Married and Unvaccinated? Adults Still Need the HPV Vaccine

If you’re married, it’s easy to think: “I don’t need the HPV vaccine anymore.”

But here’s the truth: the HPV vaccine for adults can still matter, even if you’re in a committed relationship.

HPV (human papillomavirus) is very common. Most people get it at some point, often without symptoms. And some HPV types can lead to cancer later in life. The good news is that HPV vaccination helps prevent new HPV infections and prevention is powerful.

What HPV is ?

HPV is a virus that spreads through intimate skin-to-skin contact. Many people never know they have it. Most HPV infections go away on their own, but some high-risk types can cause cancers, especially cervical cancer.

That’s why the HPV vaccine is a big deal: it’s one of the best tools we have to stop HPV before it causes serious disease.

Why this matters in Nigeria

Cervical cancer is a major health problem in Nigeria. According to the International Agency for Research on Cancer (IARC/WHO), Nigeria had an estimated 13,676 new cervical cancer cases and 7,093 deaths in 2023. (IARC / WHO Global Cancer Observatory – Nigeria Fact Sheet)

Globally, the World Health Organization (WHO) reports around 660,000 new cases and 350,000 deaths from cervical cancer in 2022. (World Health Organization – Cervical Cancer Fact Sheet)

Nigeria has already taken an important step. WHO Africa reports Nigeria introduced HPV vaccination into routine immunization with a drive aiming to reach 7.7 million girls aged 9–14. (WHO Africa – Nigeria HPV Vaccine Introduction)

That program is focused on girls because the vaccine works best before exposure. But adults who missed it still have a chance to protect themselves.

“But I’m married…” 5 reasons HPV risk can still exist

Marriage does not magically block HPV. Here are five real-world reasons adults can still benefit from thinking about the HPV vaccine:

1) You or your partner may have been exposed years ago

HPV can be picked up earlier in life. People can carry HPV without knowing.

2) HPV can show up again later

Research in women ages 35–60 found a new high-risk HPV detection rate of 5.0 per 1000 woman-months. New partners increased risk a lot, but they explained only 19.4% of new detections—meaning many detections likely came from HPV acquired earlier and later “re-detected.”

In simple terms: HPV can sometimes “hide” and then show up again.

3) Life changes happen

Some people remarry, separate, or have a new partner later. Planning ahead is not about judging anyone—it’s about protecting your health.

4) Men matter too

HPV isn’t just a “women’s issue, men develop HPV-related disease too. Protecting men also helps protect women.

5) The vaccine can still protect against types you haven’t met yet

Even if someone has had HPV before, they may not have had all the vaccine-covered types. Vaccination can still add protection against types you haven’t been exposed to.

Does the HPV vaccine work for adults?

Yes—especially for preventing future infections.

A long-term follow-up of a major clinical trial found the quadrivalent HPV vaccine showed durable protection up to 10 years (median 8.9 years after dose 3), with sustained antibody responses in women aged 27–45. The study also found immune responses in men 27–45 were non-inferior compared with younger men, supporting benefit in mid-adult men as well.

Important to know:

•

HPV vaccines prevent new infections

•

They do not treat an HPV infection you already have

That’s still great news—because preventing the next infection is how we who are unvaccinated, especially in two groups.

If you are 26 or younger and unvaccinated

This is the simplest situation: get vaccinated now. Catching up earlier is better.

If you are 27–45 and unvaccinated

Many adults in this age range can still benefit, depending on their risk of future HPV exposure.

In U.S. guidance (often cited globally as clinical background), ACIP recommended shared clinical decision-making for some adults aged 27–45, recognizing that some may still be at risk for new HPV infection and might benefit. (CDC MMWR – HPV Vaccination for Adults).

In plain language: Talk with a clinician if you’re 27–45 and unvaccinated—especially if:

•

you might have a new partner now or in the future

•

you want added protection for peace of mind

•

you and your partner want to reduce HPV risk

Is the HPV vaccine safe?

Large reviews and guidance documents support the safety profile of HPV vaccination, including in adult studies.

Will the vaccine cure HPV if I already have it?

No. It helps prevent new infections, not treat current ones.
