Using Tailored Personal Stories and Informational Videos to Encourage Vaccination Among Adults 50 and Older

What this Trial Is About

Researchers are evaluating the impact of different types of videos on increasing vaccination rates among older adults. This study compares the effectiveness of informational animation videos, personal narrative videos, and combinations of both in encouraging vaccination. The focus is on U.S. adults aged 50 and older, aiming to understand which video approach better motivates vaccine uptake. Participants are randomly assigned to one of five groups no videos, informational animation video only, personal narrative video only, personal narrative video followed immediately by the informational animation video, or informational animation video followed immediately by the personal narrative video. The informational animation covers human papillomavirus HPV disease, addresses specific concerns, and explains the safety and importance of HPV vaccines. Personal narrative videos share individual experiences with HPV and are tailored to match each participants raceethnicity and gender as closely as possible. During the study, participants will be followed for 9 months to track how many receive the vaccine after viewing the assigned videos or no videos. Researchers will measure vaccine uptake as the primary outcome. Participants need to complete surveys and be able to watch and listen to videos on their devices. The study is sponsored by Johns Hopkins Bloomberg School of Public Health and includes healthy volunteers aged 50 and older.
