What is the HPV vaccine used for?

Human papillomavirus, or HPV, is a common virus spread mainly through intimate skin-to-skin contact. Some types can persist in the body and contribute to changes in cells. Vaccination prepares the immune system to recognise targeted HPV types before an infection is established.

The vaccine prevents new HPV infections; it does not clear an HPV infection that is already present, treat abnormal cervical cells, or replace cervical screening. It can be useful for people of different ages when recommended by a clinician, although the benefit is greatest before exposure to HPV.

Ask a qualified clinician whether HPV vaccination is suitable for you or your child. They can review age, previous doses, pregnancy status, immune conditions, allergies, and local recommendations before explaining the schedule.

Keep any vaccination record and attend the doses advised for your situation. A sore arm, mild fever, tiredness, or brief dizziness can occur after vaccination. Sitting for a short time after the injection can help if you tend to feel faint.

Seek urgent medical help for trouble breathing, swelling of the face or throat, widespread hives, or collapse after vaccination, as these may signal a serious allergic reaction. Contact a clinician about persistent or concerning symptoms, or if you received a dose while pregnant so they can advise on the remaining schedule.

Ask which HPV vaccine and schedule apply to you, whether a previous dose counts, and what to do if an appointment is missed. You can also ask how vaccination fits alongside cervical screening.
