In 2008, an evaluation of GAVI’s vaccine and immunization support - Evaluation of the GAVI Phase 1 performance - reported increased coverage of HepB3, Hib3 and DTP3 and increased coverage in rural areas but also a lack of cost data disaggregated by vaccine that prevented GAVI from accurately evaluating the cost effectiveness of its programs and vaccines, and an “unrealistic” reliance by GAVI on the market to reduce the cost of vaccines.[23] The same year, a study of the financial sustainability of GAVI vaccine support - Introducing New Vaccines in the Poorest Countries: What did we learn from the GAVI Experience with - found that although GAVI funding equated to $5 per infant in developing countries per year for the period 2005-10, resource need was accelerating faster than growth in financing.
