It may take 2 to 7 days to stabilize the temperature in a newly installed or repaired refrigerator or 2 to 3 days for a freezer. Before using a unit for vaccine storage, check and record the minimum and maximum temperatures each workday for two to seven days. If temperatures cannot be recorded using a continuous digital data logger, check and record temperatures a minimum of two times each workday. Once you have two consecutive days of temperatures recorded within the recommended range, your unit is stable and ready for use. Recommended temperatures are between 2°C and 8°C (36°F and 46°F) for the refrigerator and between -50°C and -15°C (-58°F and +5°F) for the freezer.

Check and record storage unit minimum and maximum temperatures for the time since last measurement at the start of each workday. This is a requirement for VFC providers. The minimum and maximum temperatures recorded should be those obtained since the last workday when the minimum and maximum temperatures were reset. If your device does not display minimum and maximum temperatures, then check and record the current temperature a minimum of 2 times (at the start and the end of the workday). This should be done even if there is a temperature alarm at some point during the day.

Congratulations on your hard work! You would be surprised at the number of people who, just like you, do a careful job of recording temperatures, but then they fail to act on them when the temperatures go out of range. Always take immediate action when you notice an out-of-range temperature. You may need to move the vaccines temporarily to a more reliable storage unit and determine the source of the problem. It may be something quite fixable (e.g., excessive lint or dust on the coils), and you will be back in business after you determine that the temperature is back in range after a few hours.

Above all, don’t chart an out-of-range temperature and not act on it! Immunize.org has created temperature recording logs and a troubleshooting record to document unacceptable vaccine storage events. The CDC Storage and Handling Toolkit contains detailed guidance on the management of a temperature excursion. See pages 15–17 at www.cdc.gov/vaccines/hcp/downloads/storage-handling-toolkit.pdf. Refer to the addendum to the toolkit for specific guidance on mpox vaccines: www.cdc.gov/vaccines/hcp/downloads/storage-handling-toolkit-addendum.pdf.
