Patient was enrolled in the study and in treatment at the time of the events. Patient received 2nd dose of the mRNA-1273 vaccine on 20-Feb-2021. On 22-Feb-2021, patient had fatigue and fever. In ER, patient complaint of fatigue, dyspnea, and body aches, and tachycardic above 100 bpm, dyspnea with exertion, with temperature 102.2 °F, BP high 90's, which met the criteria for sepsis. Relevant laboratory test showed decreased hemoglobin, hematocrit, elevated protein in urine, elevated C-reactive protein (CRP), SARS-CoV-2 test negative, Chest X-ray showed improved patchy opacity at the right lung base with improved small right-sided pleural effusion. Subsequently admitted to the hospital and started on Tylenol, Maxipime and vancomycin. On 23-Feb, reported worsening back pain increased with walking. A plan to discontinue his empiric antibiotics and monitor his blood cultures was made and his last dose of vancomycin was on (23-Feb), which he had been taking orally for 6 total weeks of treatment. And was discharged after 2 days of hospitalization. On 27-Feb, had fever, fatigue, and fall and re-admitted for treatment. Reported right upper quadrant abdominal pain that started overnight. On admission, patient was hypotensive, tachypneic, dyspneic on exertion and orthopneic, and with lower extremity edema and was found to have acute chronic anemia and acute kidney injury. The AKI resolved overnight after IVF and 1unit PRBC transfusion. Repeat hemolysis test and labs showed elevated haptoglobin, lactate dehydrogenase (LDH) fibrinogen and D-dimer, with recent deep vein thrombosis and started on anticoagulants. Lab tests showed decreased hemoglobin hematocrit, cloudy urine with elevated protein, low eGFR. On March1, patient was discharged feeling a bit better, and quite weak. The subject was following up for treatment after his recent discharge. The treating MD sent him to the emergency department to be evaluated for his continuing fever and fatigue. And was admitted on 05-March, presented with back pain, difficulty urinating, fatigue and concern for a sepsis alert and being worked up for active infections. PE findings included tachypnea, diminished breath sounds in the bases, mild abdominal TTP without rebound or guarding, trace lower extremities edema, rash. Patient was admitted to Medical Oncology with differential diagnoses of sepsis, UTI, intraabdominal infection, medication reaction, neutropenic fever. Lab test showed, turbid urine with signs of infection, with elevated protein; blood cultures were negative. On 07-March, subject was improving, while on antibiotics. Lab tests: Blood and urine cultures negative; gastrointestinal panel test normal, positive CMV IgM antibody test and EBV acute panel test IgG; given preliminary positive HIV and possible active CMV, no evidence of DVT in doppler, subject underwent a flexible sigmoidoscopy, thoracentesis. On 17-March, discharged from the hospital in stable condition and completed a 5-day course of Ceftriaxone and Metronidazole. Multiple co-morbidities could be considered as risk factors and concomitant Vancomycin and Losartan remain as confounders for acute kidney injury. The benefit-risk relationship of mRNA-1273 is not affected by this report. Events seriousness was assessed based on medical judgement.   This case was linked to MOD-2022-607859 (Patient Link).; Sender's Comments: This spontaneous case concerns a 71-year-old male patient, with relevant medical history of dyspnea, lower extremity edema, paroxysmal AF-controlled, GERD, hypertension, obese, hypokalemia, Barrett esophagus, obstructive sleep apnea syndrome, fatigue, and anxiety, with concomitant Vancomycin and Losartan, enrolled in the study and in the treatment at the time of the events, who experienced the unexpected serious medically significant AESI of Sepsis that occurred 2 days, AESIs Acute kidney injury and Deep vein thrombosis 7 days , and Urinary tract infection after receiving the 2nd dose of mRNA-1273 vaccine. Patient was enrolled in the study and in treatment at the time of the events. Patient received 2nd dose of the mRNA-1273 vaccine on 20-Feb-2021. On 22-Feb-2021, patient had fatigue and fever. In ER, patient complaint of fatigue, dyspnea, and body aches, and tachycardic above 100 bpm, dyspnea with exertion, with temperature 102.2 °F, BP high 90's, which met the criteria for sepsis. Relevant laboratory test showed decreased hemoglobin, hematocrit, elevated protein in urine, elevated C-reactive protein (CRP), SARS-CoV-2 test negative, Chest X-ray showed improved patchy opacity at the right lung base with improved small right-sided pleural effusion. Subsequently admitted to the hospital and started on Tylenol, Maxipime and vancomycin. On 23-Feb, reported worsening back pain increased with walking. A plan to discontinue his empiric antibiotics and monitor his blood cultures was made and his last dose of vancomycin was on (23-Feb), which he had been taking orally for 6 total weeks of treatment. And was discharged after 2 days of hospitalization. On 27-Feb, had fever, fatigue, and fall and re-admitted for treatment. Reported right upper quadrant abdominal pain that started overnight.
