MiVacunaLA: an Intervention to Improve COVID-19 Vaccination Behaviors Among Latinos

Purpose

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.

Study Design

Phase: N/A
Study Type: Interventional
Allocation: Randomized
Intervention Model: Crossover Assignment
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
Masking: Single (Outcomes Assessor)
Masking Description: Participants were informed at enrollment what arm they belonged to. Investigators could see what arm participants were assigned to. Outcome assessors/data analysts was blinded.

Arm Groups

Arm	Description	Assigned Intervention
Experimental Treatment received intervention at enrollment	Participants received mobile phone delivered intervention at enrollment. The intervention had a duration of 4 weeks. Each week participants received two text messages inviting them to view a short video (Monday) and brief written content (Wed). Each week, the material consisted of a culturally tailored theme related to COVID-19 vaccination. Participants also received information on how to get vaccinated.	Behavioral: mivacunaLA Based on their stated language preference in the baseline survey, eligible participants in the program received a text message or email twice a week (Monday and Wednesday at noon). The short text messages (<160 characters in length) provided a link to a 2-3 min video (Monday) and a short educational content around 500 words (Wednesday). Content was organized by week with the following topics: 1) what is COVID-19 and how COVID-19 vaccines works, 2) COVID-19 vaccine myths and facts, 3) COVID-19 vaccine safety and efficacy in children, and 4) how to obtain COVID-19 vaccines in your community. Every week we provided information about how to get vaccines with links to local vaccine sites & resources.
Other Control	Wait-list control. No intervention during month 1. Received the intervention at Month 2. Each week, during the first month, participants received a text with a count down of how many days were left to begin the intervention.	Behavioral: mivacunaLA Based on their stated language preference in the baseline survey, eligible participants in the program received a text message or email twice a week (Monday and Wednesday at noon).

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.
