HPV vaccine: who should get it, at what age, and how many doses?
The HPV vaccine protects against the HPV types that most often cause disease. It works best when given before exposure to the virus (at a young age), but it can also be considered up to a certain age and, in some situations, in adults. The vaccine does not treat an existing infection and does not replace screening. Eligibility, number of doses and timing vary from person to person; discuss them with your doctor.
This page answers the most common questions about the HPV vaccine — who, at what age, how many doses and special situations — to help you discuss it with your doctor. The decision to vaccinate is always an individual one.
What is the HPV vaccine and what does it do?
The HPV vaccine aims to build immunity against the HPV types that most often cause disease. This makes it possible to largely prevent the genital warts and certain precancerous changes caused by these types.
Two important points: the vaccine does not treat an existing infection and does not replace screening. It works best when given before exposure to the types it covers.
Which types does it protect against?
The current HPV vaccine (9-valent) targets the most important types, both those that cause warts and those linked to cancer: 6, 11, 16, 18, 31, 33, 45, 52 and 58. In other words, it aims to protect not against a single type but against a group of the types that most often cause problems.
Who is it recommended for?
- It is recommended for girls and boys, usually before or in early adolescence (for the greatest effect).
- It is also considered, up to a certain age, for teens and young adults who did not get vaccinated on time.
- For older adults, the benefit is individual, so the decision is made through a conversation between doctor and patient.
How many doses are needed?
The number of doses depends on age and health status:
| Situation | General dosing schedule |
|---|---|
| First dose given before age 15 | 2 doses |
| Started at age 15 or older | 3 doses |
| People with a weakened immune system | 3 doses |
This is a general framework; your doctor will set the exact schedule and intervals that are right for you.
Can people who are HPV positive or married get vaccinated?
- People who are HPV positive: The vaccine does not treat an existing infection, but it may protect against other types you have not been exposed to; so it may be considered.
- People who have had genital warts / are married / are sexually active: Because you may not have been exposed to all the types the vaccine covers, it may still be useful.
In every case, eligibility is individual and should be discussed with a doctor.
After age 26, pregnancy and breastfeeding
Ages 27–45: The vaccine can also be given at these ages; however, because the benefit varies from person to person, the decision is made individually through a conversation between doctor and patient.
Pregnancy: The HPV vaccine is not recommended during pregnancy. If you are planning a pregnancy, discuss the timing with your doctor.
Breastfeeding: Ask your doctor about eligibility while breastfeeding.
Do you still need a Pap test after vaccination?
Yes. This is one of the most common misconceptions. The vaccine covers the most common types, but not all of them. That is why vaccinated people continue with the recommended screening program. Vaccination and screening together provide the strongest protection.
Side effects and safety
The most common side effects are temporary and mild: pain, redness or swelling at the injection site, mild fever, headache or tiredness. These usually pass quickly.
Serious side effects are rare. A short observation period after vaccination may be recommended (because of rare fainting). Share any concerns about your own health with your doctor before vaccination.
How and where to ask
To find out whether the HPV vaccine is right for you, what dosing schedule applies and how to obtain it, you can consult an obstetrician-gynecologist or, in Türkiye, your family health center (aile sağlığı merkezi). Eligibility and timing are planned individually.
The vaccine is a strong part of prevention — but not on its own: it works best together with regular screening. The decision always rests with you and your doctor.
Frequently asked questions
How many doses of the HPV vaccine are given?
The number of doses depends on age and health status: usually 2 doses for people who start before age 15, and 3 doses for those who start at 15 or older or who have a weakened immune system. Your doctor will set the exact schedule.
Can the HPV vaccine be given after age 26?
The vaccine is most effective at a young age. For adults aged 27–45, the benefit varies from person to person, so the decision is made individually through a conversation between doctor and patient.
Can I get vaccinated if I'm HPV positive?
The vaccine does not treat an existing infection, but it may protect against other types you have not yet been exposed to. For this reason, it may be considered in some cases for people who test positive. Talk to your doctor about whether it is right for you.
Does the HPV vaccine protect against cancer?
The vaccine targets the types responsible for most HPV-related cancers and contributes substantially to preventing these cancers. Even so, because it does not cover all types, screening continues to be recommended.
Should I have a Pap test after getting vaccinated?
Yes. The vaccine covers the most common types but not all of them, so vaccinated people continue with the recommended screening program.
Can the HPV vaccine be given during pregnancy?
The HPV vaccine is not recommended during pregnancy. If you are planning a pregnancy or breastfeeding, discuss the timing with your doctor.
Can married or sexually active people benefit from the vaccine?
They can. A person may not have been exposed to all the types the vaccine covers, so it may still offer protection. Eligibility is assessed with a doctor based on age and circumstances.
What are the side effects of the HPV vaccine?
The most common are temporary, mild effects such as pain and redness at the injection site, a mild fever or a headache. Serious side effects are rare. Talk to your doctor about any concerns.
