Influenza viruses are among the most significant human pathogens, responsible for increased seasonal morbidity and mortality particularly in immunodepressed and chronically ill. Conventional vaccination with non-replicative vaccine is currently performed by injection. In the present study, we explore simple spray-dried lipid formulations containing whole inactivated virus or split-subunit vaccine that allow aerosolization and thus, mucosal vaccination of the pulmonary tract. We show that by using biocompatible excipients already approved for human use, one could engineer microparticles that induce substantial local and systemic immunity subsequent to pulmonary administration. Exposure of the bronchial-associated lymphoid tissue (BALT) to vaccine was more effective than parenteral or nasal administration in triggering specific immunity. Co-formulation of a biocompatible surfactant detergent greatly ameliorated the immune profile of microparticles containing a whole inactivated virus vaccine. In addition, mere formulation of a licensed split-subunit vaccine significantly enhanced its immunogenicity. Together, our data underline a simple strategy to convert conventional parenteral vaccination of currently available non-replicative vaccines against influenza virus, into one that is more effective and practical upon respiratory administration.
