Cholera dynamics and impact of preventive vaccine in endemic zones of DRC, 2021-2026

In the context of cholera resurgence, the Oral Cholera Vaccine (OCV) constitutes an important control strategy. Preventive OCV campaigns are now deployed, especially in endemic areas such as in the Democratic Republic of the Congo (DRC). Impact of these campaigns should be assessed to better design future vaccination strategies. Since 2021, a multi-study project was put in place in two sites in the DRC: Goma (urban) and Bukama (rural). This project evaluates the impact of preventive OCV campaigns in cholera endemic areas of the DRC and offers elements to guide vaccination strategies specific to urban or rural contexts.
