The occurrence of additional non-serious events is detailed below.     Previously administered products included for Product used for unknown indication: Moderna covid-19 vaccine (Dose 1, Lot no: 011L20A) on 29-Dec-2020 and Flu shot; for Drug use for unknown indication: Moderna covid-19 vaccine (Dose 2, lot no: 011L20A) on 27-Jan-2021 and Moderna covid-19 vaccine (Booster 1). Past adverse reactions to the above products included No adverse event with Flu shot and Moderna covid-19 vaccine; and No adverse reaction with Moderna covid-19 vaccine and Moderna covid-19 vaccine.

On an unknown date, the patient experienced AUTONOMIC NEUROPATHY (idiopathic peripheral neuropathy in feet) (seriousness criterion medically significant), CONDITION AGGRAVATED (idiopathic peripheral neuropathy in feet has gotten worse), CONFUSIONAL STATE (intermittent mild confusion), DISTURBANCE IN ATTENTION (periods of loss of concentration), FEELING ABNORMAL (foggy) and DIZZINESS (intermittent lightheadedness). At the time of the report, AUTONOMIC NEUROPATHY (idiopathic peripheral neuropathy in feet), CONDITION AGGRAVATED (idiopathic peripheral neuropathy in feet has gotten worse), CONFUSIONAL STATE (intermittent mild confusion), DISTURBANCE IN ATTENTION (periods of loss of concentration), FEELING ABNORMAL (foggy) and DIZZINESS (intermittent lightheadedness) had not resolved.
