Intervention model description: In collaboration with community partners, we designed mivacunaLA as an RCT with a wait-list control group to ensure that all participants could benefit from the educational intervention. The treatment group received the 1 month intervention upon enrollment and the wait-list control received the intervention at month 2 from enrollment. We propose to analyze baseline data for the primary outcomes related to adult caregiver behaviors regarding COVID-19 vaccination for children living in the household for 1 month outcomes, before the control group was exposed to the intervention.
Primary purpose: PREVENTION

Brief summary: The aim of this study is to determine whether a community-informed, linguistically and culturally tailored educational program delivered via mobile phone is effective in improving vaccination behaviors among Latino families. Thus we evaluate a community-based mobile phone intervention (mivacunaLA) to assess if there is an increase in vaccination rates among 12-17 year old children and willingness to vaccinate 2-11year old children who have not been previously vaccinated who reside in high-risk and low resourced neighborhoods in Los Angeles.

Detailed description: 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.
