As of January 1, 2018, the CDC required all providers to use continuous temperature monitoring devices (data loggers) to monitor vaccines distributed by the VFC program. Routine review and accessibility of temperature data is critical for determining whether vaccine has been properly stored and for assessing usability of vaccine that was involved in a temperature excursion.


To meet program requirements the device must be equipped with:


  • A temperature probe
  • An active temperature display that can be easily read from the outside of the unit
  • The capacity for continuous monitoring and recording capabilities where the data can be routinely downloaded
