In the cold chain for vaccine storage, the temperature at which vaccines should be stored at the Primary Health Centre level (PHC) is:
- A −15°C to −25°C
- B 0°C to +4°C
- C +2°C to +8°C ✓
- D +8°C to +15°C
Correct answer: C. +2°C to +8°C
Explanation
At PHC level and district cold chain points, vaccines are stored between +2°C and +8°C in Ice-Lined Refrigerators (ILRs). Only OPV requires storage at −15°C to −25°C (in deep freezers) at state and regional level stores. At sub-centre/village level, vaccines are transported in vaccine carriers maintained at +2°C to +8°C.
