The patient underwent lab tests and procedures which included alanine aminotransferase: 93 (unit unspecified) on 10Mar2021, alanine aminotransferase: 86 (unit unspecified) on 11Mar2021, aspartate aminotransferase: 206 (unit unspecified) on 09Mar2021, aspartate aminotransferase: 118 (unit unspecified) on 11Mar2021, blood alkaline phosphatase: 137 (unit unspecified) on 09Mar2021, blood creatinine: normal on an unspecified date, blood electrolytes: largely normal on an unspecified date, blood lactate dehydrogenase: 2019 (unit unspecified) on 10Mar2021, blood lactate dehydrogenase: 1728 (unit unspecified) on 11Mar2021, haemoglobin: 11.9 (unit unspecified) on 06Mar2021, haemoglobin: 8.3 (unit unspecified) on 11Mar2021, haemoglobin urine: 3+ (unit unspecified) on an unspecified date, adamts-13: with pending results on an unspecified date, platelet count: 80 (unit unspecified) on 06Mar2021, platelet count: 59 (unit unspecified) on 11Mar2021 and WBC: Normal on an unspecified date. Therapeutic measures were taken as a result of the events Coombs negative hemolytic anemia, Within minutes of 2nd dose of vaccine, pt had urination of dark brown urine, Migraine, Fever, Nausea, Diarrhea, Her Hgb has been dropping from 11.9 06Mar down to 8.3 11Mar, She had a max AST 206 09Mar down to 118 11Mar and ALT 93 10Mar now 86 11Mar. Outcome of all the events  was not recovered.; Sender's Comments: Based on available information, a possible contributory role of the subject product, BNT162B2 vaccine, cannot be excluded for the reported event of  Coombs negative hemolytic anemia and other events  due to temporal relationship. However, the reported events may possibly represent intercurrent medical conditions in this patient.  There is limited information provided in this report.  Additional information is needed to better assess the case, including complete medical history, diagnostics, counteractive treatment measures and concomitant medications. This case will be reassessed once additional information is available.  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.
