Antibody responses toward influenza virus antigens in the pre-challenge serum of vaccinated ferrets. Six weeks after the booster vaccination, pre-challenge serum was collected from TIV vaccinated, viral vector vaccinated, and naïve ferrets and IgG antibody responses toward influenza virus antigens were assessed via ELISA. Shown are antibody responses toward the H3 (A), H7 (B), H10 (C), cH4/3 (D), NP (E), and M1 (F) recombinant proteins. HI (G) and microneutralization titres (H) were also assessed. The data are presented as individual replicates and the mean for each group is presented as line. n = 4 ferrets/group. *p ≤ 0.05, **p ≤ 0.01, ***p < 0.005 when naïve controls were compared to individual vaccination groups as determined by one-way analysis of variance, followed by a Bonferroni multiple-comparison test.
