Flawed Swedish Anti-Vaccine Article Rejected and Retracted

Anti-vaccine post

Anti-vaccine activists allegedly failed to get an opinion piece dishonestly titled “Our children should not be forcibly vaccinated” published in a major Swedish newspaper called Dagens Nyheter. The provided reason was supposedly that it did not include sufficient sources for their anti-vaccine claims. They attempted to publish it on the debate section on the website of the newspaper, but it was retracted a short while after. They will likely play the martyr card and claim that the mainstream media is oppressing them, even though the newspaper just declined publication and retracted a pseudoscientific opinion piece that promoted many scientific falsehoods.

The letter to the editor was published (webcite) a day later on the alternative news website Newsvoice that have supported many different conspiracy theories before. Although many of the claims made have been disproved thousands of times before, it is important to provide credible scientific information in a time where dangerous pseudoscientific myths are gaining ground and so this post will serve a point-by-point refutation.

It turns out that the authors of the opinion piece (Boo, Tips, Ahlm, Karlström och Zazzio) based their case on confusing mandatory with compulsory, butchering a quote from the Sweden National Board of Health and Welfare, spreading fear and uncertainty about vaccine safety and efficacy, claimed that knowledge about the prevalence of vaccine side-effects relies only on spontaneous reporting rather than active monitoring. Finally, they are betrayed by their own ignorance on why infants are vaccinated and even go so far as to propose that vaccines constitute “premeditated attempted murder”.

Mandatory vaccination is not the same as compulsory vaccination

At its core, Boo and co-authors confuses mandatory with compulsory in an effort to spread fear and doubt about vaccines. If something is mandatory, you pay a societal cost for not doing it. For instance, if you fail to show up for a mandatory lab session in a university chemistry course, you will not pass the course or you may not be able to send your child to your favorite candidate school if they require children to be vaccinated. If something is compulsory, on the other hand, it means that things something will be carried out under the threat of violence. If you fail to show up to a compulsory police interrogation, the police will come to your home or job and ask you to come with them. If you decline, you will be put in handcuffs and taken to the police station. If you resist, they will use violence against you.

Mandatory vaccination is not the same as compulsory vaccination. Compulsory vaccination was tried in e. g. the 1800s, and it arguably did not work. That is why countries like Sweden and the United States do not have compulsory vaccination.

Serious side-effects are very, very rare

The CDC has a lot of information about possible side-effects. For the MMR and DTaP vaccines, there is a 1 in 1 million risk of a severe allergic reaction. Other reported side-effects are so rare that if they are real, they cannot be reliably measured (risk much less than 1 in 1 million).

The risk from getting the disease is much worse. The risk of death for diphtheria is 5-10% and for tetanus it is about 10%. For measles it is 2%. Other complications of measles disease is brain inflammation, pneumonia, seizures and several others.

If you compare the risk with the vaccine versus the risk of the disease, the disease is much, much worse.

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, 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 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 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).
