Vaccine Storage Monitoring
Vaccine storage monitoring ensures vaccines are stored within strict 2-8°C temperature ranges using continuous IoT monitoring with real-time alerts.
What is Vaccine Storage Monitoring?
Vaccine storage monitoring is the continuous tracking of temperature conditions in vaccine refrigerators, freezers, and cold rooms to ensure vaccines remain within their required storage temperature range — typically 2-8°C for most vaccines and -15°C to -25°C (or -60°C to -80°C for mRNA vaccines) for frozen products.
The WHO Pre-Qualification of Diagnostics Programme (PQS) and CDC Vaccines for Children (VFC) programme both mandate continuous digital temperature monitoring with data loggers that record at least every 30 minutes and provide excursion alerts.
Why It Matters
Vaccines are among the most temperature-sensitive pharmaceutical products. Exposure to temperatures outside the specified range — even briefly — can reduce potency or render vaccines completely ineffective. A single undetected excursion in a hospital vaccine refrigerator can waste thousands of doses and leave patients unprotected.
Frequently Asked Questions
What temperature should vaccines be stored at?
Most vaccines require storage at 2-8°C (refrigerator temperature). Some vaccines require frozen storage at -15°C to -25°C. mRNA vaccines (like some COVID-19 vaccines) require ultra-cold storage at -60°C to -80°C. Always follow the manufacturer's storage requirements.
What monitoring does the CDC VFC programme require?
The CDC Vaccines for Children programme requires a digital data logger that records temperatures at least every 30 minutes, has a current and valid Certificate of Calibration Testing, has an out-of-range alarm, and has a low-battery indicator.
