Therapeutic measures were taken as a result of antiphospholipid syndrome. Clinical course: Immunosuppressive drugs used included IV dexamethasone, Hydroxychloroquin (HCQ), and prednisolone. Symptoms improved as clinical outcome.   No follow-up attempts are possible.  Follow-up (28Feb2024): This is a literature report for the following literature source(s). This is a follow-up report based on the receipt of the publication; the case has been updated to include additional information identified in the publication. Updated information: Reporter and literature information, RMH, Lab, Product details, dosage updated.; Sender's Comments: The event antiphospholipid syndrome is conservatively assessed as related to the suspect drug BNT162B2 based on close temporal association but consider also possible contributory effects from medical history of the patient and/or concomitant medications. The impact of this report on the benefit/risk profile of the Pfizer product 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.
