What temperature range should vaccines be stored at, and what equipment feature is required?

• A. Between -20°C and -10°C with a digital thermometer
• B. Between 2°C and 8°C, with an alarmed thermometer
• C. Between 8°C and 15°C with a standard thermometer
• D. Between 0°C and 4°C with a basic thermometer

Answer: (B)

Vaccines should be stored in a refrigerator at 2°C to 8°C to preserve their potency. This cold chain must be actively monitored, so an alarmed thermometer is required to alert staff immediately if the temperature drifts outside the safe range, allowing prompt corrective action before any vaccines are compromised. Other ranges involve freezing or higher temperatures that can damage vaccines, and a basic thermometer alone may not provide timely alerts.
