This paper summarizes the 2011 revision (completed July 2012) of the WHO and UNICEF estimates of national immunization coverage (WUENIC) for select antigens. Globally, DTP3 coverage was 83% during 2011, an increase from 74% during 2000, and MCV1 coverage was 84% during 2011, an increase from 72% during 2000. Among 49 countries in Sub-Saharan Africa, 17 countries attained DTP3 coverage levels > 90% and 15 countries attained MCV1 coverage > 90% during 2011. Only eight Sub-Saharan African countries maintained DTP3 coverage levels > 90% since 2005. Although there have been enormous and increasingly successful efforts to address the global burden of vaccine preventable diseases and to improve immunization coverage, an estimated 22.4 million children were unimmunized with DTP3 globally during 2011.
