How eHealth Africa is using tech to close Nigeria’s immunisation gaps

Nigeria grapples with significant gaps in immunisation coverage, with 2.1 million children under one year old, or 24% of the under-one population, unvaccinated, according to UNICEF. These children reside in remote areas, conflict zones, or areas not accurately mapped for planning. eHealth Africa, a non-profit organisation, leverages geospatial technology and digital tools to address these challenges.

By mapping settlements, identifying inaccessible communities, and optimising vaccination planning, eHealth Africa has reached over 23 million children in 205,000 settlements across Nigeria in the first half of 2026. This progress is attributed to the organisation's geospatial settlement mapping, digital campaign planning through PlanFeld, and vaccine delivery tracking.

However, the sustainability of these efforts relies on the ability of Nigerian institutions to fund, operate, and maintain the technology. eHealth Africa has developed PlanFeld, a digital tool that generates microplanning and daily implementation plans for vaccination teams, reducing the time required for planning from days to minutes.

This tool also assigns workloads to teams, preventing omissions and saving costs for the government. To ensure the accuracy of settlement information, eHealth Africa collaborates with community leaders, local government officials, and programme partners to validate data every two months, particularly important in areas affected by insecurity in northern Nigeria.
