How should vaccines be stored to maintain potency and safety?

• A. Keep vaccines in the freezer.
• B. Store vaccines at room temperature.
• C. Store in a refrigerator and avoid warming to room temperature.
• D. Expose vaccines to direct sunlight.

Answer: (C)

Vaccines stay potent only when kept in a controlled cold environment—the cold chain. Store them in a refrigerator at about 2 to 8 degrees Celsius and protect them from light. Warming to room temperature or exposing vaccines to direct sunlight can break down the active components, reducing effectiveness and potentially compromising safety. Freezing is not appropriate for most vaccines unless the manufacturer specifies it. By following storage guidelines, using a calibrated thermometer, and avoiding temperature fluctuations, you keep vaccines effective and safe until administration.
