Trends in immunization coverage (global and regional)
DPT refers to the combined diphtheria, pertussis and tetanus vaccine. The percentage of children receiving the third dose of DPT (DPT3), is an indicator of how well countries provide routine immunization services.
Global coverage for DPT3 has slowly but steadily increased to 83 per cent in 2011, a remarkable improvement from 20 per cent in 1980

Regional coverage for DTP3 (1980-2011)
While global coverage for DPT3 (three doses of the combined diphtheria/pertussis/tetanus vaccine) has been steadily climbing from 73 per cent in 2000 to 83 per cent in 2011, improvements have been modest in recent years. In fact, in 2011, DTP3 coverage increased only in Eastern and Southern Africa. Out of the eight global regions, four showed no change in coverage and three showed declines. While the declines in Latin America and South Asia are negligible, coverage in the Western and Central Africa region dropped precipitously from 70 to 62 per cent. This deterioration was driven by sharp declines in coverage in such countries as Nigeria, Côte d’Ivoire and Chad.
