A major problem in immunization programs throughout the world has been the challenge of monitoring and managing the temperature of vaccines as they travel through the distribution chain to the destinations where they are used. This report provides a historical profile on the development and advancement of vaccine vial monitors, which is a heat exposure indicator that can be placed on individual vaccine vials. The oral polio vaccine was one of the first subprojects to test this technology, and it is now a standard feature on all vaccines purchased through United Nations agencies.
