Why should vaccine management track lot numbers and expiration dates?

• A. To determine which patients receive vaccines based on age only.
• B. To prevent stockouts and ensure cold chain by tracking lot numbers and expiration dates.
• C. To track physician performance.
• D. To set vaccine prices.

Answer: (B)

Vaccine management hinges on controlling vaccine safety and supply by knowing exactly which doses are in use and for how long they remain usable. Tracking lot numbers and expiration dates lets you rotate stock so vaccines are used before they expire, reducing waste and the risk of stockouts due to expired doses. It also makes recall and safety investigations efficient, because you can quickly identify and pull a specific batch if a problem is found. Additionally, lot numbers tie each dose to its storage history and handling notes, helping ensure the chosen vaccines have stayed within the required cold chain for that batch. That combination—safe, effective vaccines available when needed—is why this practice is essential. The other options don’t address inventory control, vaccine safety, or storage integrity.
