Preparedness session: Are we “PRET” for the next pandemic?

24 Nov 2023
World Health Organisation, Health Emergency Program (WHE/WHO)

Are we ready for the next pandemic? This session will focus on what we can do to be better prepared.

The session will start with a reflection exercise: what did we learn from the COVID-19 pandemic and how will it impact future pandemic preparedness?

WHO will then present its new initiative ‘PRET: Preparedness and Resilience for Emerging Threats’ to engage and inform participants about the innovative mode of transmission approach for pandemic planning. Examples for pathogen-specific elements such as influenza will be highlighted and discussed. Ways to engage in PRET will be shared.

The session will end with participant inputs and hearing from those engaged in pandemic planning to share their experiences.

Date and time

Friday, 24 November, 15.30 - 16.15 CET
