MiVacunaLA: an Intervention to Improve COVID-19 Vaccination Behaviors Among Latinos
Condition: COVID-19 Pandemic
MeSH terms: COVID-19
Study type: Interventional

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.
    

Intervention name(s): mivacunaLA
Intervention type(s): Behavioral
Intervention description(s): 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.
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.
