Gardasil safety and efficacy – debunking the HPV vaccine myths

Gardasil safety and efficacy

There was an article published in Pediatrics that described how educating either teenagers or their parents about HPV vaccinations had little effect on the overall vaccination rate for the vaccine. Essentially, the researchers found that it was a 50:50 probability that any teen would get the vaccine, regardless of their knowledge of HPV and the vaccine itself. Some of the reasons why the HPV vaccine uptake is so low is a result of several myths about Gardasil safety and efficacy.

So I thought about why that Pediatrics study found that education about HPV and Gardasil didn’t move the needle on vaccination uptake. It’s possible that the benefits of the vaccine is overwhelmed by two factors–first, that there’s a disconnect between personal activities today vs. a disease that may or may not show up 20-30 years from now; and second, that the invented concerns about the HPV quadrivalent vaccine, promulgated by the usual suspects in the antivaccination world, makes people think that there is a clear risk from the vaccine which is not balanced by preventing cancer decades from now. It’s frustrating. Continue reading “Gardasil safety and efficacy – debunking the HPV vaccine myths”

HPV vaccine safety – another massive scientific study (UPDATED)

HPV vaccine safety

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.

HPV vaccine propaganda – anti-vaxxers get it all wrong again

HPV vaccine propaganda

Although I don’t have official evidence, I think that anti-HPV vaccine propaganda is a special subset of the anti-vaccine disinformation effort. I think that the most outrageous claims about vaccines are often made about HPV anti-cancer vaccine.

But the anti-HPV vaccine propaganda hit a whole new high (no, wait, it’s a low) when an anti-vaccine group on Facebook produced what they claim is an “accurate” HPV vaccine commercial.

I couldn’t let this disinformation about a cancer prevention vaccine pass. So here we go. Continue reading “HPV vaccine propaganda – anti-vaxxers get it all wrong again”

HPV vaccine and autoimmune diseases – no link in new 2 million patient study

HPV vaccine and autoimmune diseases

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.

Japan bans Gardasil – debunking myths about the HPV vaccine

Japan bans Gardasil

One of the most popular zombie memes and tropes of the anti-vaccination movement is that Japan bans Gardasil – oh noes! Of course, like a lot of the junk information passed along by the anti-vaccine crowd, it’s completely false, unless you’re willing to take anything they say on faith.

There are a couple of consistent trends in the anti-vaccine movement. They claim that vaccines cause autism (disproved with the highest quality of evidence); and they maintain that the HPV vaccines cause all kinds of harm to teens and young adults. And there are literally mountains of data derived from numerous huge epidemiological studies that the Gardasil cancer preventing vaccine is one of the safest vaccines on the market (and that’s a high bar to exceed, given the high safety profiles of all vaccines).

So if you really want to prevent cancer, one of the best ways available to you is getting the HPV vaccine. The idea is so simple, yet is clouded by the myths about HPV vaccines – one of the most popular, of course, is that Japan bans Gardasil. Let’s examine this fable with a critical and skeptical eye.

The tl;dr version – Japan did no such thing.

HPV vaccine safety study – biased, poor design and results

HPV vaccine safety study

If you want to read a quality HPV vaccine safety study, I can point to numerous high quality, unbiased, well-designed epidemiological studies that show that HPV vaccines are safe and very effective.

Here’s a review of a study of 200,000 subjects.

Here’s a review of a study with over 1,000,000 subjects.

Here’s a review of a study with over 2,000,000 subjects.

If you want to give us a new HPV vaccine safety study, it better have large numbers (to identify small differences in risks), be unbiased, and use some sort of control group.

Genevieve Rail – “lead developer” of HPV vaccines opposes it

Genevieve Rail

Here we go again. We recently wrote about Diane Harper, another “lead developer” of the HPV vaccines, who has a rather complicated view on HPV vaccines. She makes disparaging remarks about the vaccine, yet her peer reviewed publications are generally favorable to the HPV vaccine. Genevieve Rail, a kinesiology researcher at Concordia University in Montreal, Quebec, Canada is the next one being pushed by anti-vaccine activists.

Outrageous claims are made about Genevieve Rail’s expertise with HPV vaccines, like Gardasil. And she helps with the claims by making outlandish comments about the vaccine:

“I’m sort of raising a red flag, out of respect for what I’ve found in my own study, and for the despair of parents who had totally perfect 12-year-olds who are now in their beds, too tired to go to school. Yes, we’re going against the grain, and we are going against those who are believed, i.e. doctors and nurses and people in public health.”

So here we go again, another darling of the anti-vaccine world. Time to look into who Genevieve Rail is. And does she have any standing in the scientific knowledge about the HPV vaccine. Continue reading “Genevieve Rail – “lead developer” of HPV vaccines opposes it”

Diane Harper supports HPV vaccine – and she published it

diane harper

A few years ago, Dr. Diane Harper was the darling of the anti-vaccine world, for two reasons. First, she was one of the researchers who performed clinical trials for Gardasil. And second, she appeared to be against HPV vaccines, specifically Gardasil.

But the story was much more nuanced.  I argued that her publication record presented a much different picture – she actually supported the vaccine. But typical of the zombie memes and tropes of the anti-vaccine world, every few months it’s breathless reported that Dr. Harper is opposed to Gardasil.

Recently, she published another article about HPV vaccines, and if there’s any doubt that she is in favor of HPV vaccines, that is gone. But that probably won’t stop the anti-vaccine crowd.

HPV vaccine side effects – unrelated to chronic fatigue syndrome

HPV vaccine side effects

The list of HPV vaccine side effects is long and, on the surface, very troubling. But study after study, some of them with millions of patients, have found that the vaccine is extremely safe, and the side effects attributed to the vaccine occur at the same rate between vaccinated and unvaccinated individuals.

Now, there is a large new study in Norway that examined another hypothetical side effect that has been claimed to be associated with the HPV vaccine. And what did the study find? No link.

We’re going to examine the new study on potential HPV vaccine side effects, which will tell us more about the safety of the vaccine. Continue reading “HPV vaccine side effects – unrelated to chronic fatigue syndrome”

HPV and prostate cancer – meta-analysis shows link

HPV and prostate cancer

It has been well established that human papilloma virus (HPV) is closely linked to numerous cancers. Recently, evidence has been uncovered that show a link between HPV and prostate cancer. This provides us with more evidence that preventing these infections with the HPV vaccine can lead to a reduction in many types of cancers in both men and women.
