He had received his Pfizer COVID-19 booster injection on last Tuesday.  On the following day, he began to notice shortness of breath and cough.  He subsequently developed fevers, generalized weakness with myalgias, etc.  He became more short of breath today and presented to the ER for evaluation.  Upon arrival, his oxygen saturation was 90% on room air.  ABG revealed hypoxemia with PO2 of 53.  His SpO2 improved with 2 L supplemental oxygen.  Imaging was consistent with viral pneumonia.  With concern for COVID-19 and hypoxemia with multiple comorbid conditions, he was admitted to the COVID step-down unit for further workup and management.   As mentioned, the patient is fully vaccinated COVID and has received his booster.  However, he is immunosuppressed with azathioprine and chronic prednisone.
