Abstract
Research conducted at IHME examines the number of children receiving diphtheria, tetanus, and pertussis (DTP3) immunizations in 193 countries from 1986 to 2006. The study, Tracking progress towards universal childhood immunisation and the impact of global initiatives: a systematic analysis of three-dose diphtheria, tetanus, and pertussis immunisation coverage, reveals troubling gaps between the number of children reported by countries to be immunized and numbers based on independent surveys in countries receiving aid money from the GAVI Alliance Services Support (ISS) program.
Research findings
The researchers found that while there have been continual improvements globally in the proportion of children immunized against DTP3, this has increased only gradually over time and not to the level suggested by countries’ official reports. For example, since the launch of GAVI in 1999, officially-reported estimates showed a 9% increase in DTP3 coverage, from 81% to 90%, while survey-based estimates only showed a 4.9% increase in global coverage, from 69% to 74%, over the same period.
