Desired virtuous cycle of supply-demand for cholera vaccines. A virtuous cycle of supply-demand for cholera vaccines can be reached by an increased demand (achieved through for example disease burden estimates and advocacy) which in turns leads to current producers increasing their production capacity or new producers entering the market. This results in a growing global production capacity which in turn can lead to lower prices and distribution of vaccine to more people. Figure inspired by Milstein et al. [58].
