The occurrence of additional non-serious events is detailed below.     The patient's past medical history included Bypass surgery (had bypass 25 years ago.). Concurrent medical conditions included Cardiac disorder.   In April 2021, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to 1 dosage form. On an unknown date, the patient received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. On an unknown date, the patient experienced POOR QUALITY SLEEP (he is not sleeping well), FEELING ABNORMAL (He wakes up as if he had a hangover), CLUMSINESS (getting clumsy), MEMORY IMPAIRMENT (he is forgetting things/his mind is not working correctly), FALL (he has fallen 4 times in the last month), MOBILITY DECREASED (he cannot walk 100ft that he has to rest), WEIGHT INCREASED (Before he was 179lb and now he is 191lb), HYPOTONIA (no muscle tone) and FATIGUE (he is tired all the time). At the time of the report, POOR QUALITY SLEEP (he is not sleeping well), FEELING ABNORMAL (He wakes up as if he had a hangover), CLUMSINESS (getting clumsy), MEMORY IMPAIRMENT (he is forgetting things/his mind is not working correctly), FALL (he has fallen 4 times in the last month), MOBILITY DECREASED (he cannot walk 100ft that he has to rest), WEIGHT INCREASED (Before he was 179lb and now he is 191lb), HYPOTONIA (no muscle tone) and FATIGUE (he is tired all the time) had not resolved.

The events occurred  on unknown date after second dose of mRNA 1273 vaccine. The patient felt that his mind was not working correctly, he is forgetful, clumsy and has fallen several times. There were no treatment information given. The rechallenge is not applicable as events are still ongoing. The patient's age remains a confounder to events fall, and memory impairment.
