Key facts

HPV vaccination at a glance.

The essentials, in plain English - what the vaccine covers, who can have it and how it fits into the UK immunisation programme.

  • What it prevents

    Infection with the human papillomavirus types most linked to cervical, anal, vulval, vaginal, penile and oropharyngeal cancer, and to genital warts.

  • UK vaccine

    Gardasil 9 - a nine-valent vaccine covering HPV 6, 11, 16, 18, 31, 33, 45, 52 and 58.

  • School programme

    Offered in Year 8 to girls (since 2008) and boys (since 2019) - a single dose since September 2023.

  • NHS catch-up

    Free on the NHS for those who missed the school offer up to age 25.

  • Broader eligibility

    Men who have sex with men are eligible up to age 45, and immunocompromised patients are offered a three-dose schedule.

  • Private option

    Available privately from around £150 to £300 per dose - individually assessed up to age 45 and beyond.

Why this guide matters

One vaccine, several cancers prevented.

HPV vaccination is one of the highest-impact interventions in modern public health. The three points below shape everything else on this page.

  • It prevents multiple cancers

    Cervical, anal, oropharyngeal, vulval, vaginal and penile - Gardasil 9 targets the HPV types behind most of them.

  • One dose is now enough for most

    From 2023, immunocompetent adolescents and young adults receive a single dose - endorsed by WHO SAGE and JCVI.

  • Adults are still eligible

    NHS catch-up to 25, MSM to 45, immunocompromised on three doses, and private options up to 45 and beyond.

How the assessment is made

From enquiry to a first dose.

The steps a UK vaccination service will normally follow, in order - so you know what to expect and why.

  1. 01

    Assessing

    Eligibility review

    A structured check of age, sex, immune status and prior HPV vaccination history against JCVI and UKHSA eligibility.

  2. 02

    Assessing

    Risk and benefit conversation

    Discussion of expected protection against cervical, anal, oropharyngeal and other HPV-related cancers and genital warts.

  3. 03

    Assessing

    Medical history and allergies

    Screening for previous vaccine reactions, latex or yeast allergy, current illness and pregnancy status.

  4. 04

    Confirming

    Immune-status assessment

    HIV, transplant, chemotherapy or biologic therapy - all shift the schedule to a three-dose course.

  5. 05

    Confirming

    Post-conisation review

    For women treated for CIN, vaccination can reduce recurrence - a specialist gynaecology conversation is worth having.

  6. 06

    Delivering

    Dose scheduling

    Single dose for immunocompetent adolescents; three doses (0, 2 and 6 months) for immunocompromised or older adults where indicated.

  7. 07

    Delivering

    Aftercare and follow-up

    Fifteen minutes seated post-vaccine to reduce syncope, a record card and continued cervical screening as usual.

Typical timeline: from enquiry to first dose in a single appointment.

What it prevents

The HPV types and diseases that matter.

Human papillomavirus has more than 200 types. A small number of high-risk types drive most HPV-related cancers. Read more in our guide to HPV infection.

  • High-risk types

    HPV 16 and 18 cause around 70% of cervical cancer worldwide - 31, 33, 45, 52 and 58 add most of the rest.

  • Low-risk types

    HPV 6 and 11 cause more than 90% of genital warts - not cancer, but a major quality-of-life issue.

  • Cervical disease

    Persistent high-risk infection drives CIN and cervical cancer - see our guide on gynaecological cancers.

  • Oropharyngeal cancer

    HPV 16 is now the leading cause of tonsil and base-of-tongue cancer in UK men - see our head and neck cancer guide.

  • Anal, vulval, vaginal and penile cancer

    All strongly HPV-driven - vaccination cuts the risk of the pre-cancerous lesions that precede them.

  • Genital warts

    Common, distressing and often recurrent - Gardasil 9 has largely eliminated new cases in vaccinated cohorts.

  • Herd protection

    High uptake reduces circulation of high-risk HPV in the population - protecting the unvaccinated too.

  • Red flag - persistent HPV in adults

    Vaccination does not treat existing infection - persistent smear abnormalities need colposcopy, not another dose.

Eligibility and schedules

How HPV vaccination is delivered in the UK.

Set by JCVI, delivered by UKHSA and NHS England - with private and specialist routes to fill the gaps. Speak to our HPV vaccination clinic to arrange.

  • Gardasil 9 (nine-valent)

    The current UK vaccine - covers HPV 6, 11, 16, 18, 31, 33, 45, 52 and 58. Given intramuscularly into the deltoid.

  • Single-dose schedule

    Since 2023, immunocompetent adolescents and young adults receive one dose - endorsed by WHO SAGE and JCVI.

  • Three-dose schedule

    Immunocompromised patients (HIV, transplant, biologics) receive doses at 0, 2 and 6 months for reliable seroconversion.

  • School programme

    Offered in Year 8 (age 12 to 13) to girls and boys - the best age for a strong immune response before likely HPV exposure.

  • NHS catch-up up to 25

    Anyone eligible for the school programme who missed it can still be vaccinated free on the NHS up to their 25th birthday.

  • MSM programme up to 45

    Men who have sex with men are eligible via sexual health services up to age 45 - a two or three-dose course.

  • Private vaccination up to 45+

    Available privately with individual assessment - around £150 to £300 per dose, typically a three-dose course in older adults.

  • Post-conisation vaccination

    For women treated for CIN 2 or 3, vaccination may reduce recurrence - a growing evidence base and a specialist conversation.

What this guide is based on

The sources behind every claim on this page.

UK national guidance, WHO recommendations and Cochrane evidence, current at the time of last review.

Key references

Guidelines and standards we relied on.

A quiet reminder

This guide is for information, not medical advice.

Your GP, school nurse, sexual health clinic or private vaccination service can confirm which parts apply to you. If in doubt, ask.

  • Joint Committee on Vaccination and Immunisation (JCVI). Advice on the HPV immunisation programme.

  • UKHSA. Immunisation against infectious disease (the Green Book) - chapter 18a on HPV.

  • WHO Strategic Advisory Group of Experts (SAGE). HPV single-dose recommendation, 2022.

  • NHS England. HPV vaccination programme service specifications and eligibility.

  • Cochrane. Prophylactic vaccination against HPV to prevent cervical cancer and its precursors.

Cautions and red flags

When to pause and check first.

Most people can be vaccinated safely and without delay. These are the situations where a clinician will pause, review or adjust.

  • Severe allergy to a previous dose

    Anaphylaxis to a prior HPV dose or to any vaccine component (including yeast) is a contraindication - specialist immunology input needed.

  • Moderate or severe acute illness

    Defer vaccination until the acute illness has settled - minor colds are fine, febrile illness is not.

  • Pregnancy

    Not recommended in pregnancy as a precaution - inadvertent doses have not shown harm, but delay planned doses until after delivery.

  • Bleeding disorders

    Haemophilia or anticoagulation needs a fine needle, firm pressure and an experienced clinician - not a reason to skip the vaccine.

  • Syncope after injections

    Fainting is common in adolescents - vaccinate seated or lying down and observe for 15 minutes afterwards.

  • Persistent abnormal smear

    Vaccination is preventive, not curative - existing high-grade disease needs colposcopy, not vaccination alone.

  • Immunocompromise not previously flagged

    HIV, transplant or biologic therapy shifts the schedule to three doses - flag it before the first injection.

  • Concerns about MS, POTS or CFS

    Large studies have found no causal link between HPV vaccination and these conditions - safety data is reassuring.

After the jab

A safe vaccine, with lifelong benefits.

Four things that make the biggest difference - timing, ongoing screening, reassurance about safety and knowing that adult catch-up is still available.

A quiet reminder

Vaccination and screening work together.

The vaccine prevents most HPV-related cancers. Cervical screening catches the rest early.

  1. 01 Prevention

    Best given before exposure

    Vaccination works best before any HPV exposure - the school programme in Year 8 is the ideal age, but older ages still benefit.

  2. 02 Screening

    Keep going to cervical screening

    Vaccination reduces but does not eliminate cervical cancer risk - continue routine smear tests as invited.

  3. 03 Reassurance

    A well-studied vaccine

    Over 400 million doses given worldwide - the safety profile is one of the most studied of any vaccine in modern use.

  4. 04 Ask

    Missed the school offer? Ask

    NHS catch-up runs to age 25 - and MSM and immunocompromised eligibility extends further. Speak to a GP or sexual health clinic.

Frequently asked

Everything we get asked about HPV vaccination.

Quick answers on eligibility, Gardasil 9, the single-dose schedule, safety and adult catch-up.

  • Who is eligible for the HPV vaccine on the NHS?

    All Year 8 children (age 12 to 13) as part of the school programme, catch-up up to age 25 for those who missed it, men who have sex with men up to age 45 via sexual health services, and immunocompromised patients on a three-dose schedule. Eligibility is set by JCVI and delivered by UKHSA and NHS England.

  • Why does the UK now use a single dose?

    From September 2023, immunocompetent adolescents and young adults receive one dose of Gardasil 9. This follows WHO SAGE guidance and JCVI review of the evidence - a single dose produces high, sustained antibody responses and comparable protection against cervical pre-cancer to two or three doses in this group.

  • Which vaccine is used in the UK?

    Gardasil 9, a nine-valent vaccine from Merck. It covers HPV types 6 and 11 (which cause genital warts) and the seven high-risk oncogenic types 16, 18, 31, 33, 45, 52 and 58 - broader coverage than the earlier bivalent and quadrivalent vaccines.

  • Can I still get the vaccine as an adult?

    Yes. NHS catch-up runs to age 25 for those eligible for the school programme, and MSM up to 45 are eligible via sexual health services. Privately, individual assessment can support vaccination up to age 45 and beyond, typically as a three-dose course at around £150 to £300 per dose.

  • Is the HPV vaccine safe?

    Yes - the safety data is extensive and reassuring. The commonest side effects are local (sore arm, mild swelling) and short-lived. Fainting after injection is common in adolescents. Large, high-quality studies have found no causal link between HPV vaccination and multiple sclerosis, POTS or chronic fatigue syndrome.

  • Does the vaccine help after HPV infection or CIN treatment?

    It does not clear an existing infection. However, for women treated for CIN 2 or 3, growing evidence suggests HPV vaccination after conisation reduces the risk of recurrence. It is worth discussing with your gynaecologist alongside routine post-treatment follow-up.
