HPV prevention: vaccination and cervical screening work together

What the latest vaccine discussion means

WHO’s 29 October 2026 immunization update reports that its expert advisory group reviewed HPV vaccine evidence earlier in the month and supported a single-dose approach for girls aged 9–14 as an efficient way to expand protection.

This is international policy advice, not an instruction to change an individual course. Eligibility, products and schedules depend on your country and circumstances, and people with weakened immune systems may need additional doses. Check your records with the local vaccination service before assuming you are finished or need to restart.

HPV is common; persistence is what matters

Human papillomavirus, or HPV, is a group of viruses. Most infections clear naturally, but persistent infection with certain high-risk types can lead to changes in cervical cells. Those changes are not the same as cancer, and identifying them can provide an opportunity for follow-up and treatment.

The cervix is the lower part of the womb. A person can have HPV without knowing it. A test result cannot reliably tell when infection started, so a positive result is not proof of a recent infection or a partner’s behaviour.

Vaccination and screening do different jobs

HPV vaccination helps prevent infection with targeted HPV types; it is not a treatment for an existing infection. Cervical screening looks for high-risk HPV or cell changes, depending on the programme, so that concerning findings can be assessed.

Vaccinated people still need the screening recommended for them. Starting ages, intervals, sampling methods and follow-up vary across countries and with medical history. Use your national service’s advice rather than copying a schedule from an overseas website. Ask your clinician if you have a weakened immune system, previous abnormal results or uncertainty about whether you need screening.

A positive result needs a plan, not a diagnosis online

Finding high-risk HPV does not by itself diagnose cervical cancer. Some results lead to repeat testing; others require an examination of the cervix called colposcopy. What happens next depends on the test and whether abnormal cells were found.

Read the full result letter and keep its follow-up date. If the wording is unclear, ask the screening service to explain the result and who will arrange the next appointment. If results have not arrived when expected, contact the service rather than assuming no news means no action is needed.

Make the appointment manageable, and act on symptoms

Bring previous results and vaccine records if available. Ask what the test involves, when to expect the result and how to request support if examinations are painful or difficult. Tell the professional about relevant health conditions and concerns; you can ask questions before agreeing to a test.

Unusual bleeding, including after sex or after menopause, persistent pelvic pain or a change in discharge deserves medical assessment. These symptoms can have several causes. Do not wait for routine screening, or use a previous normal result to dismiss a continuing change. For heavy bleeding with fainting or severe illness, seek urgent help.
