No adverse event; HCP called to report that an extra (second) dose of MMR II was inadvertently administered to a 15 month old patient on the same day (4/21/2025), at the same office visit within 2 minutes of the first dose. HCP stated it was not product confusion. T; This spontaneous report was received from a registered nurse and refers to a 15-month-old patient of unknown gender. The patient's medical history, concurrent conditions, and concomitant therapies were not reported. On 21-APR-2025, the patient was vaccinated with a dose of Measles, Mumps, and Rubella (Wistar RA 27-3) Virus Vaccine, Live (M-M-R II) (valid lot #Y014094, expiration date reported and confirmed as 19-AUG-2026) at a dose 0.5 mL as prophylaxis, reconstituted with a sterile diluent (indication, dose, expiration date, and lot # were not reported). On the same day, after 2 minutes, an extra dose of the suspect vaccine (as described above [however it was not clear of the same lot number of Y014094 corresponded to both doses]) was inadvertently administered to the patient (accidental overdose). It was confirmed that it was not product confusion. The nurse simply picked up the wrong syringe on the tray. There were several vaccinations that were being administered to a set of twins, and the wrong one was selected from the ones that were out and prepped. No adverse effects were reported (no adverse event).
