The Viral Vaccine and Therapeutics program at IBT is focused on the viral hemorrhagic fever (VHF) viruses Ebola and Marburg. These viruses cause severe diseases in humans and apes leading to death rates up to 70-90%. There are currently no vaccines or therapeutics available for most VHFs.

IBT is developing two platforms for filovirus vaccines, one based on a proprietary virus like particle technology and a second generation platform based on rational immunogen design. IBT's work on filovirus vaccines is supported by the National Institute of Allergy and Infectious Diseases (NIAID). IBT is collaborating with the University of Texas Medical Branch for development of both platforms.
