Figure 3

Neuraminidase inhibition (NI) antibody titers against the vaccine strains post-vaccination (PV) 1, 2 and 3. Geometric mean NI antibody titers and the standard deviation were determined 4 weeks post each vaccination. Black dotted lines indicate the detection limit (10). The colors of the bars are based on the NA lineage of the vaccine strains. Blue, N1pandemic; orange, H1N2 A/swine/Scotland/410440/94-like N2; green, N1avian; dark red, H3N2 A/swine/Gent/1/84-like N2. TIV, Respiporc® FLU3; BIV, GRIPORK®; MOV, Respiporc® FLUpan H1N1. Representative virus strains that are genetically closely related to the vaccine strains were used in the NI assay (Figure 1).
