Clinical course: Calling about Pfizer COVID vaccine and the Pfizer COVID boosters and he had reported this information that after his 2nd dose he thought itching was a side effect and he has that on file and after that, now it is probably to the top level of boosters that he has had and where he is supposed to be and the condition of itching has increased dramatically and he has the skin condition to his forearms and it accelerated enough that it looks like if you are on a blood thinner where you have those kind of skin necrosis only he is not on a blood thinner. He is seeing a dermatologist. Has no report reference number and does not recall if he was provided one for the initial report. He got the vaccines while they were mandated and to show proof he still has his patient cards. All of his COVID vaccines were Pfizer COVID vaccine and the 1st dose was administered on 19Mar2021 with lot number EP6955 and the itching did not start until the 2nd dose for the itching and now this skin pattern where it is easy to bleed started much later and he has patching that was there he thought from the itching. His patient card has no expiry dates or NDC numbers written on it; states for his 2nd dose it was administered on 09Apr2021 with lot number EWD but it is poorly handwritten and it is C or 0 and maybe the numbers are 0151. Then what may be his last booster was administered on 16Jun2022 with lot number FJ4991 and that is the most recent and then later clarified he did have another dose on 23Oct2022 with lot number that is pretty hard to read and looks something like an H or looks like 4H but could maybe be GH703 if it follows the pattern of the other lot numbers on his patient card or if they may have changed the pattern of the lot numbers from being two letter characters and then the numbers. He clarified he also had one more dose which was on 30Oct2022 but he does not know what the lot number is as he states Withheld does not provide that and his card was misplaced. The itching increased dramatically and he does not know when it began to increase dramatically but guesses it is when he first noticed it was just there and did not notice it being increased but noticed as of late there is a larger pattern of bruising, bleeding and patching that is bruised. Asks if there were two COVID doses and then two or three booster doses and declined transfer and states he was just asking himself that for how many he had had.; Sender's Comments: Linked Report(s) : US-PFIZER INC-202300290354 same patient/vaccine/event, diff dose;US-PFIZER INC-2021412848 same patient/vaccine, diff dose/event;
