While some of these resources may be captured in stages 1 or 3, it is likely that not all funding is captured in this analysis. For example, the list includes the International AIDS Vaccine Initiative (IAVI), which aims to develop vaccines and other innovations for HIV prevention, and research for agricultural development and food security conducted as part of the CGIAR network. While there are other entities on the list, which also conduct research as part of their work programme, e.g. multilateral organisations, research is often not their main activity. Contributions to or through these entities are therefore not included in this analysis as it cannot be determined that all funding supports STI.
