Traditionally, the development of influenza products have focused on two axes: classic vaccines for disease prevention, and antiviral products for the treatment or prophylaxis of clinical influenza.

This article discusses the current challenges when developing new influenza compounds and potential regulatory avenues that could support novel therapies.
