This report provides a record of the impact noted by countries on HIV services and monitoring capacity which can be used retrospectively to better understand the effects of the COVID-19 pandemic on the HIV situation in the European Region.
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.
