View
All vaccines and diluents have expiration dates. The expiration date is the date by which the vaccine or diluents should be used. Vaccine and diluents should not be used after this date has passed. When the expiration date is marked with only a month and year, the vaccine or diluents may be used up to and including the last day of the month indicated on the vial. Any unused vaccine or diluents should not be used after this month has passed.

Multidose premixed vaccine vials contain bacteriostatic agents that prevent the growth of bacteria. These vaccines can be used until the date of expiration printed on the vial unless they become contaminated.
Single-dose vials are meant for one-time use only. Once the protective caps on single-dose vials have been unsealed, it may not be possible to determine if the rubber seals have been punctured. Therefore, do not open single-dose vials until you are ready to use them.
Expired vaccines and diluents should never be administered. Promptly remove expired vaccines from the refrigerator or freezer to avoid accidental use.
