Vaccine Cold Chain Verification

Inspection template for verifying vaccine refrigerator and freezer temperatures, storage practices, monitoring devices, and corrective actions in line with CDC VFC cold chain requirements.

Inspection Setup

• Inspection date and time recorded
• Storage unit identified
  Enter the refrigerator/freezer asset ID, room location, and unit type inspected.
• Inspector name and role recorded
• Inspection scope confirmed
  Confirm whether both refrigerator and freezer compartments were included, if applicable.

Temperature Verification

• Refrigerator temperature within acceptable range
  Record the current refrigerator temperature. Acceptable range is 36°F to 46°F (2°C to 8°C) unless site SOP specifies a tighter range.
• Freezer temperature within acceptable range
  Record the current freezer temperature. Use the manufacturer and CDC VFC storage requirements for the specific vaccine inventory in the unit.
• Continuous temperature monitoring device functioning
  Confirm the digital data logger or equivalent device is powered, displaying current readings, and recording min/max temperatures.
• Temperature alarm or excursion reviewed
  Confirm any alarm, out-of-range reading, or excursion since the last check has been reviewed and documented.

Storage Practices

• Vaccines stored in original packaging
  Confirm vaccines remain in original cartons or packaging where required to protect from light and support organization.
• Vaccines stored with adequate airflow
  Verify vaccines are not packed tightly and are not blocking vents, fans, or internal circulation pathways.
• Food, beverages, and non-vaccine items absent
  Confirm no food, beverages, or unrelated items are stored with vaccines in the unit.
• Vaccines separated by storage requirements
  Confirm refrigerated and frozen products are stored in the correct compartment and segregated by temperature requirement and lot control practices.
• Unit doors and seals in good condition
  Inspect doors, gaskets, and seals for visible damage, gaps, or condensation that could affect temperature stability.

Monitoring Devices and Documentation

• Temperature probe placed correctly
  Confirm the probe is located in the proper buffered or product-simulating medium and positioned according to site SOP/manufacturer guidance.
• Temperature logs complete and current
  Verify required temperature logs are complete, current, and signed/initialed per site procedure.
• Device calibration or verification status current
  Confirm the monitoring device calibration, validation, or verification is current per manufacturer and site policy.
• Backup monitoring method available
  Confirm a backup thermometer, data logger, or alternate monitoring method is available in case the primary device fails.

Corrective Actions and Release Decision

• Any deficiency or non-conformance documented
  Record whether any temperature excursion, storage issue, or monitoring failure was identified during the inspection.
• Corrective action documented for each issue
  Confirm each deficiency includes immediate containment actions, notification, and follow-up steps per CDC VFC/site SOP.
• Affected vaccine inventory placed on hold or quarantined
  Confirm any potentially compromised vaccine has been clearly identified, segregated, and not released for use until disposition is determined.
