The economic challenges of new drug development()

The COVID-19 pandemic has witnessed highly successful efforts to produce effective vaccines and treatments at an unprecedented pace. This perspective discusses factors that made this possible, from long-term investments in research infrastructure to major government interventions that absorbed much of the risk from research and development. We discuss key economic obstacles in the discovery of new drugs for infectious diseases, from novel antibiotics to diseases that primarily affect the poor. The world's collective experience of the pandemic may present an opportunity to reform traditional economic models of drug discovery to better address unmet needs. A tax-funded global institution could provide incentives for drug discovery based on their global health impact. International co-operation would be needed to agree and commit to adequate funding mechanisms, and the necessary political will would require strong public support. With the current heightened appreciation of the need for global health system resilience, there may be no better opportunity than now.
