Do personal story and informational videos encourage older adults to get vaccinated?
Can Stories Encourage the Elderly to Vaccinate? Combining Viewer-tailored Personal Narrative Videos With Informational Videos to Improve Vaccine Uptake Among Older Adults
This project will try informational videos, personal story videos, and a mix of both to see which best increases vaccination among U.S. adults aged 50 and older.

What this trial studies
Participants aged 50 and older in the United States will be shown one of three video formats: an informational animation, a personal narrative, or a combination of both, and their subsequent vaccination behavior will be tracked. The intervention is delivered via participants' own devices and requires completion of pre- and post-viewing surveys. Recruitment and data collection are conducted in partnership with Ipsos, with Johns Hopkins Bloomberg School of Public Health as the lead sponsor and Merck collaborating. The trial compares the relative effectiveness of narrative versus informational messaging on vaccine uptake in an older adult population.
Who should consider this trial
Good fit: U.S. adults aged 50 and older who can view and listen to videos on their device and complete brief surveys are ideal candidates for this project.
Not a fit: People who cannot or will not view videos on their device, who fail to complete required surveys, or who are already firmly unwilling to be vaccinated are unlikely to benefit from participation.
Why it matters
Potential benefit: If successful, the findings could identify simple, scalable video messaging that increases vaccination rates among older adults.
How similar studies have performed: Prior communication research shows mixed but promising results for personal narratives improving vaccine attitudes, though evidence on actual uptake among older adults is limited.
