Comparative cost models of a liquid nitrogen vapor phase (LNVP) cold chain-distributed cryopreserved malaria vaccine vs. a conventional vaccine

► A liquid nitrogen vapor phase (LNVP) cold chain model is described. ► LNVP distribution costs for a cryopreserved malaria vaccine are presented. ► Costs are compared to conventional 2-8 °C cold chain vaccine distribution. ► Capital and recurrent costs, and costs for each level and each component are given. ► Overall 5-year costs for the LNVP and 2-8 °C cold chain models were very similar.
