The GAVI Alliance has been providing support to the world's poorest countries since 2000 so that they can increase their access to immunisation.
GAVI has approved a total of US$ 3.7 billion to countries for the period 2000 to 2015 (as at August 2008).
When an application from a country is approved for fundiing, the country is given an estimate of the total amount of multi-year GAVI financial support. For each year of support this estimate is recalculated according to revised immunisation targets, outlined in the country’s annual progress reports.
