- A 7 days
- B 14 days
- C 28 days ✓
- D 42 days
Correct answer: C. 28 days
Explanation
Under the Open Vial Policy, eligible opened multi-dose vials can be reused at subsequent sessions for up to 28 days after opening, provided cold chain is maintained, the VVM is usable, and aseptic technique is followed. This reduces vaccine wastage under UIP.
