Preparedness of public health laboratories for respiratory infectious diseases – EU/EEA country perspectives on lessons learned from the COVID-19 pandemic
The purpose of this study was to provide evidence on how to help public health laboratories be better prepared and more resilient to future public health challenges related to respiratory infectious diseases.
From crisis to preparedness: Lessons for Europe’s public health laboratories
A study published today shows how public health laboratories can become more resilient against future respiratory infectious diseases. The findings call for sustained capacity, better coordination and EU-level support.
New analysis indicates that vaccines greatly reduce hospitalisations for flu and COVID-19
A new modelling study from RespiCompass, the European respiratory disease modelling hub coordinated by ECDC, indicates that influenza and COVID-19 vaccination programmes markedly reduced hospitalisations among older adults across Europe in the 2024/25 season.
