New program aims to boost HPV vaccine uptake in teen girls
NCT ID NCT07562984
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a comprehensive program to help adolescent girls aged 9-17 and their parents make informed decisions about the HPV vaccine. The program includes educational materials, shared decision-making conversations, and reminders. Researchers will compare vaccination rates and decision-making quality between those who receive the program and those who get standard care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- behavioral intervention (education, shared decision-making, reminders)
- What this could lead to
- If successful, this could provide a practical, evidence-based program to increase HPV vaccination rates among adolescent girls.
- What could go wrong
- This is an early-stage behavioral study with 300 participants, so results may not apply broadly. The intervention may not significantly change vaccination behavior.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Female, aged 9-17 years (inclusive of 9 and 17 years old). 2. Attending pediatric \& adolescent gynecology, adolescent health clinics, or related pediatric/child healthcare clinics at the research centers; or attending vaccination clinics for non-HPV vaccinations (e.g., influenza, tetanus). 3. Has not received any dose of HPV vaccine and has no definitive plan for HPV vaccination on the day of the visit (confirmed by investigator inquiry). 4. Accompanied by at least one primary caregiver (parent or legal guardian) who can comprehend the study content and is willing to participate in shared decision-making interventions. 5. Plans to reside mostly in the region where the research center is located for the next 12 months to facilitate follow-up. 6. Caregiver provides written informed consent; adolescent provides informed consent/assent per local ethical requirements. Exclusion Criteria: 1. Previous completion of or initiation of any HPV vaccine series. 2. History of severe allergic reaction to any HPV vaccine or its main components, or assessed by a vaccinating physician as currently unsuitable for HPV vaccination. 3. Comorbid severe physical illness (e.g., severe cardiopulmonary disease, active malignancy) or severe mental disorder, judged by the investigator as unsuitable for participation or likely unable to complete follow-up. 4. Participation in other clinical studies highly related to HPV vaccination behavior intervention within the past year, which may interfere with the evaluation of this study's intervention effect. 5. Currently receiving treatment for HPV-related diseases (e.g., genital warts) where the physician considers vaccination currently inadvisable. 6. History of autoimmune diseases or tumors. 7. Other situations deemed by the investigator to affect study adherence or interpretation of results (e.g., families with extremely high mobility).
