Abstract

An effort to develop a safe and effective vaccine for Marburg virus (MBGV), one of the filoviruses known to cause high mortality rates in humans, led us to compare directly some of the merits of modern versus classical vaccine approaches for this agent. Prior work had established the MBGV-glycoprotein (GP), the only known virion surface antigen, as a candidate for inclusion in a vaccine. In this study, we vaccinated groups of Hartley guinea pigs with killed MBGV, live attenuated MBGV, soluble MBGV-GP expressed by baculovirus recombinants, MBGV-GP delivered as a DNA vaccine, or MBGV-GP delivered via an alphavirus RNA replicon. Serological responses were evaluated, and animals were challenged with a lethal dose of MBGV given either subcutaneously or via aerosol. Killed MBGV and replicon-delivered MBGV-GP were notably immunogenic and protective against MBGV, but results did not exclude any approach and suggested a role for DNA vaccines in immunological priming.
