A clinical trial that examined the potential of the bacillus Calmette-Guerin vaccine, or BCG vaccine, to reverse even advanced type 1 diabetes mellitus was recently published in a Nature journal. In addition, researchers proposed a possible mechanism describing how the BCG vaccine may enhance the immune system and could stop and reverse the damage that leads to diabetes. But does this constitute evidence that this vaccine can really reverse type 1 diabetes? Spoiler alert – I’m not fully convinced, but my interest is piqued.
The BCG vaccine was initially developed to prevent tuberculosis. It is one of the oldest vaccines available on the market, first used in 1921 (pdf). With the successful eradication of tuberculosis in many countries, the vaccine isn’t used very much anymore, except in countries with endemic tuberculosis.
Let’s take a look at what we know about diabetes, how the BCG vaccine might be able to reverse type 1 diabetes mellitus, and what the new article reports. Continue reading “Reverse type 1 diabetes mellitus with BCG vaccine – promising results”
There are so many outlandish and unsupported claims about the HPV vaccine, it’s difficult to keep up with them all. One of the most outrageous lies about the HPV vaccine is that it causes autoimmune diseases, despite the robust epidemiological or clinical evidence that firmly establishes the safety of the HPV vaccine, especially with respect to autoimmune diseases.
Autoimmune diseases are conditions where the immune system has an abnormal response to normal cells in the body. Celiac disease, type 1 diabetes mellitus, multiple sclerosis, and many other conditions are as a result of an autoimmune disorder. We don’t know what causes the autoimmunity, but there is almost no biological plausibility that any vaccine could induce the disease.
Despite the lack of a reasonable biological mechanism leading from the HPV vaccine to any of the multitudes of autoimmune diseases, the anti-vaccine forces continue to try to establish a link. For example, Yehuda Shoenfeld has pushed a ridiculed hypothesis that the vaccine causes something he calls autoimmune syndrome induced by adjuvants (ASIA). Not a single respected scientist buys into ASIA, and Shoenfeld has presented no vigorous clinical or epidemiological evidence supporting its existence.
Not to pile onto the anti-vaccine tropes about the vaccine, but a large, and new, Canadian study has once again shown us that there are no links between the HPV vaccine and autoimmune diseases. This adds to the body of evidence that, for real science, reinforces the conclusion that the HPV vaccine is an incredibly safe vaccine.

Immune system myths are one of the common claims of the junk medicine crowd, especially the anti-vaccine activists. The pseudoscience of the immune system is pernicious and possibly dangerous.
It’s frustrating that the pseudoscience from the junk medicine crowd claims that this supplement or that food is critical to boosting the immune system – hang out for a day on Facebook, and you’ll probably see way too many memes saying that all you have to do to boost your immune system is eat a blueberry kale smoothie. I still see that dumb banana claim that it cures cancer.
The problem with these immune system myths is that they overlook or ignore a basic physiological fact – the immune system is a complex interconnected network of organs, cells, and molecules that prevent invasion of the body by hundreds of thousands, if not millions of pathogens and other antigens every single day.
And no matter how much individuals try to trivialize the complexity of the immune system, it does not make it so. One can claim all day long that downing a few tablets of echinacea will boost the immune system to prevent colds (it doesn’t), it doesn’t make it scientifically accurate. Nor does it create an accurate description of the immune system.

There are so many anti-vaccine religious tropes about the safety of vaccines, that it is often hard to keep them all straight. One of the current ones is that vaccines cause autoimmune diseases such as multiple sclerosis. Does scientific evidence support the hypothesis that vaccines cause multiple sclerosis?
Well, I have written about whether vaccines cause multiple sclerosis before, and based on the scientific evidence (see here and here), there simply was no link between them. Of course, with the anti-vaccine religion, evidence be damned, they will stand by their claims. All I can do is repeat myself with more and more evidence, refuting their claims.
There is a new review of the evidence of whether vaccines cause multiple sclerosis, and once again, they found nothing. And once again, I will review the evidence to see if there is something to the claims of the anti-vaccine religion. I should give a spoiler alert, but you all know what’s coming.

If you cruise around the internet, engaging with the antivaccination cult (not recommended), you will pick up on their standard tropes, lies, and other anti-science commentaries. One that has always bothered me, not because that it was a lie, but because I had enough evidence floating in my brain that I was wondering if it were true–that vaccines cause diabetes, especially the Type 1 version.
A lot of the vaccine deniers believe that vaccines cause a lot of everything and several claims that vaccines cause Type 1 diabetes (or here), based on little evidence. As far as I can tell, this myth is based on the “research” from J. Barthelow Classen, M.D., who has pushed the idea that vaccines cause type 1 diabetes, through some magical process that has never been supported by other independent evidence.
In another example of the antivaccination world’s cherry picking evidence to support their a priori conclusions, they ignore the utter lack of plausibility supporting any link between vaccines and Type 1 diabetes. At best, Classen has cherry-picked statistics to support his predetermined conclusions, “comparing apples to oranges with health data from different countries, and misrepresenting studies to back his claim.”
Moreover, Classen seems to come to his beliefs based on population-wide correlations that rely on post hoc fallacies, rather than actually showing causality between vaccines and diabetes. It’s like finding that a 5% increase in consumption of Big Macs is correlated with Republican wins in elections. They may happen at the same time, but it would take a laughable series events to show any relationship.

In a 2013 study of over 1 million girls, the overall HPV vaccine safety for teenage girls was reaffirmed. There appear to be no links between serious adverse events and the HPV vaccines. This is in line with numerous other large size epidemiological studies of HPV vaccines.
Let’s take a look at the HPV vaccine safety that is supported by this trial.

The link between HPV vaccine and autoimmune diseases is one of the enduring myths about Gardasil. It is regularly debunked by scientists in large scale case control studies, but that never appears to be enough to silence the critics.
For example, the so-called autoimmune syndrome induced by adjuvants (ASIA) pushed by an Israeli physician, Yehuda Shoenfeld remains a trope that pervades the anti-Gardasil community. Shoenfeld claims that the HPV vaccine is causally linked to various autoimmune syndromes. However, ASIA is not accepted by the scientific and medical community (and see this published article), and was rejected by the United States vaccine court. It should not be used by parents as a reason to reject the HPV vaccine..
Large studies (and this large study) continue to reject links between the HPV vaccine and autoimmune diseases. Now, we’re going to take a look at a recently published article that continues to reject any link.

The HPV vaccine and autoimmune diseases link is one of the enduring myths about the vaccine, which is regularly debunked by scientists everywhere. The so-called autoimmune syndrome induced by adjuvants (ASIA) pushed by an Israeli physician, Yehuda Shoenfeld. He claims that the HPV vaccine are causally linked to various autoimmune syndromes. However, ASIA is not accepted by the scientific and medical community (and see this published article), was rejected by the United States vaccine court, and should not be accepted by parents deciding whether they should vaccinate their children.
And, according to a recent study published in the Journal of Autoimmunity, human papillomavirus (HPV) vaccines do not increase the risk of developing autoimmune diseases (ADs). More evidence that there is no link between the HPV vaccine and autoimmune diseases.

I have frequently stated that the breadth and depth of vaccine research, which provides solid evidence on the safety and effectiveness of vaccines, overwhelms the misinformation, logical fallacies, and conspiracies pushed by the Society for Promotion of Vaccine Preventable Diseases (that is, the antivaccine cult).
In other words, there is so much evidence, published in generally respected, high quality journals, that it is the basis of a pure, 24-karat gold scientific consensus about vaccine safety and effectiveness. Using just one search parameter, vaccines + efficacy + safety, there are over 4200 articles published over the past 55 years on vaccines. Other search parameters show even more results.
As I’ve said time and again, the only thing that matters to science is the quality and quantity of repeated evidence derived from a broad range of different studies. We’ve got that. Continue reading “The breadth and depth of vaccine research”
If you spend time observing the “vaccine debate” (it’s not a debate), you’ll hear every dumb argument to deny science. But one thing that you’ll see repeatedly from the antivaccination cults are that they would support vaccinations if there were better vaccine clinical trial design.
The problem with the cult’s demand for better vaccine clinical trial design is really one of several moving targets for their denialism, relying on a form of the Argument from ignorance, claiming that if we can’t absolutely “prove” that vaccines are safe, then it must be absolutely unsafe.
For example, there are literally thousands of articles, ( an example here and was discussed here), that actually provide overwhelming evidence of the safety and effectiveness of vaccines using real science, real statistics, and real hard work. The antithesis of the fake science, bogus statistics, and 2 hours of Google.
