In November 2006 the Royal Society and Academy of Medical Sciences published the report Pandemic influenza: science to policy. On 27 November 2007 a one day follow-up symposium was held, which brought together academics, policy makers and other stakeholders to discuss the progress which has been made since the time of the original report. This report summarises the key issues which were raised in the presentations and discussions on areas including international avian influenza surveillance and avian vaccines; antiviral drugs and resistance; human vaccines; epidemiology and social science; and science, communication and policy.
