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.

COVID-19 vaccine expiration dates:

• The expiration date may change for some vaccines as more stability data become available.
