Pfizer-BioNTech Vaccine Gets Approval & Expiration Extension

Pfizer-BioNTech Vaccine Gets Approval & Expiration Extension

The Pfizer-BioNTech vaccine has been granted official Food and Drug Administration (FDA) approval! The vaccine will now be marketed as Comirnaty (koe-mir’-na-tee), for the prevention of COVID-19 disease in individuals 16 years of age and older. Although the full approval is only for individuals 16 years of age and older, Comirnaty can still be given to individuals 12 through 15 under the existing EUA. The Comirnaty vaccine is still contracted under the federal government and will not be distributed commercially at this time. Providers are expected to continue following the CDC Provider Agreement terms set forth at the time of enrollment with PDPH.

In addition to the FDA’s full approval, an amendment to the EUA for the Comirnaty vaccine has been made to extend the expiration dates from 6 to 9 months.

Cartons and vials of Pfizer-BioNTech’s Comirnaty vaccine may remain in use for 3 months beyond the printed date as long as authorized storage conditions (-90°C to -60°C or -130°F to -76°F) have been maintained. Frozen vials stored at -25°C to -15°C and refrigerated vials stored at 2°C to 8°C are NOT eligible for extension.
