nausea; burping; diarrhea is watery, then soft, then hard, all kinds; gassy; pancreatic enzymes were 3 points higher than normal; it has aggravated her stomach problems; more like constipated; This is a spontaneous report from a contactable consumer (patient). A 65-year-old female patient received bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number: ER2613), dose 2 via an unspecified route of administration, administered in Arm Left on 17Mar2021 14:30 (at the age of 65-year-old) as 2nd dose, single for covid-19 immunisation. Medical history included ongoing gastrooesophageal reflux disease (GERD), nausea with the burping. Concomitant medications included famotidine (PEPCID). The patient previously took clindamycin and experienced itchy eyes and a rash. The patient previously received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number: EN6198) on 24Feb2021 10: 30 administered in arm left for COVID-19 Immunization. The patient experienced nausea, diarrhea is watery, then soft, then hard, all kinds, burping, gassy, pancreatic enzymes were 3 points higher than normal on an unspecified date. The patient who was 65 years old, had her shots of the vaccine last March 16-17. She mentioned that they experienced diarrhea, all kinds and form (liquid, mild to severe). She also said that they already filed a report with safety about this. She mentioned that after getting the vaccine, she had her bloodwork done and it showed 3 points increase than the normal pancreas enzyme level. The patient was calling about the Covid 19 vaccine. She and her husband have both received their second Covid 19 vaccines. She had hers on 17Mar2021. She reports she has been having nausea and diarrhea. Her diarrhea is watery, then soft, then hard, all kinds. She is asking if other people are experiencing this. She has had lab work done and a stool test. She doesn't know if it's related to the Covid 19 vaccine but her lab work showed that her pancreatic enzymes were 3 points higher than normal. When probing weight she reports she doesn't know if her weight is related to the pandemic or from being at home, her weight is 130 lbs. now but this time last year she was 147lbs. She thinks it started about 2-3 weeks ago after eating a meal, not when she's eating. She'll burp a little, she's gassy, and she has nausea. She thinks it has aggravated her stomach problems. She does have GERD. She's better now, she's improved only. The other day she went to the bathroom normal and then the next time she went to the bathroom her stool crumbled. She's never certain what will happen. This morning she went to the bathroom more normal, more like constipated. She doesn't know if later it'll explode. Meaning she doesn't know if later the diarrhea will come back. She reports when she experiences the nausea with the burping she takes Famotidine or Pepcid 10mg and that takes care of it. She's never had elevated pancreas levels before. She's been referred to a gastroenterologist. She reports she is allergic to clindamycin. She experienced itchy eyes and a rash. This happened about 3 years ago. There is no prior vaccinations (within 4 weeks), no AE following prior vaccinations. The AEs (nausea, diarrhea) require a visit to physician Office, tele visit. The outcome of "nausea, diarrhea is watery, then soft, then hard, all kinds, burping, gassy" was resolving, the outcome of the other events was unknown.  No follow-up attempts are possible. No further information is expected.
