The occurrence of additional non-serious events is detailed below.     Concurrent medical conditions included Blood pressure (high blood pressure).   On 04-Jan-2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (Intramuscular) 1 dosage form.

On 30-Jan-2021, the patient experienced MOBILITY DECREASED (didn't want to do anything), FATIGUE (wiped out), CHILLS (chills), PYREXIA (fever) and HEADACHE (headache). On 02-Feb-2021, the patient experienced RETINAL ARTERY OCCLUSION (eye stroke) (seriousness criteria hospitalization and medically significant). 02-Feb-2021, the patient experienced BLINDNESS (lost vision in my left eye) (seriousness criteria hospitalization and medically significant). The patient was hospitalized from 02-Feb-2021 to 03-Feb-2021 due to BLINDNESS.

Company comment: This case concerns a 64 year-old female patient with a history of high blood pressure who experienced the unexpected serious event of retinal artery occlusion and blindness. The events occurred approximately 3 days after the second dose of mRNA-1273. The rechallenge was unknown as no additional dosing will be administered. The medical history of high blood pressure remains a confounder. The benefit-risk relationship of mRNA-1273 is not affected by this report.
