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 third dose of diphtheria and tetanus toxoid and pertussis vaccine (DTP3), the third dose of polio vaccine - either oral polio vaccine or inactivated polio vaccine (Pol3) - the first dose of measles vaccine (MCV) and the third dose of hepatitis B vaccine (HepB3). We have also made estimates of the proportion of live births protected (PAB) through maternal immunization with at least two doses of tetanus toxoid for country where the risk of neonatal tetanus is a significant public health problem for the year 2000 onward. In 2005 we added estimates of the first dose diphtheria and tetanus toxoid and pertussis vaccine (DTP1) and the third dose of haemophilus influenzae type b (Hib3), in 2010 the third dose of Pneumococcal conjugate vaccine (PcV3), second or third dose of Rotavirus vaccine depending on number of doses recommended in national schedule (RotaC), and Yellow Fever vaccine for countries at risk where vaccination is recommended, in 2014 second dose of measles containing vaccine (MCV2) and Birth dose of Hepatitis B vaccine (HepBB) and in 2015 revision we included first dose of Rubella containing vaccine (RCV1) and first dose of inactivated polio vaccine (IPV1) if the country was using oral polio vaccine 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.
