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 fear, uncertainty, and doubt (FUD) campaign, a disinformation tool used by the anti-vaccine religion for propaganda purposes, against the HPV vaccine would laughable if the lies didn’t put our young people at risk for cancer in the future. We already have circumstantial evidence that the HPV vaccine prevents cancer – but now we’re accumulating robust direct evidence that it can stop HPV-related cancers.
Despite the claims of anti-vaccine pseudoscientists, who spend their time trying to invent false claims about vaccine safety, HPV vaccine safety is nearly settled science, based on dozens of high quality clinical and epidemiological studies. Although the anti-vaccine religion would love you to believe that the vaccine kills their children, the scientific evidence decidedly refutes these assertions.
Anti-vaccine zealots illogically reject any circumstantial evidence that the HPV vaccine prevents cancer. That circumstantial evidence is based on powerful data that the vaccine prevents many strains of HPV infections, and we have similarly powerful data that many cancers are directly related to those same HPV infections – thus, if you stop the infection, it’s logical to accept that the vaccine will stop cancer. At least the logic makes sense to scientists, but apparently logic isn’t a top priority of pseudoscientific vaccine deniers.
Because HPV-related cancers can take years to show up – it’s a myth that cancers have some on-off switch that the causal factor instantly makes cancer appear – direct evidence has been difficult to research on whether HPV vaccines prevent cancer. But the HPV vaccine has been on the market for 10-15 years in most areas of the world, so if our hypothesis is correct, that the HPV vaccine prevents cancer, then maybe we can see a direct reduction in these cancers by now.
Guess what? We do have some of that direct evidence. Continue reading “HPV vaccine prevents cancer despite anti-vaccine fear, uncertainty, doubt”
I regularly write about Gardasil safety and effectiveness, because I consider the HPV vaccine one of top 100 greatest medical inventions over the past century or so. We have so few ways to prevent cancer, despite the nonsense pushed by pseudoscientists like the brainless Food Babe. And one of the best ways to prevent cancer is getting the HPV vaccine to prevent HPV related cancers.
I originally wrote this article around 5 years ago, but it needed updating on several issues since things have changed on this website. But why do I care about maintaining a 5-year-old article about Gardasil safety? Because this is one of the seminal articles about Gardasil safety, one that is important to anyone’s understanding of the subject.
Let’s get into it. Continue reading “Gardasil safety supported by a large study of 200 thousand young women”
Oral sex between couples in a relationship should be considered pleasurable and fun. Unfortunately, it may be dangerous, especially for men who have had a high number of oral sex partners. There is a new study that showed that this behavior is linked to HPV-related oropharyngeal cancers.
Lucky for those men and women who enjoy oral sex, there is a cancer preventing vaccine that reduces your risk of contracting HPV, thereby reducing your risk of getting the cancer. Let’s hope that this significant risk of a deadly and disfiguring cancer will convince people to get the vaccine for their children.
This article will look at HPV, the HPV cancer preventing vaccine, the new study on oral sex, and how you can protect your life. Continue reading “Oral sex and HPV-related cancer – another reason for HPV vaccine”
Here we go again – another lightweight “science paper” attacking Gardasil vaccine safety. Now, I have to spend time debunking it because we all know that this new article will be used as “proof” that Gardasil is dangerous.
As I have written dozens of times, there are precious few ways for us to effectively prevent cancer. Exercise regularly. Eat a balanced diet. Stay out of the sun. Quit smoking. Don’t drink alcohol. And get vaccinated against hepatitis B and the human papillomavirus (HPV). That’s it. No kale blueberry almond milk shake is going to suddenly make your risk of cancer drop to zero. Avoiding gluten, cleansing your colon, or smoking a joint will have no effect on your risk of cancer.
But the HPV cancer preventing vaccine, known as Gardasil, is a well-researched, scientifically-based medication to prevent a long list of cancers. So we’re going to take a critical look at this new article. Continue reading “Gardasil vaccine safety – under attack again by a false authority”
The greatest thing about science is that it relies upon evidence, while building the body of evidence over time. We know that evolution is a fact, not because of one piece of data, but because of thousands of individual data points over nearly 150 years. The body of evidence supporting HPV vaccine effectiveness, though not at the level of evolution research, is, nevertheless, robust and broad.
A new study suggests that the HPV vaccine effectiveness is much higher than originally believed, as shown by the reduction in the incidence of cervical neoplasia (including pre-cancers) since the introduction of the HPV vaccine.This is pretty exciting news.
Let’s take a look at the recently published paper that supports improved HPV vaccine effectiveness.

The cancer preventing HPV vaccine, known as Gardasil, Silgard, or Cervarix, is one of the very few ways available to actually reduce the risk of certain cancers. The vaccine reliably blocks HPV infections, which are directly linked to several dangerous cancers such as cervical cancer.
Unfortunately, most boys in the United States aren’t receiving the cancer-preventing HPV vaccine according to a new survey of teen vaccination from the CDC. This low HPV vaccine uptake may result from the failure of physicians to recommend the vaccine or adequately explain its benefits to parents.

I have written in the past about Dr. Diane Harper, a former Merck & Co. researcher who apparently had some management role in the clinical trials of the HPV quadrivalent vaccine, also known as Gardasil (or Silgard in Europe), which blocks the transmission of several types of human papillomavirus (HPV).
There are very few actions one can take in life to prevent even one of the 250 different types of cancer. Stop smoking. Keep a healthy weight. Stay out of the sun. And get an actual cancer preventing vaccine, like Gardasil.
The HPV cancer prevention vaccine is a vitally important part of the war against infectious diseases and some types of cancer. This vaccine blocks infection by several types of HPV. which are linked to approximately 70% of cervical cancers, and cause most HPV-induced anal (95% linked to HPV), vulvar (50% linked), vaginal (65% linked), oropharyngeal (60% linked) and penile (35% linked) cancers. These HPV-related cancers can be prevented as long as you can prevent the HPV infection itself, which are generally passed through genital contact, most often during vaginal, oral and anal sex.
According to the dark recesses of the internet that are devoted to the cause of denying the value of vaccines, Dr. Harper had decided to “come clean” about Gardasil so that she could “sleep at night.”
The antivaccination world has attached themselves to this story, because they think it uncovers a conspiracy or lies by the vaccine manufacturers, since obviously Dr. Harper escaped from the evil clutches of Big Pharma. And because antivaccinationists do their “research” by Google, of course, this story keeps getting repeated until it becomes The Truth™.

Genital human papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the USA. There are more than 40 HPV sub-types that can infect the genital areas of males and females. Additionally, some HPV types can also infect the mouth and throat. HPV is generally transmitted from personal contact during vaginal, anal or oral sex.
The new, more powerful, version of the HPV vaccine , recently cleared by the US Food and Drug Administration, protects teens and young adults from 9 subtypes of HPV, helping prevent more cancers. The new vaccine, called Gardasil-9, prevents even more types of cancer.
This newest version of the HPV cancer-preventing vaccine safely and effectively prevents several forms of cancer in young adults by protecting the those who receive the vaccine from nine different types of the HPV virus. In a clinical study, published in Pediatrics, 3066 girls and boys, aged 9 through 15, were given a three-dose series of the new Gardasil-9 vaccine–day 1, month 1, and month 6.
The researchers observed no serious adverse events and high immunogenicity (antibodies to all 9 HPV types).

During my long years in scientific research and medical device product development, one of the great goals that is often repeated (rarely by the researchers themselves but politicians and the public) is a prevention or “cure” for cancer. Setting aside the simple fact that there are over 250 different cancers, each with its own cause(s), pathophysiology, prognosis and cure(s), and setting aside the fact that we can cure some cancers, albeit with radical treatments, simple prevention and cures have been elusive.
Many people have hyped foods or supplements as “natural” prevention for cancers, but the evidence that any of these things work is missing. Or a myth. Or just don’t work.
Actually, one of the best ways to prevent cancer is get immunized against certain cancer causing viruses. And there is one medical discovery that can prevent one of these viruses. It’s easy to get the prevention. It’s very safe. And it really works. Continue reading “Man the barricades against the anti HPV vaccine barbarians”
