Conectados: Social Networks and Social Media for Vaccine Uptake

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.
