Since most of those who caught the disease were vaccinated with the MMR vaccine, which protects against measles, mumps, and rubella, the anti-vaccine interwebs are jumping up and down pointing at the pro-science people and saying, “neener neener, vaccines don’t work.” Yeah, they’re that immature. And they are absolutely wrong.
Let’s take a look at the whole story, including some very simple math, which even science deniers should understand. Then we can thoroughly debunk the tropes pushed by the vaccine deniers. This should be fun.
There are many canards propagated by the vaccine deniers to support their personal beliefs (really, denialism) about the safety and effectiveness of vaccines. One of their more popular beliefs is that vaccines didn’t end many of the deadly diseases, but improved sanitation, healthcare, nutrition or magical fairies (also known as homeopathy) ended these diseases.
There is even a subgroup of these believers who think that the CDC, historians, and everyone else is lying about the epidemics that existed prior to vaccinations–let’s call this group history deniers. They reject the scientific and historical evidence that vaccines saved lives – amazing.
Yesterday, I posted an article about the recent mumps outbreak in the National Hockey League, which has hit 13 players (there’s no official number, it varies depending on the source) including one of top stars of the league, Sidney Crosby of the Pittsburgh Penguins. A fourteenth player, also on the Pittsburgh team, may also have the virus, depending on the test results that come back for Pittsburgh Penguins winger Beau Bennett, who has been “put in isolation” by the team.
If this outbreak happened in the general American population, it would get some local news, but since there are just a few hundred cases of mumps in the USA in any given year, not many of us would be writing about it. But since it’s happening in a popular sport (technically the fourth most popular sport in the USA, but number 1 in Canada), it gets more focus.
I get to do a click-bait article talking about Sidney Crosby, of the Pittsburgh Penguins, one of the most talented and exciting young ice hockey players in the National Hockey League (NHL), the top level of ice hockey in North America (if not the world). It’s a sport dominated by Canadians, Russians, Czechs, Finns, Swedes, and Americans, though there are a smattering of players from other countries especially in Central/Northern Europe. In Canada, hockey is a religion.
And I love hockey. Yes, I know it’s a sport whose fans are located in freezing cold parts of the world, and has absolutely 0 interest outside of maybe 10 countries. But it’s a truly world sport, with players from all kinds of countries. I sat a game last year where a whole row of fans travelled from Finland to the USA to watch one player. They chatted with other fans, used iPhones (poor Nokia) to text photos to their friends back in Helsinki, and complained about US beers. You don’t get that at a American football or baseball game.
Despite the continued social network misinformation about vaccine safety and/or effectiveness, the United States Centers for Disease Control and Prevention (CDC) has reported that the median vaccination coverage, amongst children between the age of 19-35 months was 94.7% for 2 doses of measles, mumps, and rubella (MMR) vaccine; 95.0% for varying local requirements for diphtheria, tetanus toxoid, and acellular pertussis (DTaP) vaccine; and 93.3% for 2 doses of varicella vaccine among those states with a 2-dose requirement.
The median total exemption rate was 1.8%, a difficult number to truly analyze. The CDC reported many issues like some parents get an exemption even after their children are fully or partially vaccinated, some exemptions are used as a matter of convenience because the parents forgot to vaccinated, and some states don’t report exemptions. Moreover, the CDC data indicates up to 15% of exemptions are “medical,” meaning that a child cannot receive a vaccine as a result of an establish medical contraindication.
The research also shows that there have been no statistically significant changes in either vaccination or exemption rate from 2012-13. This is more statistical support that the antivaccination agenda is not gaining much traction across most of the USA.
In a previous article, from our vaccine legal expert, Dorit Reiss, we learned that there’s a whistleblower lawsuit against Merck regarding the possibility that the company may have engaged in some inappropriate actions in determining the effectiveness of the MMR vaccine (for mumps, measles and rubella), specifically the mumps component of the vaccine. As Reiss stated, despite the suit (and recent ruling which just whether the case could go forward) being a boon to the antivaccination crowd, so far no facts have actually been presented.
In essence, the whistleblowers claim that Merck, the manufacturer of the MMR vaccine, through either direct falsification or poor study design, may have overstated the effectiveness of the mumps component of the vaccine. Merck had been claiming that the vaccine was approximately 95% effective (meaning at least 95% of children given the vaccine were protected against the disease).
So let’s be clear about this so-called whistleblower lawsuit–no evidence has been presented, and that evidence hasn’t been cross-examined. And one more thing–courts do not decide science, it’s not their role. Science is not a debate, it is a cold evaluation of evidence. And in science, the weight of the evidence is both in quality and quantity. Unless you’re a complete anti-science cult member, whatever this court decides, whatever malfeasance was practiced by Merck, whatever the whistleblowers have to say, the scientific evidence tells us that the mumps vaccine component is highly effective and extremely safe.

A few days ago, I wrote an article discussing how antivaccination trope inventors could not understand the most basic elements of mathematics in reading a vaccine label. They misinterpreted some simple math like that the toxic level of a substance is several million times higher than what is injected. I suppose in the minds of vaccine deniers, 1=1 billion. Or 1 trillion. Or 4783.2226. It just depends.
And if they can’t understand the simplest of math principles, assuming that they would understand population level statistics might be a really bad assumption.
Even though the vaccine deniers champion the trope that these diseases are “not serious,” real evidence from real infectious disease medical specialists say otherwise. Measles, mumps and rubella can be dangerous diseases with debilitating complications, including death, for both children and adults. And as you can see in the map (click on it for greater detail), outbreaks of measles (in red), mumps (in olive) and rubella (in blue) are larger than it should be in both the developed and the developing world than it should be, given the easy access to the MMR (or MMRV) vaccines.

For New Year’s Day, I’m republishing the top 10 articles I wrote in 2013. Well, actually top 9, plus 1 from 2012 that just keeps going.
#10. This article was published on 3 December 2013, and has had over 5000 views. It’s one of my favorite because it shows, with scientific evidence, that the trope pushed by the vaccine deniers that better sanitation, food, and medicine reduced the mortality from these diseases. But we know it’s the vaccines, and we have brilliant science to support that fact.
One of the tropes of the antivaccination world is that vaccines didn’t stop diseases. They give credit to everything from modern medicine to better food to better sanitation. Some of the credit they give is ironic since many vaccine deniers hate most aspects of modern medicine and believe that food was better 100 years ago. You can never get enough of the contradictions and hypocrisy of the antivaccine crowd.
I think it becomes easy to dismiss the value of vaccines in ending widespread disease because almost anyone writing today about vaccines has no memory of ubiquitous and deadly epidemics of diseases. We’re almost at a point in our culture that if Twitter doesn’t report it, it didn’t happen, so infectious diseases are something that happened back when humans lived in caves, prior to the advent of social media. I happen to have been born right near the end of widespread epidemics of infectious diseases, so I don’t remember any epidemics personally, though I recall a few classmates in high school who had a few effects from polio and other diseases. Culturally, we have forgotten our past with respect to diseases. Continue reading “Why we vaccinate–103 million cases of diseases averted since 1924”
Current studies do not support the hypothesis that multiple vaccines overwhelm, weaken, or “use up” the immune system. On the contrary, young infants have an enormous capacity to respond to multiple vaccines, as well as to the many other challenges present in the environment. By providing protection against a number of bacterial and viral pathogens, vaccines prevent the “weakening” of the immune system and consequent secondary bacterial infections occasionally caused by natural infection.
