We conducted a community-based randomized clinical trial with a wait list control group among adult Latino parents or caregivers in East and South Los Angeles. Participants completed an online demographic and baseline survey and were randomly assigned to treatment or wait-list control. Based on their preference, participants received a weekly text message or email link twice a week for four weeks (Mon and Wed at noon). Twice a week messages consisted of a short text (\<160 characters) linking participants to a 2-3 minute video (Monday) and educational text (around 500 words in length. The material was divided into weekly topics regarding the coronavirus vaccine and other topics relevant to the Latino community. Participants were also directed to reliable websites where they could access additional information and links with instructions on where to get vaccinated. Upon completing the intervention, participants completed a 1-month follow-up survey.
