RESUMO
Since December 2005 the GAVI Alliance (GAVI) Health Systems Strengthening (HSS) window has offered predictable funding to developing countries, based on a combined population and economic formula. This is intended to assist them to address system constraints to improved immunization coverage and health care delivery, needed to meet the Millennium Development Goals. The application process invites countries to prioritize specific system constraints not adequately addressed by other donors, and allows them to allocate their eligible funds accordingly. This article presents an analysis of the first four rounds of countries' funding applications. These requested funding for a variety of health system initiatives that reflected country-specific requirements, and were not limited to improving immunization coverage. Analyses identified a dominance of operational-level health service provision activities, and an absence of interventions related to demand and financing. While the proposed activities are only now being implemented, the results of this study provide evidence that the open application process employed by the HSS window has led to a shift in analysis and planning-from the programmatic to the systemic-in the countries whose applications have been approved. However, the proposed responses to identified constraints are dominated by short-term operational responses, rather than more complex, longer term approaches to health system strengthening.
