Therapeutic measures were taken as a result of pancreatitis acute.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.; Sender's Comments: Based on the information available  a possible contributory role of the suspect BNT162B2  cannot be excluded for the reported events of Acute Pancreatitis.
