Summary

This study is testing different ways of sharing a short, community-informed video about flu and COVID-19 vaccines to see how people respond to it. The video was created with input from Indigenous community members in California and provides information to support vaccine decision-making. Participants may see the video in one of three ways: through a paid advertisement on social media, from a trusted community organization, or from someone they know personally. After watching the video, viewers will be asked to answer one question about how much they trust it, and they may choose to complete a short survey about their vaccine views and how they received the video. The goal is to understand how trust in vaccine information changes depending on who shares it, and to improve the way health messages are delivered to Indigenous and other underserved communities.

Interventions

BEHAVIORAL

Vaccine Information Video Dissemination

The intervention is a brief, community-informed educational video (2-3 minutes) focused on seasonal flu and COVID-19 vaccination. The video was developed using human-centered design and community-based participatory methods with Indigenous community members in California. It aims to promote trust in vaccines by presenting clear, culturally relevant health information. The video is disseminated using three behavioral delivery strategies: (1) paid advertisements on Facebook and Instagram targeting adults in California, (2) peer-to-peer sharing by participants who previously enrolled in the study and are invited to serve as "seeds" who share the video with their personal contacts, and (3) distribution by trusted community-based organizations (CBOs) using their existing communication networks, including WhatsApp, social media, email, and newsletters. All viewers are prompted to complete a one-question trust poll and invited to participate in an optional anonymous survey on vaccine attitud
