Expiration Dates

Determining when a vaccine or diluent expires is an essential step in the vaccine preparation process. 

Always verify the vaccine and diluent’s expiration dates before beginning the preparation process.

NEVER administer expired vaccine or diluent. 

As the expiration date approaches, contact the manufacturer to determine if it has been extended. Do not discard vaccine without ensuring the expiration date has passed.
