Symptom narrative

Bexsero administration instead of Menquadfi; This non-serious case was reported by a other health professional via call center representative and described the occurrence of wrong vaccine administered in a 11-year-old male patient who received Men B NVS (Bexsero) (batch number TP294, expiry date 31-OCT-2024) for prophylaxis. Co-suspect products included Meningococcal vaccine A/C/Y/W conj (tet tox) (Menquadfi) for prophylaxis. On 03-NOV-2023, the patient received Bexsero. On an unknown date, the patient did not receive Menquadfi. On 03-NOV-2023, an unknown time after receiving Bexsero, the patient experienced wrong vaccine administered (Verbatim: Bexsero administration instead of Menquadfi). The outcome of the wrong vaccine administered 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: 24-MAR-2025 The health care professional wanted to know how to proceed after realizing that a patient received more than one year ago Bexsero instead of Menquadfi, which led to wrong vaccine administered (according to the patient's administration schedule) when he was 11 years old. The vaccine administration facility was the same as primary reporter.
