Symptom narrative

Possible administration of only diluent; Possible administration of only diluent; patient being a 24-year-old male; This non-serious case was reported by a pharmacist via call center representative and described the occurrence of inappropriate dose of vaccine administered in a 24-year-old male patient who received MMR (Priorix) for prophylaxis. On 24-JUL-2025, the patient received the 1st dose of Priorix. On 24-JUL-2025, an unknown time after receiving Priorix, the patient experienced inappropriate dose of vaccine administered (Verbatim: Possible administration of only diluent), inappropriate preparation of medication (Verbatim: Possible administration of only diluent) and inappropriate age at vaccine administration (Verbatim: patient being a 24-year-old male). The outcome of the inappropriate dose of vaccine administered, inappropriate preparation of medication and inappropriate age at vaccine administration were 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-JUL-2025 A pharmacist called in to request data about the possible administration of Priorix after 2 patients where involved, where only one of them received only the diluent portion of the vaccine which led to inappropriate dose of vaccine administration and inappropriate preparation of medication, but they were unsure of whom. Only patient data was collected, with the first patient being a 24-year-old male which led to inappropriate age at vaccine administration.
