Expiration and Beyond Use Date (BUD)

Determining when a vaccine or diluent expires is a critical step in proper storage and handling

All vaccines have expiration dates, and some routinely recommended vaccines have a beyond use date (BUD), which is calculated based on the date the vial is first punctured and the storage information in the package insert
