When documenting vaccination, which details are essential to record?

• A. Lot number and patient age only.
• B. Expiry date only.
• C. Lot number, expiry date, administration site, and administration details.
• D. Manufacturer and price.

Answer: (C)

Recording vaccines requires information that ensures safety, traceability, and proper follow-up. The most complete and accurate documentation includes the lot number, expiry date, the administration site, and the administration details (date and time, route, and dose). The lot number lets you identify the exact vaccine batch in case of a recall or an adverse event. The expiry date confirms the vaccine was potent and safe to use at administration. The administration site helps verify the correct technique and is useful when planning future injections or evaluating local reactions. The administration details ensure the patient received the correct dose, via the intended route, on the scheduled date, which is essential for maintaining the vaccination schedule.

Recording only the expiry date misses batch traceability and dosing specifics. Recording only the lot number omits when and how the vaccine was given. Manufacturer and price are not essential for patient safety or surveillance and do not capture the administration details needed for accurate records.
