Homologous titres (i.e., where the HI test antigen titer matches the probable vaccine seed strain) are indicated by bold, highlighted text, except for the Chinese origin vaccines that were subsequently determined to contain a seed strain using A/goose/Guangdong/1/1996 (rgGD/96), as this conclusion was reached subsequent to the serological testing.
