These countries had previously faced yellow fever outbreaks despite extensive vaccination campaigns. Each pilot study included an analysis to determine the cause of the yellow fever outbreak and featured two dynamic workshops with national stakeholders. The first workshop was held on-site to review and discuss preliminary findings, and the second was an online session focused on identifying necessary corrective actions and setting priorities. The pilot programs enabled the three countries to:

This toolkit should be available soon for wide use.
