NanoS100-SwIAV elicited antigen-specific localized SIgA responses in respiratory tract and lungs of vaccinated pigs. Five-week-old SPF pigs were administered twice ID/IM with NanoS100-SwIAV, Nano11-SwIAV or control NanoS100 and challenged at post-prime vaccination day 35 with SwIAV H1N1-OH7. Nasal swab samples collected at DPC6 were analyzed by ELISA for detecting specific SIgA antibody responses against: A, B H1N1-OH7; C, D H1N2-OH10; E, F H3N2-OH4; in BAL fluid against G, H H1N1-OH7; I, J H1N2-OH10; K, L H3N2-OH4; and in lung lysate against M, N H1N1-OH7; and O, P H3N2-OH4 SwIAV. Data represent the mean value of 7–8 pigs ± SEM. Statistical analysis was performed by two-way ANOVA followed by Bonferroni post-test. Letters a, b and c refer to significance between NanoS100 + Challenge vs Nano11-SwIAV + Challenge, NanoS100 + Challenge vs NanoS100-SwIAV + Challenge, and Nano11-SwIAV + Challenge vs NanoS100-SwIAV + Challenge, respectively, at the indicated dilution
