In this study pulmonary vaccination with a new influenza subunit vaccine powder was evaluated. Vaccine powder was produced by spray-freeze drying (SFD) using the oligosaccharide inulin as stabilizer. Immune responses after pulmonary vaccination of BALB/c mice with vaccine powder were determined and compared to those induced by intramuscular and pulmonary vaccination with a conventional liquid subunit vaccine. All vaccinations were performed without adjuvant. Pulmonary vaccination with liquid subunit vaccine resulted in systemic Immoral (IgG) immune responses similar to intramuscular immunization. In contrast, the vaccine powder delivered by the pulmonary route, induced not only systemic Immoral (IgG) responses, but also cell-mediated (II-4, IFN-gamma) and mucosal immune responses (IgA, IgG). This study demonstrates that the combination of pulmonary antigen delivery and antigen powder production by SFD improves the immunogenic potential of (influenza subunit) antigen. In conclusion, vaccination with a non-adjuvanted SFD subunit vaccine powder by inhalation might be feasible and could be an alternative to conventional parenteral vaccine administration.
