The events "sars-cov-2 test: (27jan2022) positive", "tachycardia", "blood pressure fluctuations", "shortness of breath", "vertigo", "tremors", "tinnitus and severe insomnia", "condition was disruptive enough to require accommodations allowing me to work from home", "internal vibrations", "tingling/burning in fingers/hands", "weakness in arms or legs", "chest discomfort", "pressure at back of head/neck" and "shoulder, neck/ tingling/burning" required physician office visit and emergency room visit. The patient underwent the following laboratory tests and procedures: SARS-CoV-2 antibody test: (17Mar2022) Positive, notes: Blood test; SARS-CoV-2 test: (27Jan2022) Positive, notes: Nasal Swab. Therapeutic measures were taken as a result of tachycardia, blood pressure abnormal, dyspnoea, vertigo, tremor, tinnitus, insomnia, disability, joint vibration, burning sensation, paraesthesia, asthenia, chest discomfort, head discomfort, burning sensation, paraesthesia. Clinical information: After receiving the Pfizer booster, I experienced tachycardia, blood pressure fluctuations, shortness of breath, vertigo and tremors. This continued for four weeks at which point the tremors subsided and were replaced with internal vibrations, vertigo, tinnitus and severe insomnia. Four months later, I continue to experience these symptoms, along with occasional other symptoms like tingling/burning in fingers/hands, shoulder, neck and/or under scalp, pressure at back of head/neck, weakness in arms or legs, and chest discomfort. Condition was disruptive enough to require accommodations allowing me to work from home. No covid prior vaccination. Patient tested covid positive post vaccination.; Sender's Comments: Based on the available information in the case, the causal association between the reported events and the suspect drug BNT162B2 cannot be excluded.  The impact of this report on the benefit-risk profile of the Pfizer product and on the conduct of the study is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events. Any safety concern identified as part of this review, as well as any appropriate action in response, will be promptly notified to regulatory authorities, Ethics Committees, and Investigators, as appropriate.
