Injected trivalent inactivated influenza vaccines are most commonly used throughout the world. Influenza antigen preparation varies between manufacturers.
In this episode we take a closer look at the data collection for respiratory viruses and why we should take this more seriously than just a cough or a sneeze.
Genetic and antigenic characterization data generated at the Worldwide Influenza Centre for viruses with collection dates after 31 January 2023 until 31 August 2023 informed the WHO influenza vaccine composition meeting (VCM) in September 2023 when recommendations were made for the southern hemisphere (SH) 2024 influenza season.
This issue of the ECDC Communicable Disease Threats Report (CDTR) the period 28 January - 3 February 2024 and includes updates on SARS-CoV-2 variant classification, swine influenza, human cases of co-infection with seasonal influenza and avian influenza, influenza, western equine encephalitis, and an overview of respiratory virus epidemiology in the EU/EEA.
This report contains genetic and antigenic characterization data generated at the Worldwide Influenza Centre for viruses with collection dates after 31 January 2023 until 31 August 2023.
Several viral and bacterial respiratory pathogens are expected to continue co-circulating at variable levels during the coming months, and contribute to increased morbidity and mortality during this period. This is typical of every winter season.
This Reporting Protocol describes data collection for influenza, COVID-19, and other respiratory viruses (such as RSV or new viruses of public health concern) in the EU/EEA and wider WHO European Region. Data collection is integrated for most datasets in line with the operational considerations for respiratory virus surveillance in Europe.
