No further information is expected.; Sender's Comments: There is not a reasonable possibility that reported event of Tardive dyskinesia is  related to BNT162B2, this events are most likely intercurrent medical conditions of and concomitant medication  for this elderly patient with underlying Parkinsonism. However  a possible contributory role of the suspect vaccine to the reported events of Fall, dizziness and condition aggravated   a possible contributory role of the suspect vaccine.
