Debunking “The Pro-Vax Argument Lost Me When”

16 anti-vax claims debunked

Credible scientific and medical information about vaccines can be gotten from reading the websites of medical organizations and government public health websites, science and medicine textbooks by mainstream publishers and reading scientific review papers in highly credible scientific journals. The material found therein has very often been fact-checked and subjected to peer-review by other experts. Although certainly not infallible, together they represent the best information currently available.

Anti-vaccine activists, on the other hand, primarily rely on misleading information found on conspiracy blogs, YouTube videos and Facebook groups. These are not credible sources. One such blog post that is circulating in anti-vaccine communities is called The Pro-Vax Argument Lost Me When (with the subtitle “They Couldn’t Answer These Questions”) and feature 16 anti-vaccine claims disguised as superficially innocent questions for which the writer wrongly believes science has no answers.

In reality, this is a common denialist tactic called “just asking questions” (or JAQing off) that is based on making overt pseudoscientific claims, but hiding behind the trope that they are “just asking disturbing questions” in an effort to evade scientific objections. The blog post is written anonymously and contains no references to the scientific literature whatsoever. Despite this, it has achieved considerable spread across social media. So without further ado, here are scientific answers to all “questions” asked, backed up by real scientific references. Read more of this post

17 Great Science and Skepticism Things in 2016


Many people consider 2016 to be a truly shit year with the election of Donald Trump, Brexit, continued armed conflicts in the world, terror attacks and famous celebrities dying. While the overall trend shows great improvement on just about any metric, it is not impossible for individual years to deviate somewhat from this trend. Thus, we should not lose too much hope because of events that happened during this year. For those of you who are feeling the 2016 blues, try reading this Vox article that feature Steven Pinker explaining how 2016 has made improvements in many areas.

However, let us focus a bit on some of the positive and upbeat events during 2016 that related to science, skepticism or related issues. Ebola is over in Africa and we now have a vaccine. The Paris Agreement was signed and the ozone hole over the Arctic show signs of healing. Sri Lanka is free of malaria and the Americans are free of measles. Gravitational waves were discovered and a new record-breaking small genome was synthesized. The FTC cracked down on homeopathy and the Swedish government will transition towards eliminate special treatment as well. Here are 17 good things that happened in 2016.

When Anti-Vaccine Activists Falsely Dismiss Polio and Measles Harm

Vaccine Outliers

Russell Blaylock is a brain surgeon, but also a proponent of a whole host of misguided pseudoscientific claims about aspartame, MSG, water fluoridation, vaccines, medications for high cholesterol and he also believes in chemtrails. He even goes so far as to argue that modern medicine is not in the business of preventing disease, only treating it with expensive medications, despite the fact that vaccines are the pinnacle of preventative medicine and are very cheap compared with treatments for e. g. chronic diseases.

A long quote attributed to Blaylock is being circulated on social media originating from a website called “Vaccines by the Outliers”. The name refers to a closed Facebook group with over 5000 members. They call themselves “vaccine education and awareness group”, but readily admit that they consider that “much of what is heard about vaccines and vaccination within the mainstream, corporate media, the government, the medical profession, and certainly within the vaccine manufacturing industry is not the whole truth, and in many cases is just plain false.”

In reality, Blaylock borders on germ theory denialism, systematically attempts to dismiss the dangers with measles and polio, ignores the realities of importing vaccine-preventable diseases by travel, makes a common mistake of conflating death rates with incidence data, claims better sanitation got rid of measles and polio, despite the fact that this occurred in different decades, claims polio is a harmless summer flu and that vaccines overwhelm the immune system. More infuriating, he attempts to falsely tie the horrible tragedy of malnourished children dying to vaccines without any evidence whatsoever.

The Scientific Ignorance of Stasia Bliss – Part X: Measles

Note: This is the tenth and final installment in an article series debunking the massive amount of pseudoscientific claims made by Stasia Bliss. This post will slash through her false claims about the MMR vaccine and measles. For more posts in this series, see the introduction post here.

Bliss on measles

We have now reached the final part in this series on the pseudoscientific nonsense promoted by model and freelance writer Stasia Bliss (who calls herself a “master alchemist” and “a High Priestess of Qi Vesta”). In previous installments, several of her claims have been refuted, such as her claim that individuals with cystic fibrosis caused their own disease by eating acidic food and thinking negative thoughts, that colon cleansing and hydrochloric acid supplements are effective against HIV/AIDS, that staring into the sun for long periods of time allows for astral projection and unaided human flight, that DNA has twelve strands, that a vital life force exists, that eating genetically modified foods makes you less humans, that dark matter does not exist, her promotion of quantum woo and her belief in human shape-shifting and death as the result of a psychological conditioning.

In this tenth and final part, the claims made by Bliss with regards to measles and the MMR vaccine will be critically examined. Despite her beliefs, measles is a dangerous disease and not a “natural cleansing” or “adventure” and the MMR vaccine is safe and effective. Her misguided reliance on the National Vaccine Information Center (a pseudoscientific anti-vaccine organization) and VAERS dumpster-diving will be exposed. Contrary to Bliss, the Vaccine Court provides individuals who have experienced genuine adverse events from vaccines with compensations in a way that is easy, cheap and fast for those individuals. Like many other anti-vaccine activists, Bliss has difficulty grasping the concept of herd immunity. Her promotion of quack treatments (that lack evidence of efficacy) is based on a misunderstanding of physiology and evolution. She even goes so far as to claim that childhood diseases are a result of too much “toxins” from modern life (thereby embracing germ theory denialism), apparently not understanding that measles existed many hundreds of years before present and the fact that the body has robust systems for elimination actual toxins from the body.

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).
