Protocol for Evaluating Freezing in the Vaccine Cold Chain
This protocol is designed to document the level of freezing in the cold chain and identify specific problem areas where corrective actions are warranted. It can be tailored to an individual program’s resources: a simple, low-cost study can be done without sophisticated monitoring tools, or a more comprehensive approach can be taken to provide more details. This document is part of a series that describes the serious risk of freezing vaccines and contains World Health Organization-recommended freeze-prevention strategies targeted toward all levels of storage and transport of vaccines.
