Why is documenting temperatures during vaccine storage important?

• A. For decoration.
• B. For shipping records only.
• C. Not necessary.
• D. For audit and traceability.

Answer: (D)

Documenting temperatures during vaccine storage ensures the cold chain stays intact and creates a verifiable record for safety, quality, and regulatory compliance. Vaccines are sensitive to temperature; keeping and recording that they stayed within the required range demonstrates potency was preserved and allows audits to confirm proper handling. If a temperature excursion occurs, the log shows exactly when and where it happened, which lots were affected, and what corrective actions were needed, enabling effective traceability and accountability across the supply chain.

Other options don’t fit because decoration has nothing to do with vaccine safety or potency, shipping records alone don’t capture ongoing storage conditions, and claiming it isn’t necessary ignores regulatory and QA requirements for maintaining vaccine integrity.
