Despite the growing availability of effective COVID-19 vaccines in rural communities in the United States, widespread vaccine hesitancy delays COVID-19 vaccine coverage in rural communities and threatens to worsen pre-pandemic rural-urban disparities in other vaccination rates, including influenza and routine pediatric immunizations. Therefore, there is an urgent need to develop communication-based interventions to improve vaccine confidence in rural America. This study demonstrates the efficacy of a community-engaged approach to developing social media campaign messages in promoting COVID-19 vaccine uptake and pro-vaccine social diffusion among rural adults. Using a community-engaged approach, we developed social media campaign videos varying in (a) featured messengers (clinicians versus community leaders) and (b) the presence of personal testimonials. We conducted a national online experiment (N = 1,364 rural adults) in spring 2022. We found that videos featuring clinicians serving rural communities and their testimonials increased (a) vaccination intentions in the unvaccinated group (4-point scale, b = 0.23, p =.015) and (b) intention to discuss the messages with others (4-point scale, b = 0.14, p =.037), share the message (4-point scale, b = 0.15, p =.026), and promote the vaccines to others (9-point scale, b = 0.48, p =.013). Results suggest that vaccine promotional social media campaigns targeting rural populations can benefit from including clinician testimonials.
