Fl-V is a recombinant plague antigen comprising the capsular (Fl) and virulence-associated (V) proteins. Given intramuscularly with Alhydrogel, it protects mice against challenge, but is less effective in non-human primates against high-dose aerosolized Yersinia pestis challenge, perhaps because it fails to induce respiratory immunity. Intranasal immunization of mice with Fl-V formulated with a Proteosome-based adjuvant (Protollin™), elicited high titers of specific IgA in lungs whereas intranasal Fl-V alone or intramuscular Alhydrogel-adsorbed Fl-V did not. The Protollin-adjuvanted Fl-V vaccine also induced high serum titers of specific IgG, comparable to those induced by intramuscular Alhydrogel-adsorbed Fl-V. Mice immunized intranasally with Protollin-Fl-V were 100% protected against aerosol challenge with 170 LD50 of Y. pestis and 80% against 255 LD50.
