Clinical narrative: **Incorrect vaccine administered; no adverse reaction as of 12/27/2023 2:25pm**  On 12/26/2023 between 1:30pm and 2:00pm, pt. visited technician 1 at the pharmacy for a flu vaccine, but the pharmacy was closed for lunch. He was asked to return at 2:05pm when we would open back up from lunch. At 2:10pm he returned to fill out immunization paperwork with technician 2 . When pt. asked for the form, he asked technician 2 which COVID vaccines we had in stock and the technician 2 answered with "Novavax, Pfizer, and Moderna". He filled out the paperwork and the technician 2 asked which COVID vaccine he wanted, if he wanted Pfizer again, and he confirmed that he previously received Pfizer, and requested technician 2 to spell "Pfizer" for him. Neither the technician nor the patient remembers exactly how the conversation took place, but both confirmed he inquired about which COVID vaccines we had in stock and the technician asked him about which one he wanted.   Once pt. completed the paperwork, he returned it to technician 2 who asked technician 3 to process the paperwork for a Pfizer COVID vaccination. The state immunization shot record was reviewed by the pharmacist, the immunization was verified, and the paperwork was processed to will call for Comirnaty. Pt. was signed out at the register for Comirnaty and was brought into the immunization room.   Pt. was asked by pharmacist which arm would he like to receive the vaccine in, and he responded his left arm. Pt. was asked if he had any side effects to his previous Pfizer vaccination, to which he responded no. Pharmacist asked pt., "Pfizer, correct" and he stated "yes". Pharmacist explained since he did not have any reaction to the prior Pfizer dose it is possible he would not have a reaction to this dose, but explained possible side effects that may occur. Pt. and pharmacist had a conversation about his previous vaccines he received and the side effects he received from them. Comirnaty was administered in his left deltoid using the triangular method without complaint.  Later that afternoon around 4pm, pt. called the pharmacy and spoke with Technician 3. Pt. stated he visited the pharmacy earlier that afternoon for a flu shot however his paperwork states he received a COVID vaccine. The technician 3 asked the pharmacist to take pt.'s call, and pharmacist confirmed Comirnaty was administered to him. He stated he came in to receive the flu vaccine. Pharmacist immediately apologized and discussed the conversation with him in the immunization room. He stated he wondered why staff/the form asked him so many questions regarding the Pfizer vaccine. Pharmacist apologized again for the miscommunication and asked if he could come back to the pharmacy so we can administer the flu vaccine for him.  Pt.'s paperwork was processed for the flu vaccine and was ready for his arrival. When pt. arrived, pharmacist asked to explain what happened when he filled out the paperwork. He couldn't recall exactly, but stated he originally came to request a flu shot while we were closed for lunch. He remembers when we returned from lunch he asked the technician which COVID vaccines we had in stock. He filled out the COVID Immunization paperwork and agreed our conversation in the immunization room was in regards to COVID vaccines; however, pt. stated he wondered why staff kept asking about COVID and thought this was the new normal procedure within healthcare due to the pandemic. He stated when pharmacist confirmed Pfizer with him, he was under the impression that he was confirming he previously received Pfizer, not that pharmacist was going to administer Pfizer. I apologized again for the error and pt. stated we both could have been more effective with communication and he should have realized he filled out the COVID form. Pt. was signed out at the register for Flucelvax. Pharmacist brought him back to the immunization room, apologized again for the miscommunication, asked which arm he would like to receive it in, he stated the left arm again. After showing him the Flucelvax syringe, pharmacist administered Flucelvax into his left deltoid using the triangular method. Once completed, he requested a small sticker for the COVID vaccine he received earlier so he can update his COVID immunization card he left at home. He was provided a sticker and the Flucelvax paperwork and instructed if he had any further questions/concerns to give pharmacy a call. He left the pharmacy without further complaint.
