redness at the injection site; slightly warmer than her upper arm; sore arm for a couple of days; This is a spontaneous report from a contactable consumer (patient). A 72-year-old female patient received bnt162b2 (Pfizer-BioNTech COVID-19 Vaccine, solution for injection), dose 2 via an unspecified route of administration, administered in right arm on 04Mar2021 (at the age of 72-year-old) (Lot Number: EN6205) as dose 2, single for covid-19 immunisation. Medical history included cancer surgery on an unspecified date in 2003 and unknown if ongoing, chronic lung issue, she had 14 lymph nodes removed out of her left torso and also cellulitis in her left arm from an unknown date and unknown if ongoing. Concomitant medications included lactobacillus acidophilus (ACIDOPHILUS PROBIOTIC) taken for an unspecified indication, start and stop date were not reported. Patient previously took first dose of BNT162B2 (lot number: EL9269) on 10Feb2021 for covid-19 immunisation. The patient experienced a sore arm for a couple of days from 04Mar2021 and redness at the injection site from 08Mar2021. She explained she then had a delayed redness popup on her right arm, where the vaccine was administered. She described the redness as a splotch and this area is slightly warmer than her upper arm from 08Mar2021. She specified it is a little bigger than the band aid that was covering the site. She stated she had it for 3 days and it is a little less red that day. The patient received the treatment for sore arm for a couple of days. The clinical course was reported as follows, Caller says here in (place name), she got the second Pfizer COVID vaccine on last Thursday, 04Mar2021, and nothing was unusual. She had a sore arm, but she iced it and moved it around a little bit, it was her right arm. But now, it has been a week since she got her vaccine, and two days ago she developed a big red splotch on her right arm on the deltoid area where her COVID vaccine was given. She looked all over the internet about delayed redness in arms and she only saw this information in reference to the Moderna vaccine but she got the Pfizer COVID vaccine, at least that is what her COVID card said. Confirmed with caller that where she received her COVID vaccine she was informed it would be sore similar to a flu shot. She was sore for a couple of days, but it was not unusual, she expected that. But she didn't expect the other surprise to pop up. She has friends who had COVID vaccines, she thinks they were Pfizers, and they said the same thing, their arms were sore. The soreness started immediately on the day of her COVID vaccine on 04Mar2021 and she had the sore arm until 06Mar2021. She had a little soreness residue on 07Mar2021 but it is all gone now. She is moving her arm now and there is no sense of a vaccination site there, just the redness and yesterday she noticed that more than she notices it today, it also seemed warm. She noticed this before going to bed on 09Mar2021 and she told herself that she would check if it was still there the next day before going to bed. It was there Tuesday and Wednesday and it is still there now. Where the big red splotch is, her arm feels warmer there. She says her arm being warmer and the big red splotch are both still there. She says it may be a little tiny bit lighter today than it was yesterday but it hasn't gotten worse. Probed if caller thinks it has improved or stayed the same since they bot began and she says that she can't really say. She takes no medicine, no antibiotics, thank goodness, she has been staying health. Her doctor had suggested that she start taking a baby aspirin 3 days a week and she stopped taking that Aspirin three days before receiving her vaccine. She can't think of anything, she takes a probiotic or a prebiotic, Acidophilus Probiotic everyday. The outcome of sore arm for a couple of days was recovered on an unspecified date in 07Mar2021. The outcome of other events was unknown.  No follow up attempts are possible. No further information is expected.
