She was not using heart medications. Clostridium difficile from Mar2020 a year ago at the end of Mar2020, first part of Apr2020. It was unbelievable what the C. Diff did to her. She took Keflex for a very mild urinary tract infection. She took the Keflex for 10 days and she was fine until she got the C. Diff. She never really recuperated from it. She had the C. Diff and that's why she had the weight loss She was told an antibiotic can cause C. Diff. She knew people who got C. Diff after taking an antibiotic. When she got the C. Diff she ended up in the hospital. The patient's family medical history included that her husband was given an antibiotic and he developed C. Diff before his surgery on something. The patient's concomitant medications were not reported. The patient was not related to any study or programme. It was reported that it was unknown if he had taken other products. Vaccination facility type reported as medical building and not military facility. The patient had no history of all previous immunization with the Pfizer vaccine considered as suspect. The patient had neither received any other additional vaccine was administered on the same date of Pfizer vaccination nor within 4 weeks prior to the vaccination. The patient had not AE(s) following prior vaccinations. Historical vaccine received BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Solution for injection, Lot Number: EN6206, Expiry Date: 30Jun2021) via an unspecified route of administration in left arm on 01Mar2021 as Dose 1, Single (at the age of 70 years old) for COVID-19 immunization. She experienced a rash she's had for about a week. The rash all of a sudden appeared after her Covid 19 vaccinations. Her right arm was more affected, and she received her Covid 19 vaccines in her left arm. All of a sudden, she had a red, raw rash going up her right arm and it's kind of swollen at times. She's been putting hydrocortisone cream on it. She usually doesn't get rashes. She wished she would have called to report it before. Received 2nd dose of covid vaccine about 2 weeks ago. After vaccine said developed rash scattered from wrist to elbow. HCP did prescribed ointment. Would like to know to manage rash, if we have suggestions. She was maybe a little tired the next day. She doesn't remember exactly. She first noticed the rash on Thursday of last week, 08Apr2021. She thought it was poison ivy at first. She's been treating the rash herself for the itch. At time of reporting, the rash was calm but when she goes to sleep at night and wakes up in the morning her body swells up a little bit and the rash looked worse. The rash originated on her right side and now she's a little rashy on the left arm. She had a few rashes behind her leg, but the worse part was on the inside of the right arm from her hand to the inside of her elbow/ red, raw rash going up her right arm. She's been using hydrocortisone 10 maximum strength ointment. There was a number on the front of the tube 20L109, and the back of the tube was the expiration date 10Oct2023. She needs use a magnifying glass to see the numbers on the hydrocortisone tube.  She though the rash was in her blood stream and not just a contact rash. She used to work in a hospital, and she remembered handling things and talking about things in the human body. She reported her rash was not a contact rash because she didn't contact anything. She could tell it's not a contact rash because the rash was coming from the inside of her body. She believed the rash was caused from the Covid 19 vaccine. She reported she went to her doctor for an appointment that was already set up for a physical. She reported her heart and blood pressure was fine. Her doctor wasn't sure about the rash. He prescribed a cream and told her just to keep an eye on the rash. The cream that he prescribed was costly. If what she had was just a rash then it's cheaper for her to use the Cortisone 10. If she doesn't need the cream her doctor prescribed, she's not going to pay for it. Her rash was not itching right this minute. If her rash doesn't get better than she'll get the cream her doctor prescribed. She knew the rash was from the Covid 19 vaccine. She even called her dermatologist just to see and the dermatologist said because the Covid 19 vaccine was so new, there's no way to know for sure if her rash was caused by the vaccine. Her dermatologist didn't felt comfortable prescribing any medications. She did not seen her dermatologist in a while. She asked if the rash would go away eventually and when she would heal or dissipate from rash. These events did not resulted in Emergency Room visit. The patient visited physician office for rash. No relevant lab test was reported. No investigation assessment was reported. The clinical outcome of events red, raw rash going up her right arm, swollen at times, her body swells up a little bit and the rash looks worse, worse part is on the inside of the right arm from her hand to the inside of her elbow was not recovered (ongoing) while that of remaining was unknown.  No follow up attempts are possible. No further information is expected.
