Nigeria has the twelfth highest under-five mortality rate in the world, with 143 child deaths per 1,000 live births in 2010. Approximately one in four of those deaths are preventable through routine immunization (RI), but coverage of routine childhood vaccines remains lower than global benchmarks and, in many parts of Nigeria, is among the lowest in the world.
Nonetheless, the Nigerian government and her partners have succeeded in acheiving major improvements in coverage rates over the past three years. National DPT3 coverage rates have improved steadily, reaching approximately 69% in 2010 according to WHO best estimates. However, this overall progress occurs in the context of significant heterogeneity at the state level and an overall coverage rate below the regional average; the need for improved systems remains apparent.
