 3x or more.
From that list, there was an osteopathic doctor, a naturopathic doctor, and a traditional chinese medicine doctor, only one of which was covered by her insurance. She sees that osteopath every time she goes back, even though she’s moved overseas.

All of the “concerned organizations” who signed the letter that inspired this meme express a strong concern about vaccines (with the exception of the Holland Center, whose website doesn’t mention vaccines at all as far as I can tell). Let’s be clear, if you run an autism awareness website, there is no scientifically valid reason to mention vaccines at all, unless it is to debunk this dangerous misconception. Science-Based Medicine has a lot to say about the safety of vaccines, and many other scientific institutions, many of them operating independently, have offered their assurance that vaccines are not connected to autism at all. If there is an environmental factor contributing to a rise in the number of children affected by ASD, it isn’t vaccination.

So what about this meme? Well, it doesn’t specifically mention vaccines, but it is spawned by a mindset that clearly believes there is a link between vaccines and autism. Therefore I will go with my original impression: this meme is hogwash, and not to be taken seriously.

If It’s On The Internet…

Total BS

If you’ve spent any time around humans, you’ve probably noticed that we’re not a rational bunch. We tend to draw conclusions based on our personal prejudices rather than empirical evidence. When confronted with conflicting evidence, we often reject it out of hand. I’m as guilty of this as everybody else; I think it’s a defense mechanism meant to keep our minds from having to reconstruct our worldviews on a daily basis. Evolutionarily speaking, it’s good for us to have a consistent image of how the world works.

Fortunately, we’ve recognized this shortcoming and invented science as a means of by-passing it. We humans use science to know about the natural world, but also to improve the quality of our lives. One of the greatest practical achievements of science is medicine, that vast branch that helps determine what’s good and bad for us.

Of course, not everybody accepts the findings of science/medicine, because – as I pointed out – it’s a lot more comfortable to stick to your ideological guns. Every now and then you’ll come across a meme like this one, which seems to fly in the face of established science. It’s tempting to dismiss this meme as so much bollocks, but let’s take the time to see what evidence is available to confirm or refute each of the author’s claims.

Exposure to the sun generates vitamin D which will protect you from cancer.

If you want to stir up a poop-storm of controversy, nothing stirs faster than the topic of cancer (not the Tropic of Cancer, which to the best of my knowledge is not controversial at all). Claim that something causes or prevents cancer, and soon you’ll have a multitude of angry self-proclaimed medical experts beating down your door to tell you why you’re wrong. Unfortunately these armchair physicians seldom come armed with peer-reviewed studies. What do the real experts have to say about the Sun, vitamin D, and cancer?

According to the National Cancer Institute, an arm of the National Institute of Health, the link between vitamin D and cancer is not well-understood. Here’s what we do know:

Vitamin D helps the human body process calcium and phosphorus, which are essential for healthy teeth and bones. Your skin does indeed produce vitamin D when exposed to sunlight, but you also get vitamin D in your food. What’s the connection between vitamin D and cancer? Early studies indicated that certain types of cancer were less common – and less often fatal – in people living close to the equator than in people living at higher latitudes. One proposed hypothesis was that since equatorial inhabitants receive more direct sunlight, their bodies produce more vitamin D. Vitamin D does seem to inhibit cancer growth in mice; perhaps something similar is happening in people? Sadly, further studies have been inconclusive. At present, there is little data to indicate what benefit, if any, vitamin D has in keeping people cancer-free.

Furthermore, there are many types of cancer: the NCI never mentions a specific link between vitamin D and skin cancer, which is the kind of cancer most often associated with excessive exposure to sunlight. So, even if vitamin D does protect you from some types of cancer, it might not protect you from skin cancer; ergo, you should probably stock up on sunscreen if you’re going to be outdoors a lot, right? Right?

Sunscreen contains chemicals that actually give you skin cancer.

Ah, so this is the author’s angle. Silly people: the Sun doesn’t cause cancer – the cream you rub on your skin to protect yourself from cancer causes cancer! What cruel irony!

Well, not so fast. Dr Ronald Siegle, writing for the Skin Cancer Foundation, debunks rumors regarding the potential carcinogenic properties of sunscreen. According to Dr Siegle, there is no compelling evidence that the ingredients in sunscreen present a cancer risk to humans. So why do some folks think otherwise?

Probably because some sunscreens contain titanium dioxide nanoparticles. Titanium dioxide in powder form is highly toxic when inhaled, and a possible carcinogen to humans. Some people are concerned that the tiny titanium dioxide particles in commercial sunscreens could penetrate through the skin and enter the bloodstream. Dr Kenneth Portier, writing for the American Cancer Society, says that scientists have been unable to determine what amount of TiO2 actually makes it through the outer layer of skin cells, and to what depth. Dr Portier also points out that not every brand of sunscreen contains titanium dioxide, and echoes Dr Siegle in saying that overall, applying sunscreen is still a smart idea if you’re going to be outdoors. Despite what some people say, sunscreen helps reduce the risk of skin cancer, so slather up.

Al Qaeda is the CIA and your government is the major threat.

This statement opens many cans of worms.

It has certainly been rumored that the United States armed and supported Al Qaeda during the latter operation’s formative years. Is there any truth to these rumors? Predictably, that depends on who you ask. The supposed link between the CIA and Al Qaeda goes back to the Soviet invasion of Afghanistan. The United States, in an effort to stymie the Soviets, provided support to the local Afghan mujahideen (Islamic guerilla fighters), but denies ever having been intimately connected with so-called foreign, or Arab, mujahideen who laid the foundation of Al Qaeda. United States government officials argue that there were plenty of indigenous mujahideen invested in repelling the Soviet invasion force; ergo it was unnecessary to bring in foreign fighters, particularly those who were already well-funded by Muslim sources and openly hostile to Americans.

Remarkably, Osama bin Laden, a co-founder of Al Qaeda, agreed with the United States government’s portrayal of the U.S./Al Qaeda relationship in those early years; i.e. that there was none. And yet…

Other sources, notably Saudi Prince Bandar bin Sultan, have claimed that Osama bin Laden expressed gratitude toward the United States of America for its role in helping the Afghan mujahideen. This seems to contradict most other depictions of Osama bin Laden, who was never portrayed as being a fan of the United States.

Flash forward to September 11, 2001, when terrorists linked to Al Qaeda hijacked four airplanes and intentionally crashed three of them into the World Trade Center and the Pentagon. Despite an extensive investigation showing that the 9/11 attacks were in fact the act of a radical Islamic terrorist organization, many conspiracy theorists leapt headfirst into the conclusion that the United States government either orchestrated the attacks themselves, or knew about them beforehand and was complicit in allowing them to happen.

The conspiracy theorists point to what they perceive as inconsistencies and physical impossibilities in the events leading up to the attacks. I don’t have the time or energy to review and debunk every conspiracy theory that has popped up in the wake of 9/11 (nor do I need to, as many sources, Popular Mechanics, e.g., have already done so). I don’t expect the diehards to be convinced; conspiracy theories are born of a need to have an explanation that fits one’s prejudices, regardless of whether the explanation is true or even plausible.

So where does that leave us? Is Al Qaeda the CIA? Is our government a major threat? There’s no evidence to support a positive answer to the first question, and I don’t think the second question even has a defensible answer. Sure, the government has done some shady stuff; in fact, it continues to do so. But just because our government has done some bad things doesn’t mean it has done every bad thing. We must be careful when leveling such accusations.

Diet products contain aspartame and aspartame causes brain cancer.

Some diet products contain aspartame, but aspartame has never been scientifically linked to an increased risk of brain cancer in humans. Many of the misconceptions about aspartame are probably connected to a hoax email that has been circulating since at least 1998. The Food & Drug Administration has responded to the email, saying that it is full of pseudoscientific nonsense. Both the National Cancer Institute and the American Cancer Society attest to the safety of aspartame and other artificial sweeteners.

“But wait a minute,” you might say, “What about that study showing that aspartame increased cancer risks in men who drink diet sodas?” People who already wanted backing for their pre-formed conclusions that aspartame was dangerous leapt on the report like a lion on a gazelle. They seemingly had their smoking gun. Nevermind that the report’s authors – who pre-maturely promoted it – recanted their support almost immediately when the report was finally released. They called their own findings weak and untenable; in other words, they no longer felt comfortable hanging their confidence on it. Similar studies purporting to show hidden dangers in aspartame have likewise been called methodologically unsound by the international scientific community. Aspartame is one of the best-tested food additives in existence, and the available evidence – from laboratories all over the world – shows that it is safe.

Mammograms expose you to ionizing radiation which will give you cancer.

Life exposes you to ionizing radiation. Every day, every second, your body is being bombarded by charged particles and high-energy photons moving at fantastic speeds. Although these particles are sub-microscopic, they pack quite a wallop on the molecular scale; in fact, they can damage your sensitive genetic code.

In many cases your cells are able to catch the damage and repair it before it can spread. In other cases the cell is sacrificed to save its host: you. Your body has myriad ways to protect itself from the effects of ionizing radiation.

In very rare situations, a cell suffers a mutation that shuts off the mechanism that tells it when to stop growing. If your body’s defense system fails to identify and destroy the cancerous cell, it will grow and divide out of control, threatening the survival of tissues, organ systems, and eventually its own host. It’s a testament to the power of our immune systems that these aggressive cancers seldom get beyond the single-stage cell, but when they do, the results can be devastating.

If we increase our exposure to ionizing radiation, we increase the likelihood of developing cancer. Scientists have made careful measurements and estimates of the amount of radiation received in various situations, and these measurements inform dosage recommendations. Check out this website to learn about how much radiation is too much. While you’re there, be sure to click on the diagram for a closer look; it’s really informative.

As you can see, the average radiation dose from a mammogram is 3 milliSieverts. The maximum yearly dose permitted for U.S. radiation workers is 50 milliSieverts, so you could have sixteen mammograms in a one-year period without exceeding the recommended maximum dose for people who routinely work in high-radiation environments.

You would have to receive a yearly dose of 100 milliSieverts (about 33 mammograms) before you had an increased risk of cancer. I don’t think too many people will receive 33 mammograms in a year. Bottom line: the radiation you receive during a typical mammogram is far below the level needed to increase your risk for developing cancer.

To be fair, it takes only one radiation particle to get the cancer ball rolling. The longer you live, the more likely you are to take a critical hit in your DNA. Ironically, that makes it more important that women over 50 get regular mammograms. It’s a measured risk: the microscopic impact in your yearly radiation budget is more than countered by the likelihood that you’ll detect breast cancer in its early stages.

Most vaccines contain thimerosal (mercury) that will kill you.

In a word, no. Thimerosal is not mercury; it is an organic compound that contains mercury. That’s an important distinction, because it changes how the chemical is absorbed and processed inside the body. Many vaccines used to contain thimerosal as a preservative because it would prevent the growth of harmful bacteria in the vaccine medium. According to the USFDA, thimerosal was eliminated or reduced to trace amounts in most vaccines in response to growing concerns about its safety. Today, most of the vaccines recommended for children under 6 are thimerosal-free, with the exception of flu vaccines (and you can even request a thimerosal-free flu vaccine). Contrary to this meme’s assertion, most vaccines do not contain thimerosal.

Now let’s address the second part of the statement: can thimerosal kill you? Well, it’s no secret that mercury is exceedingly bad for you, but different compounds of mercury behave in different ways. Thimerosal is a derivative of a compound called ethylmercury. The Center for Disease Control explains that ethylmercury, unlike elemental mercury and methylmercury, is broken down and eliminated by the body. It doesn’t slowly accumulate to dangerous levels; furthermore, the few vaccines that still contain thimerosal have it in exceedingly low concentrations.

You’ve no doubt heard stories of people who claim that they or their children were made ill by a vaccine. There will always be people who react badly to certain vaccines, but it almost certainly has nothing to do with mercury. As with mammograms, vaccines represent a miniscule risk, and the benefits far outweigh it.

One more question needs answering: if thimerosal is so harmless, why did the FDA request that vaccine manufacturers remove it from most of their products? The FDA and its European cousin, the AAP, followed a better-safe-than-sorry approach. They opted out of thimerosal in the remote chance that it was harmful, reasoning that there was little harm in being overly cautious. Unfortunately, the destructive and now discredited ex-Dr Andrew Wakefield confused the issue by releasing a study supposedly establishing a link between the measles-mumps-rubella (MMR) vaccine and autism. To the conspiracy-minded, the timing was too good to ignore: of course the FDA knew that vaccines cause autism; that’s why they rushed to eliminate thimerosal. By the time the dust settled on the Wakefield scandal, the damage was done. Too many parents still refuse important vaccines for their children in the mistaken belief that they pose a health risk. Subsequently, dangerous diseases that were once under control are making a roaring comeback.

Fluoride is poison and it will give you cancer and kill you and cause dental fluorosis.

It tickles me that dental fluorosis is thrown in almost as an afterthought. Fluoride will kill you…and your teeth will be ugly at your funeral!

At any rate, I’ve written about the “dangers” of fluoride before. To summarize: the fluoride levels in toothpaste and drinking water are far below dangerous levels. You would have to gobble down many tubes of toothpaste (at once) before you stood a better-than-average chance of being harmed by fluoride. There is no credible evidence to suggest that our health is being jeopardized by the fluoride we regularly consume. Warnings on toothpaste tubes are put there to protect the companies, not because their product is actually dangerous.

So that’s it. This meme was a whole lot of nonsense, but I think we’ve gained a valuable insight into the mind of its author. The author hates and distrusts the medical establishment and the government, and is willing to accept anything as long as it confirms his beliefs. Let’s consider this a cautionary tale…not of the evils of Big Government, but of the evils of uncritical thinking.
