Influenza Vaccine Response during the Start of a Pandemic
Report of the Second WHO Informal Consultation held in Geneva, Switzerland 21 -22 July 2016
In June 2015, the World Health Organization (WHO) held an Informal Consultation to bring together key stakeholders to address questions associated with vaccine response at the start of an influenza pandemic and, in particular, the strategic problems associated with switching from seasonal influenza vaccine production to pandemic vaccine production (switch). The 2015 Consultation clarified some of the complexities associated with the switch and identified key actions and challenges. However, several gaps remained in both knowledge and planning.
A second Informal Consultation was held by WHO in June 2016. The main goal of the 2016 consultation was to work to bridge these gaps by better understanding the complexities of the early stages of pandemic vaccine development; elaborating the principles that could guide the decision to switch; obtaining a better understanding of the evidence or data needed to support the decision-making process; and prioritizing the technical actions needed to overcome any bottlenecks in pandemic vaccine production.
