HPV Vaccination

HPV vaccination helps prevent new HPV infections before exposure, but it does not treat an HPV infection already present.

The vaccine trains the immune system to recognise selected types of human papillomavirus. HPV spreads through intimate skin-to-skin contact, and vaccination can reduce the chance of infection with the types covered by the vaccine. It does not replace cervical screening or safer-sex measures.

You usually will not feel a noticeable difference after vaccination because its purpose is prevention rather than relief of symptoms. Protection develops as the immune system responds, and the recommended schedule may involve more than one dose.

Common short-term effects include soreness, redness or swelling where the injection was given, along with tiredness, headache or a mild fever. Sitting for a short time after the injection can help if you feel light-headed. Seek urgent help for trouble breathing, facial swelling or widespread hives after any vaccine.

HPV vaccination is a course of injections rather than a daily medicine. The number and timing of doses depend on your age when vaccination starts, your immune health and local guidance. A clinician can check your record and tell you when the next dose is due.

Vaccination works best before exposure to HPV, but some people may still be offered it later. It cannot clear existing HPV, genital warts or abnormal cervical cells. Continue recommended cervical screening after vaccination.

Routine vaccination is commonly offered to children and young people, with catch-up vaccination considered for some older people. Adults who have not been vaccinated may discuss potential benefit with a clinician. Tell the vaccinator about a previous severe allergic reaction, pregnancy, significant illness or medicines that affect immunity.

A healthcare professional reviews your health history and previous doses, explains the schedule, and gives the vaccine into an upper-arm muscle. You may be observed briefly afterwards. Keep your vaccination record so future doses can be timed correctly.

Most people return to ordinary activities soon after vaccination. The injection site may remain tender for a short time. Rest, fluids and a cool compress can make local discomfort easier to manage; use medicines only as advised for you.

Vaccines can cause reactions, and severe allergic reactions are uncommon but require immediate care. Delay or individual advice may be needed during an acute illness or pregnancy. HPV vaccination does not cause HPV infection. Tell the clinic about allergies and previous vaccine reactions before receiving a dose.

Cervical screening can find cell changes even when you have been vaccinated. Condoms and dental dams reduce but do not eliminate HPV transmission because uncovered skin can carry the virus. Vaccination and screening serve different purposes.

You can read more about the vaccine itself in HPV Vaccine, and about the infection and one possible presentation in HPV Infection and Genital Warts.

Look for a licensed vaccination clinic, primary-care service or gynaecology practice that can review your records and provide follow-up doses. Bring your immunisation history, allergy details and a list of regular medicines. Ask which vaccine schedule applies to you and how screening should continue.
