Addressing HPV Vaccine Hesitancy by Co-Designing a Digital Health Intervention

100 participantsStarted 2026-08

Plain-language summary

This study looks at a digital platform that supports HPV vaccination in schools. The goal is to see if it is useful, easy to use, and practical in real school settings, especially in areas where fewer people get vaccinated. Researchers will give Year 5 pupils (aged 11-12) and their parents or caregivers access to the platform. It provides clear, trusted information about the HPV vaccine for young people, parents, and school nurses. The aim is to make the vaccine easier to understand and to help answer any questions or concerns. After using the platform, participants will be asked to share their thoughts.

We will aim to recruit 6-8 compulsory schools in Stockholm County to serve as clusters. All Year 5 pupils and their caregivers in the study schools are invited. Inclusion Criteria: * The school provides education to pupils in school year 5 and is scheduled to be open throughout the pilot trial period * The school is located in an area with HPV vaccine uptake \<85.2% (the Stockholm regional average) * The head principal and school nurse both consent to participate * The school has the capacity to implement the intervention Exclusion Criteria: * Failure to meet the inclusion criteria

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
