HPV Vaccination for Adults: Is It Too Late to Get Vaccinated?

What is HPV Vaccination for Adults

If you missed the HPV vaccine at school, or simply didn’t have the chance when you were younger, you might assume the window has closed. It hasn’t. Adults can still benefit meaningfully from Gardasil 9 vaccination, and at The Wright Practice we explain how the case for it changes with age, prior exposure and personal risk, so you can make an informed decision.

Adult HPV Vaccination at a Glance

A few quick answers before we go into more detail.

  • What is it: Gardasil 9, the vaccine used across the NHS and private clinics in the UK, protecting against nine HPV strains linked to cancer and genital warts.
  • Who it’s for: any adult who missed school-age vaccination, particularly those under 45 who haven’t yet been exposed to all nine strains.
  • Is it too late: usually not. Even sexually active adults are unlikely to have encountered every strain the vaccine covers.
  • Course length: most adults need two or three doses over several months, depending on age at the first dose.
  • Common side effects: mild soreness at the injection site, and occasionally a short-lived headache or low-grade fever.
  • Cost: available privately at The Wright Practice, priced per dose and confirmed at your consultation.

Can Adults Still Benefit From the HPV Vaccine?

Yes. Gardasil 9 protects against nine HPV strains, and it is very unlikely that any one person has already been exposed to every strain it covers, even after years of sexual activity. This means most adults still gain real protection from vaccination, whatever their age or history.

HPV itself is extremely common. Most sexually active people encounter at least one strain of the virus at some point, and the body usually clears it without any lasting effect. The vaccine’s value lies in protecting against the strains you haven’t yet met, particularly HPV-16 and HPV-18, which together are linked to around 70% of cervical cancers and the majority of HPV-related anal and throat cancers.

What Does Gardasil 9 Actually Protect Against?

Gardasil 9 is often thought of purely as a cervical cancer vaccine, but its protection is broader than that. It targets nine HPV types responsible for a wide range of conditions.

  • Cervical, vaginal and vulval cancers and precancerous changes
  • Anal cancer, in both men and women
  • A proportion of throat and other head and neck cancers
  • Genital warts, caused by two of the nine strains covered

This wider protection is one of the most common surprises for adult patients, who often assume the vaccine has no relevance for them if they are male, or past the age typically associated with cervical screening.

For more on how HPV relates to cervical health specifically, see our cervical health and screening page.

Understanding HPV

How Does This Differ From Cervical Screening?

It’s a common mix-up, but vaccination and screening do two different jobs. The HPV vaccine prevents infection with the strains it covers, reducing the chance of ever developing HPV-related changes in the first place.

Cervical screening, by contrast, detects HPV or cell changes that are already present. Vaccination does not remove the need for screening, and anyone eligible for cervical screening should continue attending as invited, regardless of vaccination status, since Gardasil 9 does not protect against every cancer-causing HPV strain.

Our cervical health and screening service covers what screening involves and how often it’s recommended.

What Does the Course Involve?

The number of doses you need depends on your age at your first appointment. Adults having their first dose at 15 or older, which covers the vast majority of adult patients, are usually advised to complete a course of two or three doses.

  • Two-dose schedule: suitable for many immunocompetent adults, typically given around six months apart, in line with current UK and World Health Organisation guidance.
  • Three-dose schedule: often recommended for adults starting later, or for anyone who is immunosuppressed or living with HIV, given at month 0, 1 to 2, and 6.
  • Timing flexibility: if a dose is delayed, there is no need to restart the course. Your clinician can pick up from where you left off.

Your clinician will confirm the most appropriate schedule for you at your first appointment, balancing strength of protection against the number of visits required.

If your main concern is your personal exposure risk rather than the vaccine itself, our guide to understanding your risk of HPV may help you decide how urgently to book.

Who Is a Good Candidate for Adult Vaccination?

May be suitable for

  • Anyone who missed the school-age HPV programme, now outside NHS catch-up eligibility
  • Adults up to around 45 who haven’t previously been vaccinated
  • Men who have sex with men, who face a higher risk of HPV-related anal and throat cancers
  • Anyone starting a new relationship who wants broader protection going forward
  • People who have already had one HPV strain diagnosed, since the vaccine still protects against the other eight

May not be suitable, or worth discussing further first

  • Anyone with a known severe allergy to a vaccine component
  • People who are currently unwell with a significant acute illness, who may need to wait until they’ve recovered
  • Those who are pregnant, where vaccination is usually deferred until after delivery

There’s no need to be tested for HPV or cervical changes before vaccination. Your clinician at The Wright Practice will talk through your individual history to confirm the right approach.

Side Effects and Safety

Gardasil 9 has an established safety record built on more than a decade of use across millions of doses worldwide.

  • Common: soreness, redness or mild swelling at the injection site, usually settling within a day or two.
  • Less common: a short-lived headache, mild fever, or feeling tired for a day after vaccination.
  • Rare: fainting shortly after the injection, more often seen in teenagers and young adults, which is why patients are usually asked to sit for a short period after the vaccine is given.

No serious safety concerns have been identified with Gardasil 9 in adults, and your clinician will talk through your individual medical history before your first dose to check the vaccine is right for you.

How Much Does Adult HPV Vaccination Cost at The Wright Practice?

The cost of HPV vaccination at The Wright Practice depends on the number of doses your schedule requires. This typically includes your initial consultation, the vaccine itself, and administration at each visit. Book a consultation for a tailored quote based on your age, history and recommended schedule.

Our Approach at The Wright Practice

“A lot of adults assume they’ve missed their chance with the HPV vaccine, and that simply isn’t true for most people,” says Dr Dan Wright. “The vaccine covers nine strains, and even with a full sexual history, it’s very unlikely anyone has been exposed to all of them. We take the time to talk through personal risk and prior exposure so each patient can make an informed decision, rather than assuming the vaccine no longer applies to them.”

This individually tailored approach runs across every consultation at our Harley Street clinic, including our wider vaccination and prevention services for sexual health.

Frequently Asked Questions about HPV Vaccination for Adults

Is it too late to get the HPV vaccine as an adult?

For most adults, no. Gardasil 9 covers nine HPV strains, and it’s very unlikely you’ve already been exposed to all of them, even after years of sexual activity. Vaccination can still offer meaningful protection well into adulthood.

Do I need to be tested for HPV before having the Gardasil vaccine?

No testing is required before vaccination. There’s no reliable way to check which specific strains you may already have encountered, so The Wright Practice recommends proceeding with vaccination based on your history and risk rather than pre-testing.

Can men benefit from the Gardasil vaccine too?

Yes. HPV causes genital warts, anal cancer and some throat cancers in men, not only cervical cancer in women. Men who have sex with men face a particularly elevated risk of HPV-related anal and throat cancers, making vaccination especially relevant.

How many doses of Gardasil 9 will I need as an adult?

This depends on your age and health at your first dose. Most adults need either two doses around six months apart, or three doses over six months if starting later or if immunosuppressed. Your clinician will confirm the right schedule for you.

Does the HPV vaccine replace the need for cervical screening?

No. Gardasil 9 doesn’t protect against every HPV strain linked to cervical cancer, so screening remains important even after vaccination. The vaccine prevents infection; screening detects changes that may already be present.

I've already had an abnormal smear or genital warts. Is vaccination still worth it?

Often, yes. A previous HPV-related diagnosis usually involves only one strain, and Gardasil 9 still protects against the other eight. Your clinician at The Wright Practice can talk through whether vaccination makes sense given your specific history.

Is the Gardasil vaccine safe for adults over 40?

Yes. Gardasil 9 is licensed for use up to age 45 and has a well-established safety profile in this age group. Your clinician will review your medical history at your consultation to confirm there’s no reason vaccination wouldn’t be appropriate for you.

What happens if I delay a dose or miss an appointment?

There’s no need to restart your Gardasil 9 course if a dose is delayed. Your clinician at The Wright Practice can simply continue from where you left off, whatever the gap since your last dose.

Can I get the HPV vaccine on the NHS as an adult?

NHS HPV vaccination is generally limited to those under 25, along with some specific eligible groups through sexual health clinics. Most adults outside these criteria access Gardasil 9 privately, which is available at The Wright Practice.

Will the HPV vaccine protect me if I'm already sexually active?

Yes, in most cases. Being sexually active doesn’t mean you’ve encountered every HPV strain the vaccine covers, so vaccination still offers real, additional protection against the strains you haven’t yet met.

Missing the school programme doesn’t mean the HPV vaccine no longer has anything to offer you. Book a consultation with The Wright Practice today to check your suitability and get started.
