On 16-Jan-2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On 16-Feb-2021, received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to 1 dosage form. On an unknown date, the patient started APIXABAN (ELIQUIS) (unknown route) 1 dosage form. In February 2021, the patient experienced FALL (Collapsed at home after 2nd shot) (seriousness criteria hospitalization and medically significant), HYPOXIA (O2 level fell into 70's at home after 2nd shot) (seriousness criteria hospitalization and medically significant) and THROMBOSIS (Diagnosed with multiple blood clots in legs, lungs, and brain after 2nd shot/ Thrombosis after 2nd shot) (seriousness criteria hospitalization and medically significant). On an unknown date, the patient experienced PNEUMONIA (Pneumonia attack after 2nd shot) (seriousness criteria hospitalization and medically significant) and ADVERSE DRUG REACTION (Terrible reaction to Eliquis). The patient was hospitalized from sometime in February 2021 to sometime in May 2021 due to HYPOXIA and THROMBOSIS, and then on sometime in February 2021 due to FALL. In May 2021, ADVERSE DRUG REACTION (Terrible reaction to Eliquis) had resolved. At the time of the report, FALL (Collapsed at home after 2nd shot), HYPOXIA (O2 level fell into 70's at home after 2nd shot), PNEUMONIA (Pneumonia attack after 2nd shot) and THROMBOSIS (Diagnosed with multiple blood clots in legs, lungs, and brain after 2nd shot/ Thrombosis after 2nd shot) had resolved.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): In February 2021, Oxygen saturation: low (Low) O2 level fell into 70s.     For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments.   Concomitant drug include probiotics.

Company Comment: This case concerns an 84 year-old female patient with no reported medical history, who experienced the unexpected serious events of Fall, Hypoxia, Thrombosis (AESI), and Pneumonia. The events occurred an unknown number of days after the second dose of mRNA-1273 vaccine. Although the medical history is not reported, the patient reports multiple concomitant medications commonly used to treat chronic comorbidities that may have contributed to the events and the seriousness. The benefit-risk relationship of mRNA-1273 vaccine is not affected by this report.
