How to select the right solution to address freezing during transport

Vaccine transport systems using fully-frozen ice packs without freeze-preventative devices are demonstrated to expose ~20% of vaccines to freezing. This document is intended to help EPI decision makers to decide on a suitable solution to mitigate freezing risks during transport of vaccines. Specifically the document provides information on the advantages and potential risks of two solutions to mitigate freezing during transport: 1)  Incorporating fully frozen ice packs within Freeze-preventative carriers and cold boxes and 2) Using conventional carriers and cold boxes with cool water packs. Following the decision, decision makers can refer to the resource on Implementation planning that helps provide a framework on how the above solutions can be implemented.
