WHO/UNICEF estimates of national immunization coverage
WHO and UNICEF have reviewed data available on national immunization coverage and made country-specific estimates of immunization coverage
Estimates were made for BCG, the first and third doses of diphtheria and tetanus toxoid and pertussis containing vaccine (DTP1 and DTP3), the third dose of polio containing vaccine - either oral polio vaccine or inactivated polio vaccine (Pol3) - the first and the second doses of measles containing vaccine (MCV1 and MCV2), the third dose of hepatitis B containing vaccine (HepB3), birth dose of hepatitis B vaccine (HepBB), the third dose of Haemophilus influenzae type b containing vaccine (Hib3), the third dose of pneumococcal conjugate vaccine (PcV3), the second or third dose of rotavirus vaccine depending on number of doses recommended in national schedule (RotaC), yellow fever vaccine for countries at risk where vaccination is recommended (YFV). In 2015, estimates for the first dose of rubella containing vaccine (RCV1) and first dose of inactivated polio containing vaccine (IPV1) were added. Estimates are made from the first year data is available, except for IPV1, for which estimates started in 2015.
These estimates are based on data officially reported to WHO and UNICEF by Member States as well as data reported in the published and grey literature. Whenever possible we have consulted with local experts - primarily national EPI managers and WHO regional office staff - for additional information regarding the performance of specific local immunization services. Based on the data available, consideration of potential biases, and contributions from local experts we have attempted to determine the most likely true level of immunization coverage. Coverage data are reviewed and the estimates updated annually.
