Additional information: Caller was a registered nurse calling about Pfizer COVID 19 gray cap vaccine bivalent. Patient had no other medications in 2 weeks. Patient was unintentionally given full vial (1.8mL) of bivalent vaccine grey cap instead of the intended 0.3mL dose. A patient received a whole vial of Bivalent multi-dose vial, after further information, that the patient received 5 doses and not the 6 doses. The nurse in the office provided vaccines to a patient 4-5 times over the dose. It was one of her Medical Assistants today that did not follow procedure. The Medical assistant had not given a dose before. She had been trained though. Instead of pulling 0.3mL up she pulled up the vial and gave the vial to the patient . It was reported that, contributing factors to the medication error were human error, not following protocol, and a lack of a double check step. Patient also received Influenza, Tdap and MCV4 vaccines on the same day; the nurse does not usually recommend patient get both Pfizer COVID and the flu vaccine the same day, but the patient wanted it. Patient reported fever, extreme pain in R arm (where Covid dose was given), severe headache, fatigue and intermittent coughing x 2 days post vaccination. On Friday 16Sep2022, the day of the overdose event, she spoke with the patient who reported no adverse events yet. However, on Saturday when the nurse checked in again, the patient reported having an immense fever, dizziness (but had not been eating since she did not want to leave her dorm room for not feeling good, so dizziness may be from lack of food), headache, right arm pain, and intermittent cough. The nurse has not spoken to her since but did hear an update, and it is her understanding that the patient was doing better today (on 16Sep2022). Most of the adverse events reported have resolved and the only remaining complaint was the sore arm. Therpeutic meaures included, Tylenol, ice pack for comfort. It was unknown If patient had Covid prior vaccination. But she had not tested Covid post vaccination.
