Hardbound. The Options for the Control of Influenza series started as a small meeting with a limited number of participants. However, it has today expanded into an international conference with broad appeal to both researchers and clinicians. Volume V of this series is a collection of the papers presented at the 5th International Conference held in Okinawa. As researchers unravelled the mysteries of these "new" viruses, drug companies navigated new antiviral therapies designed to treat and prevent influenza through clinical trials. The development and introduction of the neuraminidase inhibitors into the market provided us with novel and improved drugs in the control of influenza. And although its impact remains unknown, recently a live attenuated vaccine was added to the repertoire of resources to control influenza.
