neutropenia; thombocytopenia/low platelets; Patient's lab work had stopped 'growing and restarted 'growing'.; concomitantly administered STERILE DILUENT Reconstituted PROQUAD instead of the Intended MMRII; Accidental overdose; This spontaneous report was received from a physician referring to a 15-month-old patient of unknown gender. The patient's pertinent medical history, concomitant medications and drug reactions/allergies were not reported. On 28-SEP-2022, the patient was meant to be administered measles, mumps, and rubella (wistar ra 27-3) virus vaccine, live (M-M-R II) subcutaneous injection for prophylaxis (strength, dose, lot #, expiration date and route of administration were not provided) but the patient was inadvertently vaccinated with measles, mumps, rubella and varicella (oka-merck) virus vaccine live (PROQUAD) subcutaneous injection (therapy type: rHA, lot #W004029, expiration date was unknown, but upon internal validation established as: 02-AUG-2023) for prophylaxis (strength, dose and route of administration were not provided) with concomitantly administered sterile diluent (manufacturer unknown) solution for injection/infusion (strength, dose, frequency, indication, lot# and expiration date and route of administration were not provided) instead of the intended measles, mumps, and rubella (wistar ra 27-3) virus vaccine, live (M-M-R II) (wrong product administered). On the same date, the patient was vaccinated with varicella virus vaccine live (oka/merck) (VARIVAX) subcutaneous injection (lot #U039722, expiration date: 15-DEC-2023) for prophylaxis (dose, strength, and route of administration were not provided) with concomitantly administered sterile diluent (manufacturer unknown) solution for injection/infusion (strength, dose, frequency, indication, lot# and expiration date and route of administration were not provided) (accidental overdose). On unknown dates, the patient's lab work had stopped "growing" and restarted "growing" (laboratory test abnormal). On unknown dates, the patient experienced neutropenia and thombocytopenia/low platelets (thrombocytopenia). The outcome of all events was not reported. The action taken with all suspect therapies was not reported. The causal relationship between all events and measles, mumps, rubella and varicella (oka-merck) virus vaccine live (PROQUAD), varicella virus vaccine live (oka/merck) (VARIVAX) and sterile diluent (manufacturer unknown) was not reported. The causal relationship between events of laboratory test abnormal, neutropenia and thrombocytopenia and measles, mumps, and rubella (wistar ra 27-3) virus vaccine, live (M-M-R II) was not related. Upon internal review, the events neutropenia and thrombocytopenia were determined to be medically significant.
