I do repeat myself repeatedly, I admit, especially about cancer. There are really only a handful of ways to lower your risk of cancer – stop smoking, stay out of the sun, eat a “healthy” diet, keep a healthy weight, don’t drink alcohol, and a few other things. One of those few science-based methods to stave off cancer is getting vaccinated against cancer-causing viruses. The HPV vaccine and hepatitis B vaccine (see Note 1) are some of the most powerful tools in cancer prevention.
The Centers for Disease Control and Prevention (CDC) have published a detailed report of HPV-related cancers in the USA, and it states that there are over 41,000 HPV-related cancers diagnosed every year. The National Cancer Institute categorizes “common cancers” as those with over 40,000 new cases a year – if we could lump all of these HPV-related cancers into one group, it would be considered a common cancer, contradicting the anti-vaccine memes that HPV isn’t that dangerous.
And the HPV vaccine could prevent most of those cancers by blocking the HPV types that cause those cancers. Continue reading “HPV vaccine could prevent 41,000 cancers a year – Gardasil works”
If you have any interest in HPV vaccines, you’ve probably heard about Diane Harper, who the anti-vaccine religion claims was a “lead Gardasil researcher” who came out against the vaccine. Many of us were never convinced that she was really anti-vaccine, although she seemed to have vacillating views on the HPV vaccine depending on a variety of random factors, including who was feting her at any particular point in time.
Dr. Harper was a frustrating character in the conversations about the HPV vaccine. Although some (but certainly not all) of her comments about the vaccine could be construed as an anti-HPV vaccine, her publications, and many other public comments, seemed to clearly show that she was a supporter of the vaccine.
A few writers in the scientific skeptic blogosphere have contacted her, either in person or through interviews, and most have come away with the impression that she was solidly in support of the vaccine. However, and I have no evidence of this whatsoever, she always seemed to be biased against Gardasil, manufactured by Merck, so maybe she had some personal vendetta. We will probably never know, I suppose.
But a recent announcement should put an end to the Diane Harper anti-Gardasil meme – well I’m more cynical than that, I know the vaccine denier mob will keep bringing it back like a zombie. So, let’s take a look at Dr. Harper and her announcement. No one should be surprised. Continue reading “Diane Harper, star of anti-vaccine memes, supports HPV vaccines”
I thought I had read it all, but here comes one out of recesses of the anti-vaccine mind – where logic and science disappear into a black hole. This time, an economist, with absolutely no background in science, writes a lame article that claims that the HPV vaccine affects pregnancy rate. Somehow, because of reasons, unknown to modern science.
The anti-vaccine religion definitely hates the HPV vaccine more than any other one out there. They invent more lies about it while ignoring the overwhelming scientific consensus about the vaccine’s safety and effectiveness. But relying upon facts is generally not something found in the anti-vaccine wheelhouse.
Of course, the false claims about the HPV vaccine often rely upon pseudoscience produced by anti-vaccine shills like the oft-retracted Shaw and Tomljenovic, the infamous Lyons-Weiler, and the preposterous Shoenfeld. Because the anti-vaxxers lack any evidence to support their dislike of the HPV vaccine, they require the appeal to false authority to claim that these discredited pseudoscientists’ work is somehow more important than all of the body evidence, from real, respected scientists, that supports HPV vaccine safety and effectiveness.
So, let’s take a look at this new study from a non-scientist claiming that the HPV vaccine affects pregnancy rates. I almost thought about ignoring it, but it’s just too funny. Continue reading “HPV vaccine affects pregnancy rate – laughable anti-vaxxer study”
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.

Despite the cancer tropes that seem to afflict Facebook and Twitter these days, which includes the laughable “Big Pharma is hiding a secret cancer cure” myth, recently published evidence shows that cancer mortality rates in the USA are dropping. This is great news if you’re wondering if cancer is an end-of-life diagnosis – science-based medicine is attacking and beating cancer with numerous strategies for each cancer. And yes, instead of hiding cancer cures, Big Pharma is providing a lot of the successful medications in treating the disease.
The report, published in the journal Cancer by researchers at the American Cancer Society, the Centers for Disease Control and Prevention, the National Cancer Institute, and the North American Association of Central Cancer Registries, provides us with the mostly good news. Cancer mortality rates, which describes the number of cancer deaths per 100,000 people per year, have dropped significantly in the USA. This drop includes most of the common cancers, such as lung, colorectal, breast, and prostate.
Unfortunately, the news isn’t all good – some cancer mortality rates have increased, and I will try to explain why. Let’s take a look at cancer and this new paper. Continue reading “Cancer mortality rates – mostly great news in war on cancer”
The HPV cancer-preventing vaccine, especially Gardasil (or Silgard, depending on market), has been targeted by the anti-vaccine religion more than just about any other vaccine being used these days. So many people tell me that they give their children all the vaccines, but refuse to give them the HPV vaccine based on rumor and innuendo on the internet. This article provides all the posts I’ve written about Gardasil safety and efficacy.
As many of regular readers know, I focus on just a few topics in medicine, with my two favorites being vaccines and cancer – of course, the Gardasil cancer-preventing vaccine combines my two favorite topics. Here’s one thing that has become clear to me – there are no magical cancer prevention schemes. You are not going to prevent any of the 200 different cancers by drinking a banana-kale-quinoa smoothie every day. The best ways to prevent cancer are to quit smoking, stay out of the sun, keep active and thin, get your cancer-preventing vaccines, and following just a few more recommendations.
The benefits of the vaccine are often overlooked as a result of two possible factors – first, there’s a disconnect between personal activities today and cancer that could be diagnosed 20-30 years from now; and second, people think that there are significant dangers from the vaccine which are promulgated by the anti-vaccine religion.
It’s frustrating and difficult to explain Gardasil safety and efficacy as a result of the myths about safety and long-term efficacy of the vaccine. That’s why I have written nearly 200 articles about Gardasil safety and efficacy, along with debunking some ridiculous myths about the cancer-preventing vaccine. This article serves to be a quick source with links to most of those 200 articles.
And if you read nothing else in this review of Gardasil, read the section entitled “Gardasil safety and effectiveness – a quick primer” – that will link you to two quick to read articles that summarize the best evidence in support of the vaccine’s safety and effectiveness.

One of the enduring myths (there are so many) about the HPV vaccine is that it is linked to one or more autoimmune syndromes, an abnormal immune response to a healthy body part. These claims, pushed by an Israeli physician, Yehuda Shoenfeld, are called “autoimmune syndrome induced by adjuvants (ASIA)” and, sometimes, Shoenfeld’s Syndrome.
Of course, ASIA is not accepted by the scientific and medical community (and see this published article), was rejected by the United States vaccine court as a claim for vaccine injury, and should not be accepted by parents deciding whether they should vaccinate their children. Furthermore, the European Medicines Agency, which is the primary regulatory body in the EU for pharmaceuticals, has rejected any link between the HPV vaccine and various autoimmune disorders. The science stands in direct opposition to autoimmune syndromes being caused by any vaccine.
Despite the lack of evidence supporting the existence of autoimmune syndrome induced by adjuvants, and even more powerful evidence that it doesn’t exist, the anti-vaccine religion still cherry-picks articles to support their preconceived conclusions that the HPV cancer-preventing vaccine is dangerous. Continue reading “Autoimmune syndromes induced by adjuvants – another anti-vaccine myth”
Stop me if you’ve heard this before – another anti-HPV vaccine paper gets retracted. Yeah, I’ve written about these retractions so many times (here, here, and here, and that’s just a sample), I could publish a book just about these “researchers.” And now we here about another anti-vaccine study, that was recently retracted, which claimed that the HPV vaccine caused neurological damages. This study heads to the dustbin of scientific research, as it deserves.
A mountain of high quality, robust clinical and epidemiological evidence has overwhelmingly established that the HPV vaccine is safe and effective. This is approaching the level of settled science.
With the retraction of the study that the HPV vaccine caused neurological damage, it’s clear that the anti-vaccine crowd has almost nothing to support their hatred of the vaccine. Not that it will stop them. Continue reading “HPV vaccine caused neurological damage? Journal retracts article”
One of the many tropes about HPV vaccine from the anti-vaccine religion is that the vaccine has no effect on any cancer. Recently, I wrote an article that outlined the evidence that supports a link between HPV vaccines and cancer – that is, the vaccine does lower the risk of cancer. After I wrote that article, a new systematic review was published that, indeed, the HPV vaccine prevents cervical cancer.
Many people think that cancer is some sort of on/off switch – in fact, HPV-related cancers may take years or decades to be diagnosed. However, it’s been 8-12 years since the vaccine has been available (depending on the country), so a population of young women (the vaccine was only indicated for women in most countries until a few years ago) is now getting to the age where they may be diagnosed with either cancer or pre-cancerous lesions.
As the population of women (and eventually men) reaches the age where risks of certain cancers are increased, we can use epidemiological studies to determine whether or not there is a difference in cancer risk between vaccinated and unvaccinated groups. Let’s review the systematic review that examined a surprisingly large number of studies that support the fact that the HPV vaccine prevents cervical cancer.

The history of one fake anti-vaccine researcher after another permeates the anti-vaccine religion – it is legendary. We have the multiple-retracted authors, Shaw and Tomljenovic who think that the HPV vaccine is dangerous. They keep pushing this trope, but they really present no clinical evidence to support their beliefs, and they are mocked mercilessly for their poor science. And then their fake research is retracted.
Now there’s a new paper being pushed by the anti-vaccine world published online in the Indian Journal of Medical Ethics. which pushes the implausible narrative that a review of cervical cancer incidence in Sweden shows that HPV vaccine increases the risk of cancer. We will get to a discussion of the data in a bit, let’s look at the big issue with paper – the author himself.
