The COVID-19 pandemic has underscored the need for better tracking and monitoring domestic and international investments in health, including on pandemic preparedness. The total official support for sustainable development (TOSSD) framework can help, as it captures both cross‑border flows to developing countries, such as international assistance, and domestic contributions to global public goods, such as pandemic preparedness. This pilot study tests the current TOSSD methodology for tracking the global financing for health, and explores how TOSSD can be shaped to best respond to the emerging information needs of the international community.
