Scientists have predicted that another pandemic is likely. They've identified the viruses that might cause it—although the Department of Health and Human Services told us that few antiviral drugs for those viruses have been approved or are in HHS-funded clinical trials. Our panel of experts suggested several ways for policymakers to incentivize the development of these antiviral drugs, such as research grants or commitments to buy the drugs once they're approved. This report covers incentives and policy options to help develop antiviral drugs now, should policymakers want to invest in these drugs to prepare for a future pandemic.
