A 76-year-old female patient received the first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 MRNA VACCINE, lot number: EL3249), via an unspecified route of administration at left upper arm on 26Jan2021 at 14:19 at SINGLE DOSE for COVID-19 immunisation. The patient had no previous immunizations. The patient had no prior vaccinations within 4 weeks and no additional vaccines administered on the same date. Medical history included allergic to penicillin, bladder infection, in the middle of her chest she had the pain cling through her back, and thyroid getting lazy and does not work. Concomitant medications included acetylsalicylic acid (BABY ASPIRIN), levothyroxine sodium (SYNTHROID) for thyroid getting lazy and does not work, vitamins, and sulfa drugs for bladder infection. It was reported that after getting the first dose of the vaccine the patient noticed she had pustules across her back on an unspecified date. The patient stated she "got this rash from the tips of fingers, even the palm of my hands and it starts right under the neck and goes across my breast, on my belly, on my back and both arms and is now halfway down my shin bone." On an unspecified date in Jan2021, she noticed this the afternoon of her vaccine around 7:00 when she saw two splotches on her stomach and it kept spreading. Sunday morning she went to Quick Care and yesterday went to her regular doctor. Her doctor gave her prednisone to take 10 mg 4 times a day, and hydroxyzine 10 mg for itching. In her throat she was getting hoarse on an unspecified date and was keeping a water bottle on her desk to keep hydrated. She stated she read on (website) that a rash can be a symptom of the vaccine. The caller asked, "if the pustules burst will this cause anyone to get Covid 19? Is this a possible side effect of the vaccine? How long will this last? Is it okay to get my second shot with this reaction? Is there anything I should be taking to make it go away?" It was further reported that patient received paperwork to call if there was any type of reaction. The patient mentioned she has a rash that was all over her body on 28Jan2021. It was on the top of her hands, in the palm of her hands, on her arms, back, under her breast, on her chest, on her stomach, on her bottom end, it was going down her legs and to her knees at this point. The patient initially stated she noticed the rash on Friday (29Jan2021), she later stated it was Thursday 28Jan2021 when the rash first started. She stated she first noticed splotches on her belly on her right side, right below her waist on an unspecified date in Jan2021. At first when looking at it she did not think too much about it. Later in the call she further clarified and stated it was possible she noticed these splotches the same day in the evening on the day she got the vaccine. She was not sure. If it was not the same day it was the next day. Friday (29Jan2021), she started to get as initially stated bumps, but later clarified rash under skin and it really proceeded from there. Additionally, it was reported that the rash continued to spread throughout her whole body. It was down to her shin now. Her whole upper body was horrible. She has some across her back. There are pustules on them like a pimple. It was like water in it ready to break. Sunday she went to a (clinic name) to get it looked at. She went Sunday 31Jan2021. She was given an intravenous (IV) and three needles were placed in it. She knows one was a steroid, she does not know what the other two were for, but she thinks one was probably for itching. The patient also confirmed she also experienced itching with the rash on 28Jan2021. It started the same day she noticed the rash. The patient stated it was like a full blown case now. The itching was with the rash on 28Jan2021. The itching and rash has continued to go down her body. It was on her buttocks now. It was hard to sit. It was in private up between her legs and stuff. Her body was almost 80 % full and covered with this stuff. She saw her regular doctor yesterday. The doctor at (clinic name) thought this reaction may have been an allergic reaction to a Sulfa drug she was taking for a bladder infection coincidentally at the same time, but she does not believe this was the case. Stated she had taken that sulfa drug before previously. She does not have the name of the drug to provide of the sulfa drug. She does not have it with her. No blood work was done. She was just looked at. They saw what was going on. The patient also mentioned she went on the internet to do research. She saw on Pfizer page three pictures that resembled what she had going on. It was also reported that the two splotches on right hand side started about 7'clock in the evening. At first did not think anything of it. Thought it was possibly a bug bite at first. Additionally, it was reported that patient went to see a doctor. She was already going to the doctor for a bone density scan and she showed the doctor what was going on at the same time. Her primary doctor thought this was due to the COVID 19 Vaccine. At end of call, patient questioned "if the pustules across upper back and behind neck, will that cause anyone to get COVID 19? Side effect?" The patient had no emergency visit. Therapeutic measures were taken as a result of itching with the rash, rash that is all over her body, and two splotches on right hand side. The patient had not yet recovered from rash that is all over her body while outcome of the events pustules, itching with the rash, in her throat she is getting hoarse, and "splotches on her belly on her right side, right below her waist /Two splotches on right hand side" was unknown.
