Clinical narrative: Transient global amnesia attack/  Disoriented with no short term memory/I have no memory of events; This spontaneous case was reported by a patient and describes the occurrence of TRANSIENT GLOBAL AMNESIA (Transient global amnesia attack/  Disoriented with no short term memory/I have no memory of events) in a female patient of an unknown age who received mRNA-1273 BIVALENT .222 (MODERNA COVID-19 VACCINE, BIVALENT (ORIGINAL AND OMICRON BA.4/BA.5)) (batch no. A57145B) for COVID-19 prophylaxis.     No Medical History information was reported.    On 13-Sep-2022, the patient received dose of mRNA-1273 BIVALENT .222 (MODERNA COVID-19 VACCINE, BIVALENT (ORIGINAL AND OMICRON BA.4/BA.5)) (unknown route) 1 dosage form. On 14-Sep-2022,  after starting mRNA-1273 BIVALENT .222 (MODERNA COVID-19 VACCINE, BIVALENT (ORIGINAL AND OMICRON BA.4/BA.5)), the patient experienced TRANSIENT GLOBAL AMNESIA (Transient global amnesia attack/  Disoriented with no short term memory/I have no memory of events) (seriousness criterion hospitalization). The patient was hospitalized from 14-Sep-2022 to 15-Sep-2022 due to TRANSIENT GLOBAL AMNESIA. At the time of the report, TRANSIENT GLOBAL AMNESIA (Transient global amnesia attack/  Disoriented with no short term memory/I have no memory of events) had resolved.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On 14-Sep-2022, Blood test: came back normal. On 14-Sep-2022, Computerised tomogram: came back normal.. On 14-Sep-2022, Electroencephalogram: came back normal. On 14-Sep-2022, Lumbar puncture: came back normal. On 14-Sep-2022, Magnetic resonance imaging: came back normal.     The action taken with mRNA-1273 BIVALENT .222 (MODERNA COVID-19 VACCINE, BIVALENT (ORIGINAL AND OMICRON BA.4/BA.5)) (Unknown) was unknown.   For mRNA-1273 BIVALENT .222 (MODERNA COVID-19 VACCINE, BIVALENT (ORIGINAL AND OMICRON BA.4/BA.5)) (Unknown), the reporter did not provide any causality assessments.   Concomitant medications were not reported.  Patient was hard of hearing so don't talk on the phone. Patient's husband rushed to the ER. They had me spend the night at the hospital for observation. Patient had had no memory of events from 6 am until about noon that day. Doctor believed that it was a transient global amnesia attack due to the vaccine.

Company comment: This is a spontaneous case concerning a female patient of unknown age with no reported medical and vaccination history. The patient experienced the unexpected serious (hospitalization) event of transient global amnesia. The event occurred the next day after the unknown dose number of mRNA-1273.222 vaccine administration. Allegedly the event was described as, patient received mRNA-1273.222 and woke up the next day disoriented with no short-term memory. The patient was brought to the emergency department. The patient underwent computerised tomogram, electroencephalogram, lumbar puncture, unspecified magnetic resonance imaging with and without contrast, and lots of unspecified blood works. It was reported that the test results came back normal. The patient was admitted overnight for observation. It was reported that the patient had no memory of the events from 6 in the morning until about noon that day. It was reported that the neurologist on staff believes it was transient global amnesia attack. The benefit-risk relationship of mRNA-1273.222 vaccine is not affected by this report.; Sender's Comments: This is a spontaneous case concerning a female patient of unknown age with no reported medical and vaccination history.
