    AbstractExperimental Ebola virus (EBOV) vaccines have previously been shown to protect animals against a high dose intramuscular (IM) challenge, which is seen as a stringent challenge model. However, the protective efficacy against other modes of infection, such as contact with infectious hosts, is unknown. Using a previously established EBOV transmission animal model, we evaluated the efficacy of an adenovirus-based EBOV vaccine given to guinea pigs (gps) 4weeks before direct contact with untreated, infectious animals. Prior vaccination resulted in robust levels of EBOV-specific antibodies and conferred complete protection in gps. These results support the use of vaccines to prevent EBOV transmission between hosts.Crown Copyright © 2015. Published by Elsevier B.V. All rights reserved.
