Phone calls could save lives: new study tests vaccine reminders for displaced kids
NCT ID NCT07154836
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether automated phone call reminders can help increase childhood vaccination rates among internally displaced families in Borno State, Nigeria. About 366 caregivers of young children will receive regular calls with reminders and health info in local languages. Researchers will measure how many children get vaccinated and how well the system works in a conflict-affected, low-resource setting.

- What this could lead to
- If it works, this could provide a low-cost way to increase vaccination coverage in hard-to-reach, conflict-affected areas.
- What could go wrong
- This is a small feasibility study, not a large trial. Results may not apply to other settings, and phone access or network issues could limit effectiveness.
