This study uses an online panel survey to test the impact of video messages on stated likelihood of COVID-19 vaccination. Participants are recruited from the Prolific.co platform. Those who have indicated to Prolific that they have not been vaccinated will be randomly assigned to either no video message or 1 of 3 video messages created by the Vaccinate LA/USC collaborative. The key endpoint is a question about the likelihood of getting vaccinated in the next 30 days.
