Lab test included on 28May2021 and 23Jun2021, includes Physical Exam: Basal cell. The action taken for adalimumab with respect to events was dose not changed. The outcome for event basal cell cancer on face and torso was not recovered and for all other events was recovered in May2021.  The reporter's causality for the events of basal cell cancer on face and torso, off label use and headache was not provided.

Information about lot/batch number cannot be obtained. ; Sender's Comments: Due to implausible temporal association, the event of basal cell carcinoma is assessed as unrelated to suspected vaccine bnt162b2. The patient has been on the medication for just few days, while it is known that the process of carcinogenesis takes months to years, moreover the patient had similar spot under her breast before vaccination. However,a possible contributory role of suspect product  bnt162b2 to the reported event nausea, headache, diarrhea, malaise and foggy feeling cannot be excluded. 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.
