H3 virus-specific hemagglutination inhibition (HAI) responses in ferrets with different exposure histories. Sera from ferrets infected with A/Hong Kong/4801/2014 (HK/4801) only (HK; A), or A/Switzerland/9715293/2013 (SWZ/13) followed by HK/4801 (SWZ/HK; B), or A/Texas/50/2012 (TX/50) followed by SWZ/13 and then HK/4801 (TX/SWZ/HK; C), or A/Uruguay/716/2007X175C (175C) followed by TX/50, SWZ/13, and then HK/4801 (175C/TX/SWZ/HK; D) were assessed for virus-specific HAI titers. Individual ferret titers with geometric mean titers (GMTs) (bar graphs) are shown.
