About this study

Bundling three high-impact mHealth interventions (a digital vaccine registry (supply side), a reminder system (demand side), and targeted vaccine drive (demand and supply-side) will be feasible, acceptable, carried out with fidelity, and result in a 10% improvement in vaccine completion rates compared to the year prior to implementation.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • All parents or caregivers of patients who bring their child to the vaccine clinic to receive immunization for their first vaccine visit.

Exclusion criteria

  • Parents or caregivers not willing to participate.

Treatment and study plan

Appointment reminders, motivational interviewing and targeted vaccine drives

Behavioral

Automated and real time phone call reminders, motivational interviewing and targeted vaccine drives applied in sequence

Primary outcomes

  1. DPT3 vaccine completion rate

    Time frame: 15 Months

    The proportion of enrolled subjects who complete the Diphtheria, pertussis, and tetanus vaccine (DPT3) vaccine series when assessed at 15 months of age.

  2. Measles vaccine completion rate

    Time frame: 15 Months

    The proportion of enrolled subjects who complete the measles vaccine series when assessed at 15 months of age.

  3. Number of eligible subjects enrolled

    Time frame: 15 Months

    Vaccine clinic records will be reviewed to identify the total number of eligible patients in the clinic (defined as those presenting to the vaccine clinic with a child receiving their first vaccine) and the number who agreed to participate during the study period.

  4. Provider Adoption

    Time frame: 15 Months

    A modified intervention acceptability, perception and system usability assessment using a Likert scale questionnaire.

  5. Protocol Adherence

    Time frame: 15 Months

    The proportion of eligible subjects who received a real-time phone call reminder, counselling, and targeted vaccine drive when indicated

  6. Project Cost

    Time frame: 15 Months

    The cost of administering each component of the mHealth bundle will be documented, such as cost of targeted drive and cost of real time phone calls. This will assist in determining the cost to scale the project.
