Human papillomavirus is one of the most common viral infections in the world, yet it remains widely misunderstood. The HPV vaccine is one of the most significant advances in preventative healthcare of the past two decades, offering protection against the strains of the virus responsible for the majority of cervical cancers, several other HPV-related cancers, and genital warts. In the UK, it is part of the routine childhood immunisation schedule and is also available to adults who missed their school-age vaccination. Whether you are a parent researching your child’s upcoming vaccination, an adult who was not vaccinated in school, or someone who simply wants to understand more about how HPV protection works, this guide covers everything you need to know.
At Vivo Pharmacy & Health Clinic in Bristol, we provide HPV vaccinations as part of our private immunisation service, alongside a range of other travel and preventative health vaccinations. Book a vaccination appointment in Bristol or contact our team to find out more.

What Is HPV and Why Does It Matter?
Human papillomavirus is not a single virus but a family of over 200 related viruses, transmitted primarily through skin-to-skin sexual contact. Most sexually active people will contract at least one strain of HPV at some point in their lives. In the majority of cases, the immune system clears the infection naturally within one to two years without causing any symptoms or long-term harm.
However, certain high-risk strains of HPV, particularly types 16 and 18, can cause persistent infection that over time leads to cell changes in the cervix, anus, throat, penis, vulva, and vagina. These changes can develop into cancer if left undetected and untreated. HPV types 16 and 18 are responsible for approximately 70% of cervical cancers in the UK, making them the primary target of current vaccination programmes.
Lower-risk strains, particularly types 6 and 11, do not cause cancer but are responsible for the vast majority of genital wart cases.
According to NHS guidance on HPV, around 8 in 10 people will be infected with HPV at some point in their lives. The absence of symptoms in most cases means many people carry and transmit the virus without knowing it, which is precisely why vaccination before potential exposure is so important.
What Diseases Does the HPV Vaccine Protect Against?
The HPV vaccine used in the UK is Gardasil 9, which protects against nine strains of HPV. Understanding exactly what it protects against helps explain why it is described as one of the most impactful vaccines ever developed.
The UK HPV Vaccination Programme: Who Is Eligible on the NHS?
The UK has one of the most comprehensive national HPV vaccination programmes in the world. Gardasil 9 is the vaccine currently used across all four UK nations. Understanding who qualifies for NHS-funded vaccination and under what conditions is important for planning your own or your child’s protection.
Routine School-Age Programme
The HPV vaccine is routinely offered in school Year 8 in England (and equivalent year groups in Scotland, Wales, and Northern Ireland) to all young people aged 12 to 13, regardless of gender. The programme was initially offered only to girls when it launched in 2008 but was extended to boys in September 2019, recognising that HPV-related cancers affect all genders and that vaccinating boys also reduces transmission to women.
From September 2023, a single dose of Gardasil 9 was introduced for those aged 11 to 14 who are starting their HPV vaccination course, based on evidence demonstrating equivalent immunological protection at younger ages when the immune response is strongest. Those who had already received one dose before September 2023 are also considered to have completed their course under the updated guidance.
NHS Catch-Up Programme for Under 25s
Anyone who missed their school-age vaccination can receive it free on the NHS up to and including their 25th birthday. The eligibility and dose schedule for this group depend on the age at which the course is started and the interval between doses.
MSM (Men Who Have Sex With Men) Programme
The NHS also offers free HPV vaccination to men who have sex with men up to and including the age of 45, through sexual health clinics and some GP surgeries. This group was identified as having a significantly higher risk of HPV-related anal cancer, and evidence supports vaccination even in those who may have already been exposed to some HPV strains.
HIV-Positive Individuals
People living with HIV are eligible for free HPV vaccination through sexual health or HIV clinics up to the age of 45, due to the significantly higher risk of HPV-related cancers associated with immune suppression.
How Many Doses of the HPV Vaccine Do You Need?
The number of doses required depends on your age and immune status at the time you start your HPV vaccination course. The following table summarises the current UK dosing schedule.
| Age at First Dose | Number of Doses | Recommended Schedule | NHS Funded? |
|---|---|---|---|
| Under 15 (from September 2023) | 1 dose | Single dose | Yes (school programme) |
| 15 to 24 (catch-up) | 2 doses | 0 and 6 to 12 months | Yes (up to 25th birthday) |
| 25 and over (standard immune status) | 3 doses | 0, 2, and 6 months | Private only (except eligible groups) |
| Any age with immunocompromised | 3 doses | 0, 2, and 6 months | Yes (via specialist services) |
| MSM up to age 45 | 3 doses | 0, 2, and 6 months | Yes (via sexual health clinics) |
Adults Who Missed the School-Age Vaccination: Is It Too Late?
This is one of the most frequently asked questions about the HPV vaccine, and the reassuring answer is no, it is not too late for most adults. While vaccination is most effective before any exposure to HPV, meaning before sexual activity begins, the vaccine still provides meaningful protection against strains not yet encountered, even in sexually active adults.
The logic behind this is straightforward. With over 200 HPV strains in circulation and most people unlikely to have been exposed to all nine strains covered by Gardasil 9, vaccination in adulthood still reduces future cancer risk even if some prior exposure has occurred. The vaccine cannot treat an existing HPV infection, but it can prevent future infection with the strains it covers.
For those between 25 and 45 who want private HPV vaccination, a three-dose course is recommended. The cost of private HPV vaccination varies between providers. Our team can advise on current pricing and availability at our Bristol clinic.
How Does the HPV Vaccine Work?
Gardasil 9 is a recombinant vaccine, meaning it does not contain live virus. Instead, it contains virus-like particles (VLPs) made from the outer protein shell of nine HPV types. These particles are structurally identical to the outer surface of the actual virus but contain no genetic material, meaning they cannot cause infection.
When injected, the immune system recognises these particles as foreign and mounts an antibody response. Because the particles are structurally identical to the real virus, this produces robust, lasting immunity. If the vaccinated person subsequently encounters the actual virus, their immune system is primed to neutralise it before it can establish infection.
The antibody levels generated by HPV vaccination are significantly higher than those produced by natural infection, which explains why vaccinated individuals have stronger and more durable protection than those who have had and cleared a natural HPV infection.
How Effective Is the HPV Vaccine?
The clinical evidence supporting HPV vaccination is among the strongest in vaccine science. Real-world data from the UK’s national programme has demonstrated dramatic reductions in HPV-related disease since the vaccine was introduced.
These figures represent some of the most compelling real-world evidence of any vaccine in modern medicine. A landmark study published in The Lancet in 2021 by Falcaro et al. found that girls vaccinated at age 12 to 13 had an 87% reduction in cervical cancer rates, with near-complete elimination of HPV types 16 and 18 in many regions of the UK. The data strongly support the conclusion that widespread HPV vaccination has the potential to effectively eliminate cervical cancer as a public health problem in the coming decades.
How Long Does the HPV Vaccine Last?
Long-term follow-up data from clinical trials and national programmes consistently show that protection from the HPV vaccine is durable. Studies tracking vaccinated individuals for over 15 years have found no significant decline in antibody levels, and booster doses are not currently recommended by UK health authorities.
The single-dose schedule introduced in 2023 for under-15s is supported by clinical evidence demonstrating non-inferior immunogenicity compared to the two-dose schedule in younger age groups. While the long-term durability of single-dose protection is still being studied, current evidence strongly supports its effectiveness.
It is worth contextualising this alongside other vaccines in our portfolio. Hepatitis A vaccination, for example, offers protection for approximately 25 years after completing the course, while yellow fever vaccination is generally considered to provide lifelong protection after a single dose. Our guide on how long the hepatitis A vaccine lasts provides more detail on the duration of protection for this common travel vaccine. Similarly, our resource on how long the yellow fever vaccine lasts covers the duration of immunity for travellers. The HPV vaccine’s durability appears comparable to or better than that of many established vaccines.
Is the HPV Vaccine Safe?
The HPV vaccine has one of the most extensive safety records of any vaccine in the modern immunisation programme. It has been administered to hundreds of millions of people worldwide since 2006, and its safety profile is consistently confirmed by surveillance data from national health authorities, including the UK’s Medicines and Healthcare products Regulatory Agency (MHRA).
Common Side Effects
Side effects from the HPV vaccine are almost always mild and short-lived. The most commonly reported include:
- -> Injection site reactions: Redness, swelling, or mild pain at the injection site are the most frequently reported side effects. These typically resolve within one to three days.
- -> Headache: Mild headache is reported by some recipients, particularly in the first 24 hours after vaccination.
- -> Dizziness or fainting: Brief dizziness is occasionally reported immediately after injection, which is why recipients are asked to remain seated for 15 minutes post-vaccination.
- -> Mild fever: A low-grade temperature in the hours following vaccination is a normal immune response and not a cause for concern.
- -> Nausea: Mild nausea is occasionally reported but is typically brief and does not require treatment.
Serious Side Effects
Serious adverse reactions to the HPV vaccine are extremely rare. Anaphylaxis, a severe allergic reaction, can occur with any vaccine and is why vaccination always takes place in a clinical setting where staff are trained to respond. The rate of anaphylaxis following HPV vaccination is approximately 1.7 per million doses administered, which is comparable to other vaccines.
There is no credible clinical evidence linking the HPV vaccine to serious long-term conditions, including chronic fatigue syndrome, complex regional pain syndrome, or autoimmune conditions. Multiple large-scale safety studies across different populations have consistently failed to find any causal association between the vaccine and these conditions.
Who Should Not Receive the HPV Vaccine?
The HPV vaccine is contraindicated for people with a known severe allergy to any component of Gardasil 9, including yeast. It is not recommended during pregnancy. People who are moderately or severely unwell at the time of their appointment should postpone vaccination until they have recovered. Always inform your clinician of any allergies or current health conditions before vaccination.
Does the HPV Vaccine Mean You No Longer Need Cervical Screening?
No. Cervical screening (previously known as the smear test) remains essential even for people who have been vaccinated against HPV. The reasons for this are important to understand.
Gardasil 9 protects against the nine HPV strains responsible for approximately 90% of cervical cancers, but it does not provide complete protection against all cancer-causing strains. Cervical screening detects abnormal cell changes caused by HPV, including changes caused by strains not covered by the vaccine. The two programmes work together to provide the most comprehensive protection against cervical cancer.
Women and people with a cervix who have been vaccinated should continue to attend cervical screening when invited, according to the NHS screening schedule.
HPV Vaccination and Travel Health
HPV vaccination is increasingly relevant in the context of travel health, particularly for individuals planning extended stays abroad, gap years, or travel to regions with less comprehensive screening programmes.
In many parts of the world, cervical cancer remains one of the leading causes of cancer death in women, primarily because national vaccination and screening programmes are not as advanced as in the UK. Travellers who have not completed their HPV vaccination course before departing the UK may find access to Gardasil 9 abroad limited, expensive, or of uncertain authenticity.
If you are planning travel and have not yet completed your HPV vaccination, booking in advance of your departure is strongly advisable. This is particularly relevant for those travelling to regions such as India, Southeast Asia, sub-Saharan Africa, and Central America, where HPV-related disease burden remains high.
Our team provides comprehensive travel health consultations that cover all recommended vaccinations for your destination alongside general health preparation. Whether you need HPV vaccination, typhoid protection, or a full pre-travel assessment, we can provide everything in one appointment. Our detailed guide on travel injections for India provides a useful overview of the range of vaccinations that may be recommended for certain destinations. Similarly, our typhoid jab guide for Bristol covers one of the most commonly needed travel vaccines and how to access it alongside HPV vaccination in a single appointment.

Frequently Asked Questions About the HPV Vaccine
Can men get the HPV vaccine privately in the UK?
Yes. Men who do not qualify for the NHS-funded MSM programme or who are over the age of 45 can access HPV vaccination privately. All genders benefit from HPV vaccination as the virus causes cancers in both men and women. HPV-related oropharyngeal cancer in men is increasing in incidence and vaccination provides meaningful protection regardless of gender.
Is there any point getting vaccinated if I have already had HPV?
Yes. Most people who have had an HPV infection will only have been exposed to one or a small number of the nine strains covered by Gardasil 9. Vaccination still provides protection against the strains not previously encountered. The vaccine cannot treat an existing active infection or reverse changes already caused by HPV, but it meaningfully reduces future cancer risk even in those with prior exposure.
Does the HPV vaccine protect against all HPV-related cancers?
Gardasil 9 protects against the nine HPV strains responsible for approximately 90% of cervical cancers and a high proportion of other HPV-related cancers. It does not protect against all HPV strains, which is why cervical screening remains essential. The combination of vaccination and regular screening provides the most comprehensive protection currently available.
Can I have the HPV vaccine at the same time as other vaccines?
Yes. The HPV vaccine can generally be co-administered with other vaccines at separate injection sites. This is particularly useful in a travel health context, where multiple vaccinations may be needed before departure. Our clinicians will advise on the safest and most convenient schedule for your individual situation, including any vaccines recommended for your destination.
I had the older HPV vaccine (Cervarix or Gardasil 4). Do I need Gardasil 9?
If you received Cervarix or the original four-strain Gardasil, you have protection against HPV types 16 and 18, which are responsible for approximately 70% of cervical cancers. Gardasil 9 extends protection to five additional high-risk strains and to types 6 and 11 (which cause genital warts). Whether it is worth receiving Gardasil 9 as an additional course is a question for your clinician, who can assess the benefit based on your individual circumstances and the strains you may have previously been vaccinated against.
Is the HPV vaccine recommended before travel to certain destinations?
While HPV vaccination is not a compulsory travel requirement for any destination, it is recommended as part of a comprehensive preventative health approach for individuals who have not completed their course, particularly those travelling for extended periods. In many countries, access to HPV-related healthcare, screening, and vaccination is significantly less available than in the UK, making pre-travel vaccination all the more important.
