Figure 5.
HAI antibody immune responses in immunized ferrets measured against a panel of viruses. (A) H5 NP/MDV LAIV. (B) H8 NP/MDV LAIV. (C) H9 NP/MDV LAIV. (D) A/herring gull/Sarma/51/2006 (H6N1) wild-type virus. (E) cH11/1N1 LAIV virus bearing chimeric HA gene (the HA stalk domain of Cal09 and the HA head domain of A/northern shoveler/Netherlands/18/99 (H11N9)) and the NA gene of Cal09. (F) A/South Africa/3626/2013 (pH1N1) wild-type virus. The HAI titers for H5 and H8 antigens were determined using horse red blood cells; the remaining antigens were tested with chicken RBCs. * indicates significant difference with the mock-vaccinated group. The dashed line indicates the limit of detection.
