A mid-term assessment of progress towards the immunization coverage goal of the Global Immunization Vision and Strategy (GIVS)

Abstract

BackgroundThe Global Immunization Vision and Strategy (GIVS) (2006-2015) aims to reach and sustain high levels of vaccine coverage, provide immunization services to age groups beyond infancy and to those currently not reached, and to ensure that immunization activities are linked with other health interventions and contribute to the overall development of the health sector.ObjectiveTo examine mid-term progress (through 2010) of the immunization coverage goal of the GIVS for 194 countries or territories with special attention to data from 68 countries which account for more than 95% of all maternal and child deaths.MethodsWe present national immunization coverage estimates for the third dose of diphtheria and tetanus toxoid with pertussis (DTP3) vaccine and the first dose of measles containing vaccine (MCV) during 2000, 2005 and 2010 and report the average annual relative percent change during 2000-2005 and 2005-2010. Data are taken from the WHO and UNICEF estimates of national immunization coverage, which refer to immunizations given during routine immunization services to children less than 12 months of age where immunization services are recorded.ResultsGlobally DTP3 coverage increased from 74% during 2000 to 85% during 2010, and MCV coverage increased from 72% during 2000 to 85% during 2010. A total of 149 countries attained or were on track to achieve the 90% coverage goal for DTP3 (147 countries for MCV coverage). DTP3 coverage ≥ 90% was sustained between 2005 and 2010 by 99 countries (98 countries for MCV). Among 68 priority countries, 28 countries were identified as having made either insufficient or no progress towards reaching the GIVS goal of 90% coverage by 2015 for DTP3 or MCV. DTP3 and MCV coverage remained < 70% during 2010 for 16 and 21 priority countries, respectively.ConclusionProgress towards GIVS goals highlights improvements in routine immunization coverage, yet it is troubling to observe priority countries with little or no progress during the past five years. These results highlight that further efforts are needed to achieve and maintain the global immunization coverage goals.
