PREDAC-H3: Bioinformatics platform for antigenic surveillance of human influenza H3N2 virus
Human influenza H3N2 virus caused largest mortality and morbidity among seasonal influenza virus. Timely surveillance is critical for accurate selection of vaccine strains. Here, we provide a computational platform for antigenic surveillance of the virus based on the HA1 protein sequence. It includes the following four functions.
Antigenic variant determination: determine the antigenic variant based on HA1 protein sequence
Antigenic cluster inference: infer the antigenic cluster based on HA1 protein sequence
Antigenic world map: display the antigenic cluster distribution in the world map
Antigenic cluster dynamics: display the antigenic cluster dynamics in a country/region
