It was reported that the patient is perfectly healthy She does not drink or use any illicit drugs. She takes BCP to regulate her period and one month ago she started 5 mg/day Lexapro for test anxiety and COVID-induced depression.

On Fri 14May2021 shortly after lunch while working in her cubicle, she woke up with computer keyboard imprint on her face. Unwitnessed, no warning whatsoever. Sat pm after dinner while in backseat of car, she felt dizzy and within a minute or so she had brief LOC lasting less than 1 minute. Sun 16May2021 after breakfast while bathing, she passed out. Unwitnessed. Her phone was nearby so she was able to call me. After each episode, she consistently describes dark and blurred vision for 15 min. Then she feels fine. No obvious seizure activity although last night her boyfriend said her right arm was twitching. No incontinence.

No Neuro or cardiology consult (yet). Today her doctor is recommending she be admitted for observation, consults and further testing.  The patient has not received any other vaccinations prior 4 weeks and has no history of allergies. All tests done at the hospital came back normal. Daughter is currently in the hospital being discharged today 17May2021. She will wear a Holter monitor for 2 weeks to record any further events. Cardiology and neurology both conclude the adverse events were not cardio or neurological origin. Physician does not think it was seizures. She did not intend to report seizures-it was syncope. She does not have any further adverse events or history to report at this time beyond what she already reported.  The patient underwent lab tests and procedures which included blood test: normal, blood thyroid stimulating hormone: normal, electrocardiogram: normal, electroencephalogram: normal, investigation: normal, investigation: arrithymia, investigation: normal, physical examination: normal , pregnancy test: normal, urine analysis: normal on 13May2021, echocardiogram: normal, electrocardiogram: normal, full blood count: normal, investigation: normal, magnetic resonance imaging normal: normal on 14May2021. The outcome of the events was unknown.; Sender's Comments: As there is limited information in the case provided, the causal association between the events syncope, arrhythmia, dizziness, feeling hot, vision blurred, muscle twitching and the suspect drug BNT162B2 cannot be excluded.
