What to expect from HPV vaccination for genital warts

Genital warts are caused by certain types of human papillomavirus. Vaccination trains the immune system to recognise covered HPV types before exposure; it does not clear HPV that is already present and does not directly shrink established warts. A person with genital warts may still be offered vaccination when it is appropriate, because previous exposure to one type does not necessarily mean exposure to every type covered by the vaccine.

The clinician will review age, health history, allergies, pregnancy status, prior doses, and the recommended schedule for you. The injection is given in the upper arm. A sore arm, tiredness, headache, or a mild fever can occur for a short time. Protection is not immediate, and vaccination does not replace safer-sex practices or examination of new lesions.

Bring details of previous HPV doses and tell the vaccinator about a severe reaction to a vaccine, current illness, or medicines that affect immunity. Sit for observation after the injection if advised, drink fluids, and use simple comfort measures for a sore arm. Continue recommended screening and use condoms or other barrier methods, remembering that these reduce but do not eliminate HPV transmission.

Existing warts may need separate treatment, such as a prescribed cream, freezing, or a procedure. Do not apply household wart removers to genital skin.

Seek urgent help for breathing difficulty, facial or throat swelling, widespread hives, fainting that does not quickly settle, or severe dizziness after vaccination. Arrange a genital-health review for bleeding, ulceration, severe pain, rapidly changing lesions, difficulty passing urine, or a diagnosis that has not been confirmed.

Ask which HPV types the vaccine covers, how your previous exposure affects the expected benefit, which doses you need, and what separate treatment or testing is suitable for existing warts.
