What are the typical temperature requirements for general medicines and vaccines in a Medical Store?

• A. General medicines: 15-25°C; vaccines: 2-8°C.
• B. General medicines: 2-8°C; vaccines: 15-25°C.
• C. -20 to 0°C; vaccines: 0-5°C.
• D. General medicines: 25-35°C; vaccines: -10 to 0°C.

Answer: (C)

Maintaining the right storage temperature is essential to keep medicines and vaccines effective and safe. In many medical stores, there are two practical cold-chain zones: a freezer for items that need freezing and a refrigerator for items that must be cooled but should not be frozen. The idea behind this arrangement is to protect different products according to how their active ingredients respond to temperature changes.

If vaccines are kept in a cooler range like 0-5°C, they sit in a controlled refrigeration zone that helps preserve their potency without risking damage from freezing. Keeping general medicines in the freezer range (-20 to 0°C) covers those products that require freezing to maintain stability or extend shelf life. While many medicines are stable at room temperature, and many vaccines are stored around 2-8°C, this two-zone approach reflects the principle of separating items by their stability needs and using appropriate equipment to maintain them.

In practice, always follow the product-specific storage instructions on the label, since exact ranges can vary by item.
