The patient has had no side effects at this time.; PEDVAX HIB was accidently used as the diluent for MMR-II and VARIVAX instead of the Merck sterile diluent; Because of the PEDVAX HIB being used as the diluent for both MMR-II and VARIVAX, the patient received 1mL of PEDVAX HIB instead of the recommended dose of 0.5mL therefore receiving double the recommended dose of PEDVAX HIB.; Also, the PEDVAX HIB was given subcutaneously instead of intramuscularly since it was mixed as diluent with MMR-II and VARIVAX.; This spontaneous report was received from physician and refers to a 12-month-old female patient. The patient's concomitant therapy included pneumococcal vaccine conj 13v (crm197) (PREVENAR 13). The patient's concurrent conditions, medical history, allergies and drug reactions were not provided. On 30-JUN-2022, the patient was vaccinated with measles, mumps, and rubella (wistar ra 27-3) virus vaccine, live (M-M-R II) , 0.5 ml, administered subcutaneously, lot #U011995, expiration date: 15-APR-2023 (strength and dose number was not provided), and varicella virus vaccine live (oka/merck) (VARIVAX), 0.5 ml, administered subcutaneously, lot #U039726, expiration date: 15-DEC-2023 (strength and dose number were not provided) for prophylaxis. Haemophilus b conjugate vaccine (meningococcal protein conjugate) (LIQUID PEDVAXHIB) lot #U039951, expiration date: 22-JUN-2024 was accidentally used as the diluent for both measles, mumps, and rubella (wistar ra 27-3) virus vaccine, live (M-M-R II) and varicella virus vaccine live (oka/merck) (VARIVAX) instead of Merck sterile diluen (product preparation error). Because haemophilus b conjugate vaccine (meningococcal protein conjugate) (LIQUID PEDVAXHIB) being used as the diluent for both measles, mumps, and rubella (wistar ra 27-3) virus vaccine, live (M-M-R II) and varicella virus vaccine live (oka/merck) (VARIVAX), the patient received 1 ml of haemophilus b conjugate vaccine (meningococcal protein conjugate) (LIQUID PEDVAXHIB) instead of recommended dose of 0.5 ml, therefore receiving double the recommended dose of haemophilus b conjugate vaccine (meningococcal protein conjugate) (LIQUID PEDVAXHIB) (accidental overdose). Also, the haemophilus b conjugate vaccine (meningococcal protein conjugate) (LIQUID PEDVAXHIB) was given subcutaneously instead of intramuscularly since it was mixed as diluent with measles, mumps, and rubella (wistar ra 27-3) virus vaccine, live (M-M-R II) and varicella virus vaccine live (oka/merck) (VARIVAX) (incorrect route of product administration). The patient has had no side effects at this time (no adverse event).
