On 16-Jan-2024, the subject stopped with prednisone.  At the time of follow up reporting, on 08-Apr-2024, the subject had not recovered from the event of atrial fibrillation.  No additional suspect drugs.

Narrative updated accordantly.   Linked Case ID(s): US-BEH-202401133, US-BEH-2024176616 (same patient) 04-OCT-2024 (System Update): Linked Case ID(s):202401133 (Patient Link); 2024176616 (Patient Link); Reporter's Comments: A 77-year-old subject was vaccinated with the blinded study vaccine aQIVc HD vs QIVr vs aQIV. On 07-Jan-2024, one month and 11 days after receiving blinded study vaccine, the subject was presented to the emergency department due to worsening dyspnea on exertion for the past three days. The subject also had had intermittent chills. The subject reported that back on 13-Dec-2023 he had a car versus pedestrian accident and was ran over and sustained left rib and back injuries. The subject was actively wheezing and desaturated to 80% on room air. The subject received several doses off nebulization. The subject developed atrial fibrillation with rapid ventricular response and was given Cardizem bolus (diltiazem) and oxygen. Medical doctor recommended admission for pneumonia and atrial fibrillation with rapid ventricular response. The subject started with doxycycline and Rocephin (ceftriaxone sodium), intravenously, daily, for acute pneumonia. On the same day, the subject had acute severe COPD exacerbation, acute hypoxic respiratory failure and sepsis. Four days later, on 11-Jan-2024, the subject was discharged from the hospital. The discharge diagnoses were acute severe COPD exacerbation, acute hypoxic respiratory failure, acute pneumonia, sepsis, and new onset A-Fib with RVR. In line with investigator's causality assessment, Sponsor assessed the events as not related to the study vaccine, due to biological and chronological implausibility. The subject's significant medical history included pneumonia, chronic obstructive pulmonary disease and asthma which are risk factors for the events including his elderly age. Of note, the subject sustained significant traumatic injuries to chest (4 broken ribs and contusions) due to a car accident 25 days earlier which may have further increased the subject's susceptibility to the events. Listedness was assessed using version.
