Temperature monitors for vaccines and the cold chain
This document describes the cold-chain monitor, the vaccine vial monitor (VVM), Freeze WatchTM, Stop!WatchTM and the diphtheria-tetanus vaccine (DT) & tetanus toxoid (TT) shipping indicator. To retain maximum potency a vaccine should be kept in its safe temperature range. The safe range varies between vaccines and between stages of the cold chain. The cold-chain monitor, Freeze WatchTM and the DT and TT shipping indicator are intended to help managers and health workers ensure that the cold chain functions
correctly from the point of manufacture to the point of use. Stop!WatchTM monitors temperatures inside refrigerators. The vaccine vial monitor monitors vaccine potency, registering the effect of heat on individual vials of vaccine.
