Geospatial variation in measles vaccine coverage through routine and campaign strategies in Nigeria: analysis of recent household surveys

Measles vaccination campaigns are conducted regularly in many low- and middle-income countries to boost measles control efforts and accelerate progress towards elimination. National and sometimes first-level administrative division campaign coverage may be estimated through post-campaign coverage surveys (PCCS). However, these large-area estimates mask significant geographic inequities in coverage at more granular levels. Here, we undertake a geospatial analysis of the Nigeria 2017-18 PCCS data to produce coverage estimates at 1×1 km resolution and the district level using binomial spatial regression models built on a suite of geospatial covariates and implemented in a Bayesian framework via the INLA-SPDE approach.

Reaching Never- and Incompletely-Vaccinated Children with Routine Immunization: A Proof-of-Concept Activity Using Geo-Referenced Microplans in Two Health Zones in Maniema Province, Democratic Republic of the Congo

GRID3’s geospatial mapping work in Kindu and Kibombo, Maniema Province, DRC, was central to a collaborative proof-of-concept with the DRC’s EPI Programme, CDC, and AFENET: participatory mapping and house-to-house enumeration located under-vaccinated children by locality, and GRID3’s maps then guided […]

In Equateur Province, the Democratic Republic of the Congo (DRC), health workers had been told that communities along the Lokoro River were uninhabited — too prone to flooding, too hard to reach. GRID3 settlement data said otherwise, and in 2025, […]
