Using Digital Technology to Build COVID-19 Vaccine Confidence: A Qualitative Study among Latinx Parents of Children Aged 5-11 in Under-Resourced Communities across Los Angeles County.

: Latinx school-aged children are more than twice as likely to be infected with and die from COVID-19 as non-Latinx White children in Los Angeles. Although COVID-19 vaccination has the potential to mitigate health disparities exacerbated by the pandemic, vaccination uptake among Latinx children remains limited. MiVacunaLA (MVLA) is a mobile-phone-delivered digital intervention that improved vaccination rates in 12- to 17-year-old Latinx children and parental intention to vaccinate 2- to 11-year-old children.
