Company comment: This is a spontaneous case concerning a 57-year-old female patient with medical history of allergies (Oak trees, Dust, Pollen, Flowers), who experienced the unexpected, serious (hospitalization and medically significant) adverse event of special interest of COVID-19 pneumonia and the unexpected, serious (hospitalization) event of Hypersensitivity. 3 days after receiving the first dose of mRNA-1273 vaccine, the patient had difficulty breathing complications. 4 days after the onset of difficulty breathing the patient was hospitalized due to COVID-19 pneumonia (SARS-CoV-2 test positive and X-ray showed pneumonia) and allergies that flares up. She was treated with COVID antibodies and was hospitalized for 13 days. The event COVID-19 pneumonia had resolved within the same year and the outcome of the event Hypersensitivity was unknown at the time of the report. Medical history of allergies remains a risk factor for the event Hypersensitivity. The benefit-risk relationship of mRNA-1273 is not affected by this report.; Sender's Comments: This is a spontaneous case concerning a 57-year-old female patient with medical history of allergies (Oak trees, Dust, Pollen, Flowers), who experienced the unexpected, serious (hospitalization and medically significant) adverse event of special interest of COVID-19 pneumonia and the unexpected, serious (hospitalization) event of Hypersensitivity. 3 days after receiving the first dose of mRNA-1273 vaccine, the patient had difficulty breathing complications. 4 days after the onset of difficulty breathing the patient was hospitalized due to COVID-19 pneumonia (SARS-CoV-2 test positive and X-ray showed pneumonia) and allergies that flares up.
