Infectious Diseases 2023

The goal of OFFLU Avian Influenza Matching (AIM) project (OFFLU-AIM) is to provide improved information on antigenic characteristics of avian influenza viruses to support vaccination programs against avian influenza. OFFLU-AIM serves as a platform where current epidemiological, genetic, and antigenic information on AI viruses circulating in different geographic regions is analysed and made freely accessible. This information is of value for countries considering introduction of vaccination as an additional preventive/control measure. The OFFLU report focuses on HPAI viruses of the H5Nx subtype in the goose/Guangdong/1/96 lineage (gsGD).
