Summary

This study evaluates the feasibility and preliminary impact of Call for Life, an mHealth platform aimed at increasing childhood vaccination coverage among internally displaced persons in Borno State, Nigeria. The platform uses an interactive voice response (IVR) system to deliver automated vaccination reminders, follow up on reported side effects, and provide health messages in English and local languages. A mixed-methods design is used to assess feasibility, interaction rates, and early effects on vaccine uptake. Findings will inform policymakers and humanitarian actors on the potential of mobile technology to strengthen immunization delivery in conflict-affected, resource-limited settings.
