potential wrong vaccine; This non-serious case was reported by a nurse via call center representative and described the occurrence of wrong vaccine administered in a 17-year-old patient who received Men B NVS (Bexsero) (batch number PX7E2) for prophylaxis. Co-suspect products included Men ACWY-CRM NVS (Meningococcal polysaccharide groups A, C, W-135, Y conjugate vaccine) for prophylaxis. On 31-DEC-2024, the patient received Bexsero. On an unknown date, the patient did not receive Meningococcal polysaccharide groups A, C, W-135, Y conjugate vaccine. On 31-DEC-2024, an unknown time after receiving Bexsero and not applicable after receiving Meningococcal polysaccharide groups A, C, W-135, Y conjugate vaccine, the patient experienced wrong vaccine administered (Verbatim: potential wrong vaccine). 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: 11-APR-2025 Nurse mentioned that a 17 year old patient required by the school to get a meningococcal vaccine for types A, C, W, and Y. In their chart it states that they already received a Meningococcal b vaccine on December 31st 2024 that is Bexsero. The caller was unclear as to whether Bexsero was mistakenly administered instead of the required meningococcal vaccine for types A, C, W, and Y (potential wrong vaccine), or whether Bexsero was a different vaccine administered regardless of school requirements. Patient received Bexsero instead of meningococcal vaccine for types A, C, W, and Y, which led to wrong vaccine administered.
