GAVI has identified three indicators, each with specific targets, to measure progress against the 2011-2015 strategy's overall mission: to save children's lives and protect people's health by increasing access to immunisation in poor countries
1. Under five mortality rate
The under five mortality rate measures the probability of a child born in a specific goal year or period dying before reaching the age of five, if subject to age-specific mortality rates for that period.
The use of this indicator reflects GAVI's commitment to contributing to global and country goals related to the improvement of child health.
Under five mortality rate is a leading index of child health and overall human development.
The fourth Millennium Development Goal (MDG) aims to reduce the under-five mortality rate by two-thirds between 1990 and 2015.
This indicator is measured using population weighted estimates from the United Nations Population Division, Department of Economic and Social Affairs, World Population Prospects: The 2010 Revision for the 72 GAVI eligible countries (as of 2010).
2. Number of additional future deaths averted
Number of additional future deaths averted as a result of pentavalent, pneumococcal, rotavirus, yellow fever, meningitis A, Japanese encephalitis, Human papillomavirus, typhoid and rubella vaccination in 72 GAVI eligible countries (as of 2010).
GAVI's impact in terms of averting future deaths from vaccine preventable diseases is intertwined with many other investments and actions -- most importantly those made by the countries themselves.
This indicator measures GAVI's contribution to averting future deaths, rather than exclusively attributing a portion of the impact to the Alliance's work.
For measuring progress, data will be based on a combination of direct measurement and modelling.
3. Number of additional children fully immunised as a result of GAVI support
The total number of additional children reached with the last recommended dose of any GAVI-supported vaccine, corrected on a country-by-country basis so that children receiving multiple vaccines are not double-counted.
This indicator tracks the extent to which GAVI's mission to increase access to immunisation in poor countries is being realised.
The targets for this indicator are defined through the Strategic Demand Forecast. Performance against these targets are measured by WHO, using WHO/UNICEF coverage estimates and United Nations Population Division estimates of the size of the target population in each country.
