Education, Immigration and HPV Vaccination: an Informational Randomized Trial

Sweden2,500 participantsStarted 2021-04-28

Plain-language summary

Counteracting misinformation on childhood vaccines remains a priority for public health in industrialized countries. Previous research showed that misinformation-induced vaccine hesitancy particularly concerns very highly or very lowly educated parents, and, especially in Europe, specific groups of immigrants. Misinformation framing directly targets specific sub-population of parents by exploiting different cognitive biases, and specific concerns based on cultural norms: this project aims at testing the effectiveness of similar framing techniques applied to positive information on the HPV vaccine by conducting a Randomized Controlled Trial in Stockholm, Sweden. It randomizes emotionally and scientifically/statistically framed information addressing the specific concerns reported by previous literature.

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.

What they're measuring

Actual decision to vaccinate child against HPV

Timeframe: From treatment administration: 8 to 18 weeks, depending on when the single subject has read the information from the behavioral intervention

(Short Term) Posterior beliefs about false risks of the HPV vaccine

Timeframe: Same day as treatment in the first survey: ~1 hour post treatment

(Long Term) Posterior beliefs about false risks of the HPV vaccine

Timeframe: Assessed in the endline survey: from treatment, 8 to 18 weeks, depending on when the single subject has read the information from the behavioral intervention
