In the cold chain for vaccines in India, the temperature at which vaccines should be stored at the Primary Health Centre (PHC) level is:

• A -15°C to -25°C
• B 0°C to 4°C
• C 10°C to 15°C
• D 2°C to 8°C ✓

Explanation

At PHC level, vaccines are stored at 2°C to 8°C in Ice Lined Refrigerators (ILRs). The cold chain hierarchy in India is: State → District (ILR at 2-8°C and Deep Freezer at -15 to -25°C) → PHC (ILR at 2-8°C) → Sub-Centre (vaccine carrier with ice packs). OPV is the only vaccine stored at -15 to -25°C at district and state level, while other vaccines are at 2-8°C.
