A 62-years-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, Batch/Lot Number: EN6206 and Expiration date: unknown) via an unspecified route of administration, administered in left arm on 12Mar2021 02:00 (at the age of 62-years-old) as dose 1, single for covid-19 immunization. The patient medical history included breast cancer from Sep2001 and unknown if ongoing. Patient stated she has had reactions to some antibiotics, and the only other thing is that she does not get the flu vaccine so she cannot compare them. Patient stated that the only thing else she had reaction to, which was maybe normal, was that there was a breast cancer chemo drug that she had a reaction to that they still gave to her at a lower rate. It was reported that the reaction happened during treatment, and she found out she had a lot of different reactions to medications, like Darvocet and pain things, and antibiotics that bothered her. Reporter stated for the Taxol she does not know if that was a reaction, it was not full blown to where she could not use it, they just gave it to her at a slower rate. No further details provided about antibiotics or pain medications. Concomitant medications included dextropropoxyphene napsilate, paracetamol (DARVOCET) NDC/LOT/EXP: Unknown; taxol NDC/LOT/EXP: Unknown. Reporter stated that she and her daughter (34 years old) both received the Pfizer covid vaccine, first dose, on 12Mar2021, and experienced injection site pain, swelling, redness and large welt. Patient said they do not have it now but they both had them after the vaccine. Patient also experienced arm soreness, neck tightness, itching and achy. Patient stated that they had a reaction and went to pharmacist for second shot both for her daughter and her, they both had a reaction the first time around, but was turned away because the HCP was worried it may be worse than the first allergic reaction. Patient reported that the pharmacist gave them a number to call to discuss this with Pfizer so they could get advised because they feel it could be an allergic reaction, and they were wanting to make sure they could be given second shot. Patient stated that the pharmacy basically turned them away, and they did not get their second shot today. Patient reported that their first shot was three weeks ago, 12Mar2021 around 02:00PM. Patient stated that when her reaction began it hurt obviously right away, then it got red with like a welt, after she got home for sure. She stated that it took about hour to get home from there, then later in evening and overnight it got more of a welt. Patient stated that she did not receive any treatment, she just took a shower and let water run on it and that was it. It got really sore and kind of stayed that way for 2-3 days, the redness grew and got bigger, and welt got bigger. She stated that the welt was not as big as the red area and analogy they have been using is the red area was around the size of a hamburger bun, just the redness. She said that the welt underneath was hard, raised, firm to the touch, and sore to the touch. Patient stated that they had a few other side effects and this only happened to her, and it went away after 4 days or so, but day 10 the bump came back and it was not quite as big a bump, but it hurt with a red lump underneath it, and when she moved her arm it was achy. She stated that all that she felt like was it was also in her neck a little bit and the back of neck and shoulder were sore and honestly her arm was still a little achy after 3 weeks. She clarifies that the injection site for both of them was where all lumps and redness were. Patient stated that one other thing was that her injection site was itchy, but this was not true for her daughter and hers was red like that, it was not horrific, but it was definitely itchy, she scratched it and was like what was going on, and after she scratched it, it was all red again, which lasted two days then went away again, maybe a little longer than that, 3 days. Patient daughter stated that her elbow was really sore for 5-6 days, and she was very tired, which was a thing that was a common side effect and slept for hours and hours. she also stated that the main thing that was out of the norm was the red bump, swelling or welt, and redness. Patient stated that her daughter's reaction lasted longer, the redness and lump, they lasted 5-6 days, and hers went away. Patient stated that hers came back but her daughters did not. Patient wanted to know the efficacy of the first dose, the time frame for the second dose, would it be less effective if taken later then, 21 days, what were the chances of them getting an allergic reaction and also would like to know if they should get the second shot. Outcome of the event injection site itching was recovered and the rest events were unknown.  No follow-up attempts are possible. No further information is expected.
