Filovirus subunit protein immunogens are produced using a recombinant expression system and combined with one or more adjuvants in immunogenic formulations. The subunit proteins include GP95, GP-FL, VP40, VP24, and NP derived from Ebola Virus and Marburg Virus. Adjuvants include saponins, emulsions, alum, and dipeptidyl peptidase inhibitors. The disclosed immunogenic formulations are effective in inducing strong antibody responses directed against individual Filovirus proteins and intact Filovirus particles as well as stimulating cell-mediated immune responses to the Filoviruses.
