Clinical narrative: Vomiting; Diarrhea; lost alot of weight; diverticulitis; brain fog, can't think clearly; stomach pains; violently ill; This is a spontaneous report from a contactable consumer (patient). A 72-year-old female patient received the first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE), via an unspecified route of administration on 02Mar2021 (Batch/Lot number was not reported) as SINGLE DOSE for covid-19 immunization. The patient' medical history and concomitant medications were not reported.  The patient experienced vomiting and diarrhea. Mostly diarrhea. The vomiting started 05Mar2021 in the middle of the night. She was vomiting so much she went to the Emergency room by ambulance. They kept her in the hospital for a couple of days, but she did not have diarrhea at this time. It was like three days later that she suddenly became violently ill. At the time she did not tie it to the vaccine administration, she thought she had food poisoning or something. She then had severe diarrhea. She cannot recall the exact onset date of when the diarrhea began. She can't get the dates together because she knows she became very sick. Patient recalls that when she got out of the hospital, she was having stomach pains. The stomach pains were feeling more severe on 18Mar2021. On 19Mar2021, she went to a check up with her gynecologist for an annual check up and did tell her gynecologist about the stomach pain and having a lot of stomach issues, but the doctor had no idea about it, she's a gynecologist. The patient's gastroenterologist thought maybe she had diverticulitis not related to the Pfizer COVID-19 vaccine and on 27Mar2021, they started her on Cipro and Flagyl, but the diarrhea just kept getting worse even with the meds and its just been getting worse and worse and worse. Cipro and Flagyl were stopped after 5 days because her gastroenterologist told her that maybe all of her flora was cleared out, and the flora was causing the diarrhea. No one knows what was causing her diarrhea.  Oddly enough, she was feeling a little better today. She feels like she doesn't have diarrhea today, but she doesn't know because sometimes she has diarrhea for a couple of hours and then she feels just fine for a couple of hours. She also has brain fog. She was feeling like she could not think straight. She confirmed she does not have this feeling today. It got really bad after the second shot. The brain fog started between the time of first and second shot, when she had the diarrhea. It was like a week to ten days after the first shot, but she does not know exactly when brain fog started. It comes and goes, doesn't have it right now, and didn't have it yesterday. She stated that the brain fog seems to have gone away about 5 days ago. She had all these blood tests and cat scan and they all came back negative that she is in perfect health. She has no other issue except this constant diarrhea. Caller states she doesn't have any issues with any of her abdominal organs, her gall bladder and intestines are all fine. She has lost 5 pounds explaining that a month ago she weighed 136 pounds and now she weighs 130 pounds. The diarrhea is without any known medical known ideology and is very debilitating because she has lost a lot of weight. The outcome of events was reported as "unknown".  Follow-up attempts are completed. The following information on the batch number has been requested.
