In the Indian cold chain system, the Vaccine Van (State to District) is required to maintain which temperature range during transport?
- A -15°C to -25°C
- B +2°C to +8°C ✓
- C 0°C to +4°C
- D -25°C to -15°C with dry ice
Correct answer: B. +2°C to +8°C
Explanation
Vaccine vans used for transport from state to district and from district to PHC are required to maintain +2°C to +8°C. Only oral polio vaccine (OPV) requires deep-freeze storage (−15°C to −25°C) at central and state vaccine stores, but during PHC-level transport and storage, OPV is maintained at +2°C to +8°C in an ice pack. Most other UIP vaccines are stored at +2°C to +8°C throughout the cold chain. The cold chain equipment at PHC level (ILR) also maintains +2°C to +8°C.
