Vaccine & Medication Storage

CDC VFC-compliant temperature monitoring for vaccines, biologics, and temperature-sensitive medications. NIST-certified sensors with audit-ready PDF exports — for pharmacies, clinics, long-term-care facilities, and CDC VFC providers.

Why continuous monitoring beats spot-checks

CDC VFC rules require documented temperature readings at least twice daily, but most excursions happen between checks — overnight power dips, door left open after the last pull, a compressor that trips at 3am. A non-monitored fridge can drift out of the 36–46°F (2–8°C) safe range for hours before the morning check catches it. By then, the lot is compromised and the shot is unusable.

Required temperature ranges

What CDC VFC auditors accept

CDC's Vaccines for Children program requires a "digital data logger" with NIST-traceable calibration, continuous reading interval (typically 30 min or better), and exportable historical records. NIST certificates must be on file and re-verified annually. iMatrix NEO-1D NIST and NEO-1P NIST variants meet all of these requirements out of the box.

The emergency response

When a freezer trips an alert, you need to know within minutes, not at the next scheduled check. iMatrix Cloud pushes alerts via multiple channels and logs every notification attempt for audit. Even if the on-call pharmacist misses the first alert, the system keeps escalating until someone acknowledges.
