injection site started itching; Strange area around injection site about size of silver dollar, red around outer rim and kind of orangeish colored in the middle; Strange area around injection site about size of silver dollar, red around outer rim and kind of orangeish colored in the middle; feel extremely unwell; feverish 97.5-97.6 degrees Fahrenheit; tired; This is a spontaneous report from a contactable consumer (patient). A 92-year-old female patient received the first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number: unknown), via an unspecified route of administration (upper arm) on 20Jan2021 11:00 (at the age of 92years) at single dose for Covid-19 immunization. Medical history included breast cancer, second right breast lumpectomy related to breast cancer from 16Oct2020 to an unknown date, first right breast lumpectomy related to breast cancer on an unknown date (done about 3-4 years prior to second right breast lumpectomy related to breast cancer), on blood thinner, allergic to the statins and allergy to unknown product (She was once given something, some medication for her heart, but about 5- 6 weeks later she developed a reaction to it so she was taken off the medication but does not remember the name of the drug.) The patient would consider herself obese at this weight, but that is probably because she was always very thin historically; her doctor has never diagnosed her as being obese or advised her to lose weight. The patient's daughter had a very, very aggressive form of breast cancer-she is deceased 11 years. Patient's younger sister had breast cancer; there is a lot of breast cancer on her husband's side- his mother, sister, niece all had breast cancer, they have a big history of breast cancer; other types of cancer in patient's family include her mother who died of pancreatic cancer in her 80s; and her dad had prostate cancer but he was in his upper 80s; and patient's older sister died of leukemia. Concomitant medications included warfarin from an unspecified date at 5 mg (daily x 2 days/week) then 2.5 mg (daily x remaining 5 days/week) as blood thinner and metoprolol from an unspecified date at 25 mg, 2x/day (morning and evening) for an unspecified indication. The patient previously had Flu shot. The patient reported that she got on last Thursday (21Jan2021) the first dose of the Covid 19 vaccine at 11 o'clock. She did not feel anything wrong at the moment (also reported as she had no immediate reaction at all). A couple of days after (About maybe 2-3 days later sort of in the middle of the day, not the morning) she started to feel extremely unwell, feverish (although thermometer did not indicate any raise) tired and malaise she was really surprised because it occurred that long after administration. She took Tylenol and she was looking to know if this has been reported as a side effect of the vaccine and how to treat it. She was very concerned about it because she has never had an adverse event with any vaccine or inoculation before. She takes a yearly flu shot and never had any reaction. Feverish: She has taken her body temperature with her digital thermometer which does not show a fever, it shows like 97.5-97.6 degrees Fahrenheit so not a fever; but she feels feverish. On 26Jan2021 the injection site started itching and she looked at site which is way up high so she can't turn her neck that way; but found a strange area around the injection site that is about the size of a silver dollar, red around the outer rim and kind of orangeish colored in the middle. She has never had that occur before, and the skin in the middle of the area, the orangeish colored area has no pain. She reported that there was a mass of people at the location where she was administered the Pfizer COVID-19 Vaccine. There were hundreds of people there when she was for inoculation event so she is wondering if she could have picked up COVID while there. She called to ask about these events related to the product.  She has no major allergies. The patient underwent lab tests and procedures on an unspecified date which included body temperature: 97.5-97.6-degree Fahrenheit. The outcome of events was unknown.  Information on the lot/batch number has been requested.
