  • Description:
    Globally coordinated epidemiologic and virologic surveillance is the foundation of the influenza vaccine virus selection and development process and is a critical component of pandemic preparedness. The World Health Organization’s Global Influenza Surveillance and Response System (GISRS) was established in 1952 to monitor the frequent changes in influenza viruses with the aim of reducing influenza disease impact through the use of vaccines containing currently circulating strains. The GISRS network consists of national influenza centers (NICS) which conduct influenza virus surveillance and study influenza disease trends. There are also a number of designated WHO Collaborating Centers that conduct further research and analysis on information and samples gathered by the NICS. Currently there are 142 NICs in 112 countries around the world and 6 WHO collaborating centers. Twice a year, WHO convenes technical consultations (vaccine composition meetings) to make recommendations on the viruses to be included in influenza vaccines for the following influenza seasons in the Northern and Southern Hemispheres, respectively. The committee assembled by WHO comprises representatives from the 6 WHO Collaborating Centers and four Essential Regulatory Laboratories (ERLs, in Australia, Japan, UK and USA) with observers from other laboratories NICs and other expert groups. CDC’s Influenza Division has served as a WHO Collaborating Center (CC) for Surveillance, Epidemiology, and Control of Influenza in Atlanta, Georgia since 1956 and is the largest global resource and reference center supporting public health interventions to control and prevent pandemic and seasonal influenza.
