Developing these vaccines requires investment.
However, evidence on what it would cost to successfully develop a sound epidemic infectious disease vaccine portfolio is scarce.
This is partly because of a paucity of explicit, publicly available cost data. In addition, there is little agreement across global vaccine development funders on which epidemic infectious disease investments should be prioritised, which stems from an absence of global research and development portfolio strategy and coordination.
Crimean Congo haemorrhagic fever, chikungunya, Ebola, Lassa, Marburg, Middle East respiratory syndrome coronavirus, Nipah, Rift Valley fever, severe acute respiratory syndrome, severe fever with thrombocytopenia syndrome, and Zika. WHO has now updated this list,
however all 11 diseases remain of considerable epidemic preparedness importance.
