HI assay

Reams of Quantitative data: HI titres are collected into HI tables, showing assay values of strains (rows) against antisera (columns). Pictured above are example HI tables prepared by Jan de Jong of the Erasmus Medical Centre and the Dutch National Influenza Centre.

Antigenic map

The first antigenic map of the influenza A(H3N2) virus from 1968 to 2003. Each strain is coloured to represent the antigenic cluster to which that strain belongs, while the antisera used in the HI assays are shown as uncoloured open shapes. Clusters are named with two letters referring to the location of the first isolation and two digits refer to year of isolation. Both the vertical and horizontal axes represent antigenic distance; this is similar to the way both axes on a geographical map represent geographic distance.
