What this trial studies

This cluster-randomized controlled trial in Ghana's Oti Region will test a biometric-linked digital vaccination record system to improve completion of the four-dose malaria vaccine and routine infant immunizations. Participating health facilities will use Simprints' biometric IDs to automatically identify children who are behind schedule and guide health worker outreach, while caregivers receive automated voice-message reminders. Pregnant women in their last two trimesters and mothers of infants under six months who remain in the area and consent will be enrolled, with randomization at the community or facility level. The primary outcome is the proportion of children completing malaria and routine vaccination schedules, measured through the digital records and health service data.

Who should consider this trial

Good fit: Ideal candidates are pregnant women in their second or third trimester or mothers of infants under six months, aged 15–49, who plan to stay in the area for at least 12 months and provide consent.

Not a fit: Men, non-emancipated minors, women outside the 15–49 age range, people who plan to move away within 12 months, those who do not consent, and children already fully vaccinated are unlikely to benefit from joining.

Why it matters

Potential benefit: If successful, the system could raise vaccine completion rates and lower malaria illness, hospitalizations, and deaths among young children.

How similar studies have performed: Automated reminders have improved vaccination adherence in other settings, but biometric-linked systems for childhood vaccine completion are relatively novel and less widely tested.
