There is no other vaccine like it. While most vaccines protect against infectious diseases, the HPV vaccine does something no other immunization can: it prevents cancer. Not just one type of cancer, but several. And after nearly two decades of real-world evidence across millions of people, the results are nothing short of remarkable.
At Advance Medical of Naples, we believe every patient and every parent deserves to understand the full scope of what this vaccine offers. This article is designed to give you an expert-level understanding of HPV, the cancers it causes, and why vaccination is one of the most important health decisions you can make for yourself and your family.
Understanding HPV: The Most Common Sexually Transmitted Infection
Human papillomavirus (HPV) is a group of more than 200 related viruses. It is spread through intimate skin-to-skin contact, including vaginal, anal, and oral sex. HPV is so common that nearly every sexually active person will be exposed at some point in their life. The CDC estimates that approximately 42 million Americans are currently infected, with roughly 13 million new infections occurring each year.
In most people, the immune system clears HPV within one to two years without any symptoms or health consequences. But in a percentage of individuals, certain high-risk strains of the virus persist. These persistent infections can trigger changes in the DNA of healthy cells, causing them to grow abnormally. Over time, those cellular changes can develop into cancer. This process is slow, often taking 10 to 20 years or longer, which is why many HPV-related cancers appear in middle-aged and older adults whose exposure occurred decades earlier.
The Cancers Caused by HPV
HPV is directly responsible for a significant portion of cancers across multiple organ systems:
- Cervical cancer: Approximately 99.7% of cervical cancers are caused by persistent HPV infection. This makes cervical cancer a virtually vaccine-preventable disease.
- Oropharyngeal cancer (throat, base of tongue, tonsils): HPV is now the primary driver of these cancers, responsible for roughly 70% of cases. Oropharyngeal cancer has surpassed cervical cancer as the most common HPV-related cancer in the United States.
- Anal cancer: Over 90% of anal cancers are associated with high-risk HPV.
- Vaginal and vulvar cancers: Approximately 70% are linked to HPV.
- Penile cancer: About 60% of cases are associated with HPV.
In total, HPV is estimated to cause approximately 36,000 new cancer cases in the United States each year.
A Growing Crisis in Men: HPV-Related Throat Cancer
One of the most significant and underrecognized trends in cancer today is the dramatic rise of HPV-related oropharyngeal cancer in men. Each year, more than 18,700 men are diagnosed with oropharyngeal cancer compared to roughly 3,800 women. Men are affected at nearly five times the rate of women, and the incidence continues to climb.
The typical patient does not fit the profile most people associate with throat cancer. These are often nonsmoking, otherwise healthy men in their 50s, 60s, or 70s. Their cancer is not caused by tobacco or alcohol. It is caused by HPV exposure that occurred years or decades earlier, often through oral sexual contact. Because HPV infections rarely produce symptoms, these men had no way of knowing they carried the virus.
The most common first sign is a painless lump in the neck, which represents the cancer having spread to a lymph node. Other symptoms may include persistent sore throat, difficulty swallowing, ear pain, or a sensation that something is lodged in the throat.
Researchers project that if current trends continue, oropharyngeal cancer could become one of the most common cancers in middle-aged men in the United States within the next two decades. Unlike cervical cancer, there is currently no routine screening test for HPV in the throat. This makes vaccination and awareness the most effective tools we have.
Why Vaccinating Boys Is Just as Important as Vaccinating Girls
When the HPV vaccine was first introduced in 2006, public health messaging focused primarily on girls and cervical cancer prevention. Routine vaccination for boys was not recommended until 2011. As a result, there is an entire generation of men who were never vaccinated, and many parents still do not realize that boys need this vaccine too.
The data could not be more clear. HPV is actually more common in men than in women, and men currently bear the largest burden of HPV-related oropharyngeal cancer. Additionally, men have no routine HPV screening test equivalent to the cervical Pap smear or HPV test available to women. For men, vaccination is the primary line of defense.
By vaccinating both boys and girls, we also reduce the overall circulation of HPV in the community, creating a protective effect that benefits everyone, including those who are unvaccinated.
The Evidence: Nearly Two Decades of Proven Results
The HPV vaccine has now been in use for nearly 20 years, and the evidence base is extraordinary:
- Scotland (population-based study): After more than a decade of follow-up, no cases of cervical cancer were recorded among women who received the HPV vaccine at ages 12 to 13. Researchers described this as strong population-level evidence that the vaccine was protecting an entire generation.
- The Netherlands (national data, published 2025): Fully vaccinated women had approximately a 90% lower risk of developing invasive cervical cancer compared to unvaccinated women, representing one of the strongest real-world demonstrations of the vaccine’s impact to date.
- Costa Rica (randomized clinical trial, published December 2025 in the New England Journal of Medicine): A single dose of HPV vaccine provided approximately 97% protection against persistent infection with the most dangerous HPV strains, comparable to two doses. This landmark finding could reshape global vaccination strategies.
- Global impact: By the end of 2025, 159 countries had introduced HPV vaccination programs. The global vaccine alliance Gavi estimates that its HPV vaccine programs have prevented more than 1.4 million cervical cancer deaths.
The safety record is equally robust. Across clinical trials and post-marketing surveillance involving tens of millions of doses, no evidence has emerged linking HPV vaccination to any serious long-term adverse effects. The most commonly reported side effects are mild injection-site soreness, headache, and brief dizziness.
Who Should Get the HPV Vaccine?
The CDC recommends HPV vaccination for all children, both boys and girls, ideally beginning at ages 9 through 12. Vaccination at this age produces the strongest immune response and ensures protection well before any potential HPV exposure.
- Ages 9 through 12 (recommended): The ideal window. The vaccine can be given as early as age 9.
- Ages 13 through 26 (catch-up): If not vaccinated earlier, catch-up vaccination is strongly recommended for all teens and young adults.
- Ages 27 through 45 (shared decision-making): Adults in this age range who were not previously vaccinated may benefit. Talk with your provider about whether vaccination is appropriate based on your individual risk.
Gardasil 9, the vaccine currently used in the United States, protects against nine HPV types, including the seven most commonly associated with cancer (types 16, 18, 31, 33, 45, 52, and 58) and two types that cause genital warts (types 6 and 11).
Vaccination Does Not Replace Screening
While the HPV vaccine is extraordinarily effective, it does not eliminate the need for continued cancer screening. Women should still undergo cervical cancer screening (Pap test and/or HPV test) according to their provider’s recommendations. The vaccine does not protect against HPV types to which a person may have already been exposed, and it does not treat existing infections or pre-cancerous changes.
For men, no routine screening test currently exists for HPV-related throat cancer. This reality underscores the importance of vaccination as the primary prevention strategy, along with awareness of symptoms such as a painless neck lump, persistent sore throat, or difficulty swallowing.
Take Action: Protect Your Family
The HPV vaccine represents a once-in-a-generation opportunity in cancer prevention. It is safe, effective, and available today. If your child has not yet been vaccinated, if you are a young adult who missed it, or if you are an adult under 45 who wants to explore whether vaccination is right for you, we encourage you to take that step.
