A new study in Vaccine examines Sudan’s oral cholera vaccine (OCV) campaigns deployed in response to the 2023–2024 outbreaks. Focusing on emergency mass vaccinations, the research documents deployment logistics and financial efficiency amid two consecutive cholera waves. The paper highlights key implementation challenges encountered in the field, such as maintaining cold chain integrity, mobilizing rapid response teams, and reaching affected communities efficiently. Vaccine wastage was found to be minimal (<0.0001 %), and the average operational cost per dose was $0.65.
This analysis is significant for public health planners and funders in cholera-endemic regions. By illuminating both operational successes and bottlenecks, the study offers actionable insights for improving future OCV efforts in Sudan and comparable settings. These include refining budget allocations, strengthening logistics, and adapting campaign strategies to local contexts—ultimately contributing to more effective and cost-efficient cholera control.
