had lost a lot of weight; Blotchiness on my arms/Red blotches on the insides of her arm; swelling in fingers and toes; Closeness in breathing; felt like she was going to have a general allergic reaction; Tingling; burning sensation on her skin; itchiness; Chest discomfort; This is a spontaneous report from three contactable consumers (patient, patient's son and patient's husband) via Medical Information Team. A 70-year-old female patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection) intramuscularly to her upper right arm on 21Jan2021 (age at vaccination) (Batch/Lot number: EL3246, NDC number/Expiry date: Unknown) as single dose for Covid-19 immunisation. The patient's medical history included visual issues (had been dealing since before the vaccine). The patient was allergic to penicillin, sulfa medication, neomycin and iodine (all are ongoing). Additional information for other conditions included for years. On 21Jan2021, the patient felt like she was going to have a general allergic reaction, red blotches on the insides of her arm, tingling, burning sensation on her skin, swelling in fingers and toes, itchiness, and chest discomfort/breathing closeness. She had the vaccine on 21Jan2021. She felt okay the rest of the day. Then, 8 hours after the vaccine, she started to feel off. She had allergies, and she felt like she was getting general allergic reaction symptoms. The ones that she sometimes gets. She monitored it. Before bed, she took Benadryl to stave off any allergic reaction. Since then, she still gets some of the sensations of a reaction on and off. She has been taking Benadryl on and off for the last couple weeks. She had visual issues, but she had been dealing with that since before the vaccine. She had lost a lot of weight. She was unsure of her weight, but if she had to guess approximately 115lb. She did not have a prescribing doctor. It all started approximately 8 hours later. She had an inhaler. She looked at her arms, and there were red blotches on the insides of her arm. She experienced tingling. She felt her skin which felt like a burning sensation. There was a little bit of swelling in her fingers and toes. Some of it came back every time she feels it coming on. The skin sensation especially came back. She had been using an Inhalant and taking Benadryl. She had been using the Benadryl more than the inhalant. She got the vaccine because her husband pushed her. She had fair amounts of pressure to get it. She had concerns because of her allergies. She did ask if any of the things she was allergic to were in the vaccine, and she was told no. The few she knew she was allergic to were not in the vaccine. She was still concerned. She eventually decided to take it. She was concerned/worried about the second dose. She was scheduled for Monday. She was allergic to penicillin, sulfa medications, neomycin, and Iodine. The time frames varied actually. She has been allergic to sulfa drugs for years. She also had some itchiness here and there. She had chest discomfort to. She had to use her inhaler because of closeness in her breathing. It was a heaviness in her breathing. The first time it popped up it was not that bad, but it had happened a couple of times. Outcome of the event had lost a lot of weight was unknown, whereas other events was not recovered. No PQC present.  Information on the Lot/batch number has been requested. Follow-up attempts are completed. No further information is expected.
