Improving Pediatric COVID-19 Vaccine Uptake Using an mHealth Tool (MoVeUP)

February 19, 2025 updated by: IDeA States Pediatric Clinical Trials Network

Improving Pediatric COVID-19 Vaccine Uptake Using an mHealth Tool: a Randomized, Controlled Trial

This study will determine the effectiveness of a vaccine communication mobile health app on parental decisions to vaccinate their children against coronavirus disease 2019 (COVID-19).

The hypothesis is that unvaccinated children of caregivers assigned to the Vaccine Uptake app will be more likely to achieve COVID-19 vaccine series completion than those children whose caregivers are assigned to the General Health app.

Study Overview

Detailed Description

This is a site-level block-randomized trial. The study population is Custodial parents/caregivers with ≥1 child eligible for COVID-19 vaccination who has not yet received the vaccine at the time of study enrollment.

The primary objective is to determine the effect of a parent-facing, vaccination decision-making mobile health (mHealth) tool on children's COVID-19 vaccine series completion. The endpoint of this objective is the proportion of children who complete COVID-19 vaccination, as verified in state, clinic, or participant-held records.

Secondary Objective 1 is to determine the effect of a parent-facing, vaccination decision-making mHealth tool on children's COVID-19 vaccine series initiation. The endpoint of this objective is the proportion of children who receive ≥1 dose of the COVID-19 vaccination series, as verified in state, clinic, or participant-held records

Secondary Objective 2 is to determine the effect of a parent-facing, vaccination decision-making mHealth tool on parental attitude toward pediatric COVID-19 vaccination. The endpoint of this objective is the change in enrolled parent/caregiver domain scores from baseline to week 16 on the modified World Health Organization (WHO) Strategic Advisory Group of Experts on Immunization (SAGE) Vaccine Hesitancy Scale adapted for the COVID-19 Vaccine.

Enrolling sites will recruit participants. These sites will collaborate with outpatient practices within Environmental influences on Child Health Outcomes (ECHO) Institutional Development Award (IDeA) States Pediatric Clinical Trials Network (ISPCTN) states that provide primary care services to children (<18 years old). Sites will serve a population base of at least 40% Medicaid/uninsured children, <60% non-Hispanic White children, or >40% of families residing in rural communities. Sites are encouraged, but not required, to have a high Spanish-speaking population.

Study interventions are a Vaccine Uptake App and General Health App. The Vaccine Uptake App will include 24-week (8 weeks with weekly push notifications; 2 monthly push notifications for 2 months [1 notification per month]; 8 weeks without) exposure to a mobile phone application (app) designed to improve parental knowledge, attitudes, and self-efficacy regarding pediatric COVID-19 vaccination. The app will address logistical and motivational barriers to pediatric COVID-19 vaccination. Participants will also receive eight weekly nudges and 1 monthly nudge for 2 months (cues to action) regarding vaccinating their child that will be sent to participants via push notifications to their mobile devices. Through branching logic, users will access content tailored to their COVID-19 vaccine knowledge and confidence gaps, locality, degree of rural-urban primary residence, primary language (English/Spanish), race/ethnicity, and child's age.

The General Health App will include 24-week (8 weeks with weekly push notifications; 2 monthly push notifications for 2 months [1 notification per month]; 8 weeks without) exposure to a mobile phone app designed to provide information on general pediatric health and infection prevention and mitigation strategies based on recommendations from the American Academy of Pediatrics (AAP) and the Centers for Disease Control and Prevention (CDC). Nudges regarding these topics will be sent to participants via push notifications to their mobile devices.

The study duration is 24 months (6 months study start-up; up to 8 months rolling enrollment; 7 months final participants' completion; 3 months analysis). Participant duration is 27 weeks.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of Children Who Complete COVID-19 Vaccination, as Verified in State, Clinic, or Participant-held Records
Time Frame: Week 24
Initiation and completion of the COVID-19 vaccine series during the 24-week intervention period. Vaccine series completion will be per ACIP guidance for the vaccine product. For children who receive a product that requires more than 2 doses for the primary series, receipt of up to 3 doses will be considered complete. Vaccine doses will be valid if given within 24-week study intervention. Additional doses for primary series completion will be valid if they are in accordance with ACIP-recommended interval minus a 4-day grace period. There will be no maximum interval between valid doses. An incorrect second vaccine product (i.e., mixed series) will be invalid. The statistical team will use a mixed model with the binomial distribution and the logit link to compare the two intervention groups and the proportions of children who complete COVID-19 vaccination, using a site random effect and controlling for clustering by caregiver.
Week 24

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of Children Who Receive ≥1 Dose of the COVID-19 Vaccination Series, as Verified in State, Clinic, or Participant-held Records
Time Frame: Week 24
For each vaccine-eligible child, this secondary endpoint will be defined as whether or not the child initiates the COVID-19 vaccine series during the 16 weeks of study participation. Vaccine series initiation will be receipt of at least 1 valid dose of any COVID-19 vaccine product. Vaccine doses for series initiation will only be valid for study purposes if given within the 16 weeks of study participation. The statistical team will use a mixed model with the binomial distribution and the logit link to compare the two intervention groups with respect to the proportions of children who initiate COVID-19 vaccination, using site as a random effect and controlling for clustering by caregiver.
Week 24
Change in Enrolled Parent/Caregiver Domain Scores From Baseline to Immediately Post-intervention on the Modified WHO SAGE Vaccine Hesitancy Scale Adapted for the COVID-19 Vaccine
Time Frame: 16 weeks

The Strategic Advisory Group of Experts on Immunization (SAGE) working group on vaccine hesitancy developed a vaccine hesitancy measure, the Vaccine Hesitancy Scale (VHS). The study team will evaluate parental attitude toward pediatric COVID-19 vaccination by using the vaccine hesitancy questionnaire that includes ten statements with ordinal responses using a 5-point Likert scale (1=strongly disagree,...,5=strongly agree).

A composite vaccine hesitancy score was computed based on the sum of the 10 items after reverse coding items 1, 2, 3, 4, 6, 7, and 8 (range of 10 to 50). The reverse coding allowed for directionality uniformed across the 10 items; therefore, higher composite score indicated more hesitancy overall. We report summary statistics including means and standard deviation at baseline and week 16. A linear mixed mode was used to account for parent/caregivers nested within clinics and allow adjustment for baseline SAGE composite score.
