Vaccine Volumes and Cold Chain Capacity Requirements" />Vaccine Volumes and Cold Chain Capacity Requirements" />
This module of the WHO Vaccine Management Handbook describes how to calculate vaccine volumes and evaluate the cold chain capacity requirements of a vaccine supply chain. This module also provides guidance on how to calculate cold chain storage needs for coolant-packs and the dry-storage capacity needed for immunization-related commodities. The most basic question for those who are managing vaccine distribution is whether there is sufficient cold chain capacity to store and deliver all the required vaccine products at the recommended temperatures at all points of the vaccine supply chain. To ensure that sufficient cold chain capacity is available where and when it is needed, it is important to:
