Therapeutic measures were taken as a result of retinal white dots syndrome.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.; Sender's Comments: As there is limited information in the case provided, the causal association between the reported event: "Retinal white dots syndrome" and the suspect drug BNT162B2 cannot be excluded. The case will be reassessed once new information is available.
