The goal is to identify the most impactful strategies for capturing attention and enhancing effectiveness of vaccine promotion messages. This will be done using an online survey that employs remote eye-tracking and self report measures to evaluate response to sample vaccine promotion social media content in rural populations in New England. Participants will be randomly assigned into one of 14 conditions in a 2(source: expert vs. influencer) by 7 (themes: constructs from 7C Vaccine Framework) experiment and view sample messages and then answer questions about their attitudes and beliefs while being monitored for eye-tracking.
