Expired Dose Administered; This non-serious case was reported by a pharmacist via call center representative and described the occurrence of expired vaccine used in a patient who received HAB (Twinrix) (batch number 4KF75, expiry date 03-JAN-2025) for prophylaxis. On an unknown date, the patient received Twinrix. On an unknown date, an unknown time after receiving Twinrix, the patient experienced expired vaccine used (Verbatim: Expired Dose Administered). The outcome of the expired vaccine used was not applicable. This report is made by GSK without prejudice and does not imply any admission or liability for the incident or its consequences. Additional Information: GSK Receipt Date: 05-JUN-2025 The pharmacist reported that a patient was mistakenly administered an expired Twinrix vaccine, which led to expired vaccine used. So wanted to know the lot number of that and see if there is any recommendations.
