A vaccine has been kept within the recommended temperature range, but its expiry date has passed. What should the nurse do?
Correct answer: C. Do not use it and remove it according to local procedure
- A. Use it if the vial monitor looks acceptable
- B. Use it only for children older than one year
- C. Do not use it and remove it according to local procedure
- D. Mix it with a fresh vial to restore its potency
Explanation
A vaccine must not be used after its expiry date, even when its cold-chain temperature and vial monitor appear satisfactory. Expiry status is a separate safety requirement and the vial should be handled according to immunisation waste procedures.

Immunisation covers active and passive immunity, vaccine types, routine childhood schedules under Pakistan’s Expanded Programme on Immunization, administration routes and age-based timing. It also includes cold-chain maintenance, contraindications, adverse events following immunisation, missed doses and the distinction between vaccine protection and treatment of an established infection.
