A Swedish Vaccine Rejectionist Comes Out to Play…

…but gets badly burned by powerful radiance of science-based medicine and reason.

Note: In a response to an earlier article where I debunked a Swedish anti-vaccine crank by the name of Marina Ahlm, she posted a comment so scientifically flawed that I thought I dissect it in detail. However, my comment became so long that it was worth its own blog entry. I have reproduced my reply below. Enjoy!

I see that Marina Ahlm found her way to my refutation of her blog post. She seems very keen on commenting, as she submitted her comment multiple times. It is interesting to see that she have merely senselessly copy/pasted the comment word-for-word from other texts on the internet, often repeating the same flawed claims that she presented in the original entry at your anti-vaccine blog, rather than making arguments in her own words. she also did not respond to any of the points that I made in this blog entry. Did she even read it before commenting? If she read the comment policy of this blog before she posted (she clearly did not), she would have seen that it prohibits copy/pasting long arguments without any original input. However, I will be humble and allow this behavior. For now. Also, unlike what goes on at the anti-vaccine blog at vaccine.me, I do not randomly delete comments or edit them to undermine critics. She and her allies have been exposed.

Anyhow, I will indulge her delusional beliefs and provide a point-by-point refutation (again!). Hopefully she will learn this time around, but I doubt it. When someone is so ideologically committed as she is, it is extremely hard to make them see their error. She more or less repeat the same logical fallacies as before: confirmation bias (she artificially inflates minor setbacks and limitations with vaccines while ignoring the benefits and efficacy), perfect solution fallacy (she reject vaccines because they are not perfect) and she also tend to quote government reports and scientific articles out of context. Probably, she have not read the original documents, but merely copy/paste what other anti-vaccine cranks have written Read more of this post

The Insanity that is Swedish Anti-Vaccine Crankery

Sweden has largely been spared of the creeping vaccine rejectionist propaganda that has plagued the United States and Great Brittan for decades. However, the anti-vaccine forces are stirring under the surface and have acquired a larger internet presence than ever before, especially after the vaccination program against the pandemic H1N1/09 virus. The growing movement is centered around conspiracy-mongering websites like vaken.se that has bought into almost every conspiracy theory imaginable about 9/11, water fluoridation, vaccines, global warming and genetically modified foods. Another important hub of the Swedish anti-vaccine movement is Annika Dahlqvist, who is a medical doctor promoting diet as protection against infectious diseases. For her pseudoscientific claims, she was awarded denialist of the year (“Årets förvillare”) by a Swedish skeptic society (called “Föreningen för vetenskap och folkbildning”) in 2009. A third central figure is blogger Linda Karlström (an economist), who has recently started a new anti-vaccine group blog under the domain vaccin.me. She has teamed up with others and they spend most of their time shamelessly parroting the anti-vaccine falsehoods put forward people like Mike Adams, Lawrence B. Palevsky and Jackie Swartz, a anthroposophist doctor at a Swedish CAM clinic called Vidarekliniken. Karlström’s group is collecting anecdotal stories from anti-vaccine parents who believe their children have gotten hurt by vaccines. According to their website, they intend to gather 1000 reports before they attempt at class-action lawsuit.

Luckily, they do not have free reign. Responsible science journalists, scientists, public health professionals as well as the skeptic society of Sweden are combating their falsehoods, both online and offline.

Let us take a detailed look at what passes for evidential arguments at Karlström’s blog. The blog post that I am refuting is written in Swedish, but I will translate the claims being made to the best of my ability. Feel free to use online translation services to check the translation. The user Marina Ahlm (a nurse currently trying to become a “medicinal foot therapist” according to the website bio) posted an entry absurdly entitled Herd immunity cannot be achieved through vaccination: even vaccinated people carry viruses and bacteria that can be found here. As we shall see, it is filled by distortions, scientific falsehoods, half-truths and plain old nonsense.

Measles vaccination has been a scientific success!

—> According to the WHO (2011), the measles mortality has been reduced by as much as 78% between 2000 and 2008 mostly due to the benefits of large-scale immunization program. In the vast majority of regions, this figure is at 90% (between 2000 and 2010).

—> After the introduction of the measles vaccine in 1963, the incidence of measles fell dramatically, from almost 500000 cases per year to almost none in comparison. Even though small and sporadic peaks and valleys due to natural fluctuations, the huge reduction is real (CDC, 2011). To be sure, the fact that B follows A does not mean that A causes B, but when you have a strong correlation plus a mechanism that is supported by many different lines of evidence, the reasonable position is to tentatively accept the efficacy of the measles vaccine.

—> Ahlm makes the flawed argument that since, apparently, it is practically difficult to evaluate the efficacy of a second dose of measles vaccine, this means that the measles vaccine has been a failure and that WHO only offers excuses. However, practical problems evaluating the efficacy of a second dose of measles vaccines compared to getting one cannot undermine the enormous mountain for the efficacy of the measles vaccine. As far as we know, a single dose may potentially offer the bulk of the protection.

—> In fact, the WHO does not offer excuses, but points out the real reasons why we have seen some resurgence of measles in certain areas of the world: vaccine efforts are sometimes not sustained partly because of the actions of vaccine rejectionists (like Ahlm): “However, global immunization experts warn of a resurgence in measles deaths if vaccination efforts are not sustained. Experts fear the combined effect of decreased political and financial commitment could result in an estimated 1.7 million measles-related deaths between 2010-13, with more than half a million deaths in 2013 alone” (WHO, 2011a).
