It helps protect them against cervical cancer, which is the most common cancer in women under 35 in the UK.
In England, girls aged 12 to 13 years are routinely offered the first HPV vaccination when they’re in school year 8.
The second dose is normally offered 6 to 12 months after the first (in school year 8 or year 9).
The HPV vaccine is effective at stopping girls getting the types of HPV that cause most cervical cancers. It’s important to have both doses to be protected.

What is HPV?
HPV is the name given to a very common group of viruses.
There are many types of HPV, some of which are called “high risk” because they’re linked to the development of cancers, such as cervical cancer. Other types can cause conditions like warts or verrucas.
Nearly all cervical cancers (99.7%) are caused by infection with a high-risk type of HPV. HPV infections do not usually cause any symptoms, and most people will not know they’re infected.

What are the different types of HPV and what do they do?
There are more than 100 different types of HPV and around 40 that affect the genital area.
HPV is very common and can be caught through any kind of sexual contact with another person who already has it.
Most people will get an HPV infection at some point in their lives, and their bodies will get rid of it naturally without treatment.
But some women infected with a high-risk type of HPV will not be able to clear it.
Over time, this can cause abnormal tissue growth as well as other changes in the cells of their cervix, which can lead to cervical cancer if not treated.
High-risk types of HPV are also linked to other types of cancer, including:
Infection with other types of HPV may cause:
How does the HPV vaccine work?
Currently, the national NHS HPV vaccination programme uses a vaccine called Gardasil.
Gardasil protects against 4 types of HPV: 6, 11, 16 and 18. Between them, types 16 and 18 are the cause of most cervical cancers in the UK (more than 70%).
HPV types 6 and 11 cause nearly all cases of genital warts (90%), so using Gardasil helps protect girls against both cervical cancer and genital warts.
HPV vaccination does not protect against other infections spread during sex, such as chlamydia, and it will not stop girls getting pregnant, so it’s still very important to practise safe sex.
Who can have the HPV vaccine through the NHS vaccination programme?
The first dose of the HPV vaccine is routinely offered to girls aged 12 and 13 in school year 8.
The second dose is normally offered 6 to 12 months after the first (in school year 8 or year 9). The HPV vaccine helps protect against cervical cancer.
Girls who miss either of their HPV vaccine doses should speak to their school immunisation team or their GP surgery and make an appointment to get up to date as soon as possible.
It’s important to have both doses of the vaccine to be fully protected.
Girls can have the HPV vaccination on the NHS up to their 18th birthday.
Girls who start the HPV vaccination after the age of 15 will need 3 doses as they don’t respond as well to 2 doses as younger girls do.

Why is the HPV vaccine given at such a young age?
HPV infections can be spread by any skin to skin contact, and are usually found on the fingers, hands, mouth and genitals.
This means the virus can be spread during any kind of sexual activity, including touching.
The HPV vaccine works best if girls get it before they come into contact with HPV – in other words, before they become sexually active.
So getting the vaccine when recommended will help protect them during their teenage years and beyond.
Most unvaccinated people will be infected with some type of HPV at some time in their life. In most cases, the virus does not do any harm because their immune system clears the infection.
But in some cases, the infection stays in the body for many years and then, for no apparent reason, it may start to cause damage.
Cervical screening (sometimes called a smear test) can detect these changes. The person can then be treated to stop cancer developing.

HPV vaccination for men and boys
Cervical cancer does not affect boys and men because they do not have a cervix. But other cancers that can affect men – such as cancer of the anus, penis, mouth and throat – are also linked to infection with HPV 16 and 18.
In addition, HPV types 6 and 11 are responsible for the majority of genital wart infections.
Vaccinating girls indirectly helps protect boys from these types of cancer and genital warts because vaccinated girls will not pass HPV on to them. This is known as “herd immunity”.
The number of genital wart infections in the UK has already fallen in both girls and boys because of the vaccination programme.
Men who have sex with men (MSM) do not benefit in the same way from the girls’ programme so may be left unprotected from HPV.
From April 2018, MSM up to and including the age of 45 are eligible for free HPV vaccination on the NHS when they visit GUM (genitourinary medicine) clinics and HIV clinics in England.
Ask the doctor or nurse at the clinic for more details.
HPV vaccination for transgender people
Trans women (people who were assigned male at birth) are eligible in the same way as MSM if their risk of getting HPV is similar to the risk of MSM who are eligible for the HPV vaccine.
Trans men (people who were assigned female at birth) are eligible if they have sex with other men and are aged 45 or under.
If trans men have previously completed a course of HPV vaccination as part of the girls’ HPV vaccine programme, no further doses are needed.
How is the HPV vaccine given?
The HPV vaccine is currently given as a series of 2 injections into the upper arm.
They’re spaced at least 6 months apart, and girls can get the vaccine for free up to their 18th birthday. It’s important to have both vaccine doses to be protected.
Girls who get their first vaccination dose at the age of 15 or older will need to have 3 injections.
Men who have sex with men (MSM), and trans men and trans women who are eligible for the vaccine, will need 3 vaccination doses (2 if they’re under 15).
For those who need 3 doses of the vaccine:
- the second dose should be given at least 1 month after the first
- the third dose should be given within 12 months of the second dose
It’s important to have all vaccine doses to be properly protected.
Learn more about how the HPV vaccine is given.
How long does the HPV vaccine protect for?
Studies have already shown that the vaccine protects against HPV infection for at least 10 years, although experts expect protection to last for much longer.
But because the HPV vaccine does not protect against all types of HPV that can cause cervical cancer, it’s important that all girls who receive the HPV vaccine also have regular cervical screening once they reach the age of 25.
