The following information was reported: FATIGUE (hospitalization) with onset 20Jan2021; IMMUNISATION REACTION (hospitalization) with onset 20Jan2021, described as "Severe adverse reaction to 2nd dose of Moderna COVID-19 vaccine"; ABDOMINAL PAIN (hospitalization) with onset 21Jan2021; PYREXIA (hospitalization) with onset 21Jan2021, described as "Fever"; NAUSEA (hospitalization) with onset 21Jan2021; VOMITING (hospitalization) with onset 21Jan2021; ARTHRALGIA (hospitalization) with onset 22Jan2021, described as "Arthralgias"; HYPOKALAEMIA (hospitalization) with onset 22Jan2021, described as "Hypokalemia"; LEUKOPENIA (hospitalization) with onset 22Jan2021; MUSCLE SPASMS (hospitalization) with onset 22Jan2021, described as "Muscle cramping"; MYALGIA (hospitalization) with onset 22Jan2021, described as "Myalgias"; CHILLS (hospitalization) with onset 22Jan2021, described as "Severe chills"; DIZZINESS (hospitalization) with onset 22Jan2022; HYPOTENSION (hospitalization) with onset 22Jan2022. Clinical course: On 20Jan2021, the participant received her second dose of Covid-19 vaccine, reported as the Moderna vaccine. One year later, on 20Jan2022, the participant received an additional vaccine dose (manufacturer not identified). On 22Jan2021, two days after having received her second vaccination, the participant presented to the hospital with complaints of nausea, vomiting, fever, and abdominal pain. Subsequently, she was admitted into the hospital for symptomatic management. The participant reported that after having received the second vaccine dose, she experienced fatigue; however, on 21Jan2021, the day after her second vaccination, she became febrile at work in the early afternoon. She also began experiencing bilateral abdominal pain that started on her sides and wrapped from her lower back around to the front of her abdomen. The abdominal pain came in 'waves' and led to dry heaves, nausea and vomiting. The participant reported that she experienced approximately ten episodes of dry heaving and non bilious vomiting. She was unable to keep any food, drink or medication down. The participant reported that overnight she developed bilateral myalgias and arthalgias throughout her upper and lower extremities. In addition, she experienced severe chills that led to muscle cramping. She complained of dizziness with standing and sitting but denied shortness of breath, chest pain, headaches, dysuria, and hematuria. At the time of admission, the participant reported that for the past couple of weeks she had noted abdominal discomfort. She attributed this to increased stress at work for the previous month with a resulting increase in carbohydrate diet She explained that due to her bariatric surgery, she normally avoided heavy carbohydrate foods. She endorsed frequent non-bloody bowel movements and diarrhea; however, she noted that since her bariatric surgery she experienced looses tools and had no recent change in her bowel habits. Upon physical examination, the participant was alert, oriented and in no acute distress. Her lungs were clear bilaterally to auscultation and she exhibited normal respiratory effort. Her heartrate was normal with a regular rhythm. Her skin was warm and well perfused. Her abdomen was non-distended with normal bowel sounds; it was tender to deep palpation bilaterally. Vital signs included: temperature 37.1 degrees Celsius, heart rate 50 beats per minute, respirations 16 breaths per minute, blood pressure 92/59 mmHg and oxygen saturation 97 %. A peripheral intravenous line was inserted and she was admitted for further management. Laboratory and diagnostic tests were obtained (see results below). During admission she received paracetamol (TYLENOL) (also reported as ACETAMINOPHEN), ondansetron (ZOFRAN), and 40 mEq of potassium chloride. She received four liters of fluid during admission. On 23Jan2021, the participant was discharged. Physical examination at time of discharge revealed her to be alert, oriented and in no distress. She remained afebrile and vital signs included: pulse 58 beats per minute, respiratory rate 20 breaths per minute, left upper arm blood pressure (sitting position) 115/74 mmHg and oxygen saturation 97 %. Her lungs were clear bilaterally, heart rate was normal with regular rhythm; bowel sounds were normal; no abdominal distention. No epigastric tenderness. Her skin was warm and well perfused.

Physician assessment: "Likely an immune response to COVID vaccine. Patient appeared to have a severe adverse reaction to second dose of Modema COVID-19 vaccine. Recommend attention to adverse reactions with future vaccines." Diagnosis/clinical impression: Abdominal pain; generalized fever, unspecified, unspecified hypotension. The action taken in response to the event for BNT162b2 was not applicable. The outcome of the events "fatigue", "fever", "abdominal pain", "nausea", "vomiting", "myalgias", "arthralgias", "severe chills", "muscle cramping", and "dizziness" was unknown. The outcome of the events "severe adverse reaction to 2nd dose of moderna covid-19 vaccine" and "hypotension" was recovering. The outcome of the events "leukopenia" and "hypokalemia" was recovered on 23Jan2021.   The reporter considered "severe adverse reaction to 2nd dose of moderna covid-19 vaccine", "fatigue", "fever", "abdominal pain", "nausea", "vomiting", "myalgias", "arthralgias", "severe chills", "muscle cramping", "dizziness", "hypotension", "leukopenia" and "hypokalemia" related to BNT162b2, but unrelated to concomitant drugs.; Sender's Comments: Based on the information in the case report, a possible causal relationship between the reported events and the suspect drug BNT162B2 cannot be completely excluded.  The impact of this report on the benefit/risk profile of the Pfizer drug is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events. Any safety concern identified as part of this review, as well as any appropriate action in response, will be promptly notified to Regulatory Authorities, Ethics Committees and Investigators, as appropriate.
