Vaccination Strategies for Ebola in the Democratic Republic of Congo: The WHO-Ebola Modeling Collaboration.

Objectives: Assess the effectiveness of ring vaccination in controlling an Ebola virus outbreak in the Democratic Republic of Congo.

Methods: This analysis focuses on two areas of the Democratic Republic of Congo, Beni and Butembo/Katwa, which were affected during the 2018-2020 Ebola outbreak. To simulate Ebola virus transmission, we used a spatially explicit agent-based model with households, health care facilities, and Ebola treatment units.

Ring vaccination with rVSV-ZEBOV under expanded access in response to an outbreak of Ebola virus disease in Guinea, 2016: an operational and vaccine safety report.

Background: In March, 2016, a flare-up of Ebola virus disease was reported in Guinea, and in response ring vaccination with the unlicensed rVSV-ZEBOV vaccine was introduced under expanded access, the first time that an Ebola vaccine has been used in an outbreak setting outside a clinical trial. Here we describe the safety of rVSV-ZEBOV candidate vaccine and operational feasibility of ring vaccination as a reactive strategy in a resource-limited rural setting.

Methods: Approval for expanded access and compassionate use was rapidly sought and obtained from relevant authorities.
