The HPV vaccine: one shot that prevents six cancers
Applies to: Cervical, Anal, Oropharyngeal (throat), Penile, Vaginal, Vulvar
Most people think of the HPV vaccine as a "girls’ shot for cervical cancer." It’s far more than that: it prevents six different cancers in everyone, and for five of them, the vaccine is your main line of defense because there’s no screening test.
Full guide
The bottom line
HPV (human papillomavirus) is the most common sexually transmitted infection — about 85% of people get it at some point. Usually it clears on its own. But persistent infection with high-risk types causes six kinds of cancer: cervical, anal, oropharyngeal (throat), penile, vaginal, and vulvar. The HPV vaccine can prevent more than 90% of these — an estimated 33,700 cancers every year in the U.S. that simply wouldn’t happen if everyone were vaccinated.
Why this belongs in prevention, not just "women’s health"
Here’s the fact almost nobody knows: cervical cancer is the ONLY HPV-caused cancer with a recommended screening test. For anal, throat, penile, vaginal, and vulvar cancers, there’s no Pap-smear equivalent — they often aren’t caught until they cause symptoms. That means for five of the six, the vaccine is your primary protection, not a backup. And throat cancer from HPV is now the most common HPV-associated cancer, rising especially in men. This is not a "girls’ vaccine." It protects everyone. (For symptom recognition, see On Watch.)
Who should get it, and when
The vaccine works best given before any exposure to HPV, which is why it’s routinely recommended at ages 9–12 for all kids regardless of sex. But it’s also recommended as catch-up through age 26, and adults ages 27–45 who might still benefit can get it after a conversation with their doctor. If you weren’t vaccinated as a kid, and many adults over 30 never were offered it. It may not be too late.
- Kids 9–12: the ideal window (2 doses)
- Teens and adults through 26: catch-up vaccination, recommended
- Adults 27–45: talk to your doctor. You may still benefit depending on your history
- Everyone, regardless of sex or gender. This protects men and women
It works even if you’re already screened
If you’re a woman getting regular Pap/HPV tests, the vaccine still adds protection — screening catches cervical changes, but the vaccine prevents the infection that causes them in the first place, AND protects against the non-cervical HPV cancers that screening can’t catch. Belt and suspenders. (See the cervical guidance in The Screening Room for Pap/HPV testing.)
The one honest caveat
The vaccine doesn’t cover every cancer-causing HPV type, so vaccinated women should still do routine cervical screening. And it’s prevention, not treatment. It doesn’t clear an infection you already have. But as a piece of cancer prevention you can actually control, it’s one of the most effective tools that exists.
What to do
Ask your doctor: "Am I (or my kids) up to date on the HPV vaccine? Given my age and history, would I benefit?" Check with your insurance — it’s covered as preventive care for the recommended ages under the ACA. For kids, it’s part of the routine schedule. For adults who missed it, it’s worth the conversation.
