One of the vital components to Gavi’s capital structure is IFFIm, the International Finance Facility for Immunisation. Launched in 2006, IFFIm issues Vaccine Bonds on the capital markets against long-term donor pledges. A powerful and award-winning financial tool, IFFIm gives Gavi access to funding when it is needed most. Vaccine Bonds have raised over US$ 6.1 billion from investors, making large volumes of funds immediately available for Gavi programmes. This saves more lives faster.
