Therapeutic measures were taken as a result of subacute inflammatory demyelinating polyneuropathy.; Sender's Comments: Based on the current available information and the plausible drug-event association, a possible contributory role of the suspect product BNT162B2 to the development of the Subacute inflammatory demyelinating polyneuropathy cannot be fully excluded.
