What should you do with leftover vaccine after storage has begun to degrade (as little as 2 hours)?

• A. Keep leftovers for next month.
• B. Store leftovers for the next vaccination event.
• C. Use leftovers within a day.
• D. Throw away leftover vaccine; it loses effectiveness during storage.

Answer: (D)

The main idea here is vaccine potency and safe disposal when the cold chain is compromised. Vaccines must be kept at precise temperatures to stay effective. If storage has begun to degrade, even after a short time, the vaccine’s potency can drop and you can’t guarantee it will immunize. Because you can’t know the actual strength of the dose once degradation starts, the safest and most responsible action is to discard any leftovers. Reusing leftovers later, or trying to use them within a day or at a future event, risks giving a nonprotective dose. Throwing away leftover vaccine protects patients and maintains the integrity of the vaccination effort.
