hives/welts all over her body; She complains of itching; "really red" round spots, and that they are cropping up in different places; This is a spontaneous report from a contactable consumer (patient). A 79-year-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 MRNA VACCINE), via an unspecified route of administration administered in left arm at a pharmacy facility on 08Sep2021 (Batch/Lot number was not reported) (at the age of 79-year-old) as DOSE 1, SINGLE for covid-19 immunisation. The patient had no prior vaccination within 4 weeks. Medical history included chronic bronchitis diagnosed several years ago, sinus infection, hernia (she has to have a hernia fixed), hives (the caller went through hell for 15 years, she would periodically get hives if she had a medicine or something she was allergic to. That is why this is making the caller so nervous). The patient had no family medical history relevant to events. Concomitant medication included unspecified antibiotic for sinus infection. The patient previously took adrenaline [epinephrine] for hives. The patient got her first dose of bnt162b2 on 08Sep2021. A couple of days after (on unspecified date in 2021), she broke out in hives/welts all over her body. She said she experienced the same thing with other medications she's had an allergy too. Had for like 15 years, stopped. She reported hives on the left side, which was the side of the injection, then a couple of days later, she has one on right leg. She stated they are not like regular hives, more like welts. In previous experiences, they were under her feet, on top of her head, and her eyes would swell shut. She stated she would "get them inside," and when that happened, she ended up in the emergency room (ER) and they gave her adrenaline (not with the Pfizer vaccine; other things in the past). She was scared to death she will get them inside, and she felt like maybe that was happening again last night, but she did not go in. She complained of itching. Stated she has taken Benadryl and Claritin, but it was not really going away. Patient described them as "really red" round spots, and that they are cropping up in different places. The biggest one was on her right arm, about the size of half dollar. Patient said she has to have a hernia fixed, so had to get vaccine because she has to go to a hospital, so thought if she got the vaccine and got Covid, at least she would not get as sick. She was asking if this has been reported, how long it will last, and if she should get the second dose. She also asks how to get rid of them. The patient further reported that patient had the vaccine about a week and a half ago, on a Wednesday. A couple of day later, the patient started breaking out in hives. The patient used to get really bad hives a lot but this was different because its more like whelps and they started to go down. Now the patient has spots on her body that are round red and flat and they keep coming. The patient can't stop the itching. The patient was scared. The patient went through hell for 15 years, she would periodically get hives if she had a medicine or something she was allergic to. That was why this was making the patient so nervous. The patient can't stop itching. In the past, the patient would get hives from the bottom of her feet to top of her head and her eyes would swell shut. Finally it got to the point the patient wouldn't get them anymore until she took a medication that she would react to. A couple of day after the vaccine the patient got red whelps mostly on the left side of her body where she got the shot. A few days later the patient would get them a few more places but they wouldn't be raised, they would be flat. Right now they are flat red spots, a couple of them are a pretty good size. The patient used to get the hives inside of her body and she would have to go into the emergency room and get an Adrenaline shot. Patient asked if anyone else reported this and if she should get the second shot and how to get rid of them. The patient was supposed to go on the 28th or 29th for her second dose and doesn't want to. The patient had no relevant tests. The events did not require visit to emergency room, but noted that if the patient gets the tightness in her chest she may have to go. The events required visit to physician office. Therapeutic measures were taken as a result of the events. The final outcome of the events was unknown.  Information on the lot/batch number has been requested.
