This report collects all COVID-19 long-term care facilities (LTCF) data reported to ECDC from 2021 and concludes the EU/EEA LTCF COVID-19 specific surveillance data collection from 2021-2023.
This report presents pooled COVID-19 vaccine effectiveness (VE) estimates for the first, second and third booster doses (compared to complete primary vaccination with no booster) against hospitalisation due to COVID-19 and COVID-19-related death in resident populations ≥50 years of age living in the community.
In this report, we present an update of the 2020 primary systematic review, to take into account more recent evidence on the efficacy, effectiveness and safety of newer and/or enhanced seasonal influenza vaccines for the prevention of laboratory-confirmed influenza in individuals aged 18 years and over.
Risks of an adverse event following influenza vaccination are far less common than complications related to influenza itself, and the adverse events are generally localised and mild.
Injected trivalent inactivated influenza vaccines are most commonly used throughout the world. Influenza antigen preparation varies between manufacturers.
