Greetings, 

The Food & Drug Administration has approved an amendment to the EUA for Pfizer Tris COVID-19 vaccine extending the shelf-life of the following Pfizer product formulations from 9 to 12 months: 

• Pfizer Tris Pediatric vaccine (Orange Cap for ages 5 through 11, with diluent).
• Pfizer Adult Tris (Gray Cap for ages 12+, no diluent).

Vials stored consistently in an ultra-low temperature freezer at -90^oC to -60^oC (-130^oF to -76^oF) may remain in use for up to 12 months beyond the date of manufacture printed on the vials and cartons.  Vaccine stored in refrigerated vials (2^oC to 8^oC) are NOT eligible for extension, regardless of the expiration date. 

Vial expiration dates can also be checked using this resource from Pfizer-BioNTech.

Additional information on Pfizer storage and handling may be found at Administration Overview for Pfizer-BioNTech COVID-19 Vaccine | CDC.
