SARS-CoV-2 is a new pandemic virus for which Remdesivir is the only antiviral available. We report the occurrence of a mutation in the RdRP (D484Y) following failure of remdesivir in a 76-year-old woman with a post-rituximab B-cell immunodeficiency and persistent SARS-CoV-2 viremia. Cure was reached after supplementation with convalescent plasma.
