In 2015, estimated global coverage for receipt of BCG, DTP (x3), polio (x3), and measles (x1) vaccinations by age 12 months was 84–86%.
The World Health Organization (WHO) recommends that all children have access to four vaccines, BCG, DTP, polio, and measles. The Expanded Programme on Immunization (EPI) was established by the WHO in 1974 to support routine access for children to these four vaccines, particularly in low income countries.
Using receipt of a third DTP (diphtheria/tetanus/pertussis) vaccination by age 12 months as a measure of coverage for the four routinely recommended vaccines, global coverage levels have improved from below 5% in 1974, before the EPI, to a steady 84–86% since 2010.
