When reconstituting a multi-dose vaccine, what should be done with the vial?

• A. Label the vial with the date and time mixed
• B. Immediately dispose of it after use
• C. Store at room temperature
• D. Shake vigorously to mix thoroughly

Answer: (A)

Labeling the vial with the date and time of reconstitution is essential because once a vaccine is reconstituted, it often has a limited usable period. The label provides a clear record of when the product was prepared, so you can determine if it’s still within the time window allowed for administration and keep accurate treatment records. This helps prevent giving a vaccine that may have degraded or become unsafe to use. Disposing of the vial immediately isn’t correct because reconstituted vaccines may still be usable within their designated time frame if stored and handled according to the manufacturer’s guidelines. Storing at room temperature is typically not appropriate unless the product label explicitly allows it; many vaccines require refrigeration or other specific conditions to maintain potency. Shaking vigorously is not advised because it can cause foaming or shear stress that may affect the vaccine’s integrity—gentle mixing or rolling, as directed by the product instructions, is preferred.
