To investigate indirect vaccine effectiveness (indirVE) of vaccination of children and adolescents with seasonal influenza vaccines against influenza-related outcomes occurring in other population groups.

Human influenza A viruses escape antibody-mediated immunity through changes in the hemagglutinin (HA) and neuraminidase (NA) glycoproteins.

A new modelling study from RespiCompass, the ECDC Respiratory Diseases Scenario Modelling Hub, indicates that influenza and COVID-19 vaccination programmes markedly reduced hospitalisations among older adults across Europe in the 2024/25 season.

The Society has published a Clinical Consensus Statement in the European Heart Journal highlighting the key role of vaccination in preventing cardiovascular events.

Immune responses against neuraminidase (NA) and hemagglutinin (HA) are critical for developing effective influenza vaccines, yet their role in influenza transmission remains unclear.

In partnership with ESWI, the Coalition for Life Course Immunisation has released a new policy brief highlighting the urgent need for a more coordinated, life-course approach to respiratory virus prevention across the EU.

Annual influenza epidemics in the United States cause hundreds of thousands of hospitalizations.
