Herpes simplex virus retinitis following ChAdOx1 nCoV- 19 (Covishield) vaccination for SARS CoV 2: A case report.

To report a case of herpes simplex virus retinitis following ChadOx1 nCoV-19 (covishield) vaccination. A 29 year old immunocompetent male presented with unilateral disc edema with adjacent retinitis two days after receiving the first dose of ChAdOx1 nCoV-19 vaccination. Extensive investigations to rule out infective etiology were negative except for polymerase chain reaction (PCR) of the vitreous specimen which was positive for the herpes simplex virus. A diagnosis of herpes simplex (HSV) retinitis post covid vaccination was made. The patient responded well to oral antivirals and steroids. HSV retinitis is a rare complication following the COVID-19 vaccination. [ABSTRACT FROM AUTHOR]
