For mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular), the reporter considered STILL'S DISEASE (Adult-onset Still's disease), ACUTE RESPIRATORY FAILURE (Acute hypoxic respiratory failure) and PNEUMONIA (suspected community acquired pneumonia) to be possibly related.    Patient developed a sore throat, intermittent headache, and fever at 5 days after the second dose of the vaccine, approximately one month after the first dose. Over the next few days, she continued to have persistent daily fevers of up to 40°C despite consistent use of acetaminophen and nonsteroidal anti-inflammatory drugs. She subsequently developed severely debilitating myalgias,  arthralgias, and pleurisy that ultimately prompted her to seek medical attention. She was treated empirically with antibiotics for suspected community acquired  pneumonia and her hypoxia resolved within 24 hrs. On the second day of admission she  developed an evanescent salmon-colored rash over the upper back, dorsal aspect of the hands, and bilateral thighs occurring with fevers. Serological testing including rheumatoid factor, cyclic citrullinated peptide antibody IgG, and antinuclear antibody was negative. After a thorough unremarkable infectious and malignancy  work-up was completed, the patient was diagnosed with AOSD. At the time of diagnosis, according to the Yamaguchi classification criteria of AOSD, the patient met three of four major criteria (fever, typical rash, leukocytosis) and four of five minor criteria (sore throat, lymphadenopathy, abnormal liver function tests, and negative rheumatoid factor and antinuclear antibody).The patient started treatment with prednisone 60 mg daily (1 mg/kg per day) with immediate resolution of her fevers and skin rash, and rapid improvement of her arthralgias and myalgias over the subsequent 3 days. There was a worsening thrombocytosis for the first few  days after treatment initiation, which was deemed to be reactive and eventually improved with the rest of the inflammatory markers.
