Overview

Extension of the post thaw expiry of Comirnaty (30microgram/dose) concentrate for Adults and Adolescents  is no longer supported by Pfizer.

Background

In January 2022, Pfizer permitted certain thawed batches of Comirnaty (30microgram/dose) concentrate for Adults and Adolescents to have their post-thaw expiry dates extended from 31 to 45 days. This permission is no longer applicable and so the SPS standard operating procedure supporting the process has been withdrawn.

All Comirnaty (30microgram/dose) concentrate for Adults and Adolescents is supplied from the NHS’s logistics partners is already labelled with a 31-day post-thaw expiry date. No extensions may be applied.
