The clinical details of the events as follows: Caller is a 72-year-old female who received her second dose of Pfizer COVD-19 vaccine on Friday. She reported a rash an inch below the injection site. The rash is red in color, tender, warm to touch and itchy. She noticed it was not as tender or warm and started to change color from red to light pink. It was oval in size with no bumps. She stated that her arm was more sore than after the first shot, but did not have to get medication. The caller was wearing a long sleeve top on Sunday and noticed her arm felt kind of itchy, and she thought, oh it was just the shot healing. Last night when the caller took a shower, she noticed that her arm had a red patch, not where the shot went in, about 1 inch below it. It was a round area that is red, not a deep red, but red. The red area was on the upper part of the upper arm. It was just itchy, red and warm. The area felt tender and red and warm yesterday, but today if she put her palm on it, it felt warm and was red but not tender. The caller noticed it still feels kind of warm, not as warm or tender like yesterday. When the caller got the vaccine, she received the fact sheet, but it did not mention an arm rash. Online the caller saw they were talking about the Moderna vaccine saying it can cause the covid arm, but not Pfizer. The caller was really happy after the vaccine, she had a slight mild headache but nothing that she needs to take a nap for, she expected that. The caller did not have joint aches or fever. The rash was on her arm right below where the injection went in, the upper skin of the upper arm. There was a big red patch, not like the normal skin color, red, 6 inches across and 4 inches down in size, shaped like an oval. It was on the patient right arm. The rash was noticed on an unspecified date (yesterday) though the area was itching on Sunday. It has improved a little; it still itching and is warm but not as warm. Also, it may slightly be lighter in color. It is hard for the caller to tell because she was looking at it under lighting last night. She noticed the rash last night. This event happened after the second dose of the vaccine. The AE(s)did not require a visit to Emergency room and Physician(s) office. Relevant Tests were none. There was no Investigation Assessment performed. Caller read some information online related to the COVID-19 vaccine. She said rash has been reported post moderna second dose vaccination and not with Pfizer. Moderna recommends using over the counter hydrocortisone cream cream to reduce rash. They suggest rash was not harmful or critical if it gets worst it should be reported. Caller wanted to verify if the information she read regarding the Pfizer vaccine is accurate. The patient outcome of the event red patch on arm was resolving, the event arm felt kind of itchy was not resolved and the outcome for other events was unknown at the time of this report.  No follow up attempts are possible. No further information is expected.
