he got two of the same product, in two different arms, at the same time; there are lumps there and sore places and there is still a lump and it is still sore, particularly on his left arm, not so much his right, but left arm is still sore; there are lumps there and sore places and there is still a lump and it is still sore, particularly on his left arm, not so much his right, but left arm is still sore; lethargic; feels sleepy; low energy; feeling lousy; This is a spontaneous report received from a contactable reporter(s) (Consumer or other non HCP) from medical information team. The reporter is the patient.  A male patient received BNT162b2, BNT162b2 omi ba.4-5 (BNT162B2, BNT162B2 OMI BA.4-5), as dose number unknown (booster), single (Batch/Lot number: unknown), in arm for covid-19 immunisation. The patient's relevant medical history and concomitant medications were not reported. Vaccination history included: Covid-19 vaccine (Primary immunization series completed, Manufacturer: Unknown), for COVID-19 immunization. The following information was reported: MALAISE (non-serious) with onset 28Nov2022, outcome "not recovered", described as "feeling lousy"; INCORRECT DOSE ADMINISTERED (non-serious), outcome "unknown", described as "he got two of the same product, in two different arms, at the same time"; VACCINATION SITE PAIN (non-serious), VACCINATION SITE MASS (non-serious), outcome "not recovered" and all described as "there are lumps there and sore places and there is still a lump and it is still sore, particularly on his left arm, not so much his right, but left arm is still sore"; LETHARGY (non-serious), outcome "not recovered", described as "lethargic"; SOMNOLENCE (non-serious), outcome "not recovered", described as "feels sleepy"; ASTHENIA (non-serious), outcome "not recovered", described as "low energy".  Additional information: Reporter was calling about the COVID vaccine booster dose, but the reporter provided with the name as the updated booster Pfizer. He stated it was the Pfizer COVID vaccine. When tried to confirm if he was referring to the Bivalent booster, he stated that was a good question because the person at Withheld who wrote the info on his vaccination card did not write it 100% legibly and wrote updated Pfizer booster GN9703 He wanted confirmation if that corresponds to Pfizers products but after offering to speak with customer service to check for him he declined and stated he wanted to assume it was. He confirmed that his question was that he got side effects and wanted to know how to deal with the side effects for the product. Regarding his side effects, he stated they gave him a shot in each arm and there are lumps there and sore places and there was still a lump and it was still sore, particularly on his left arm, not so much his right, but left arm was still sore. He spoke with Withheld about this and they told him it was the same product in both arms so he does not know why his left arm would be more sensitive than the right but nonetheless that was what it was. He received both at the same time. Based on what he was told by Withheld he got two of the same product, in two different arms, at the same time. He stated when they gave the shots they did not pull the vaccine from the same vial/source/glass container for both arms, they used a different vial on left than they did on the right. Reporter stated that on the little card that he got at the drug store it has the product name of Booster GN9703. Wanted to know does Booster GN9703 correspond to anything Pfizer sells. Wanted to know does the agent not know the Pfizer product or what it was that he was talking about. Reported that ever since he had got the shot that he has been feeling lousy. Stated that it was since 28Nov2022. Has been living with it. Started out that he had lumps where he got the shot in both arms and that stayed with him throughout Jan. Still has sore places on his arms where he got the shot. Feels lethargic, feels sleepy and has had low energy for like a month now. Does not know what was going on. Thought perhaps Pfizer at this number would be of some assistance. Was administered from Withheld. Clarified that the product was listed as the updated Booster Pfizer GN9703. Was wondering in the system was it identified as a Pfizer code number that one can reference the product involved and know how to deal with it specifically in detail.  The information on the batch/lot number for BNT162b2, BNT162b2 omi ba.4-5 has been requested and will be submitted if and when received.
