Effect of oral nirmatrelvir on Long COVID symptoms: a case series

Abstract As the SARS-CoV-2 pandemic continues to evolve, efforts to understand variability in COVID-19 recovery, as well as the impact of factors including viral variants, vaccine status, and COVID-19 treatment on the development and persistence of Long COVID symptoms have intensified. We report three cases that demonstrate that variability in the timing of nirmatrelvir therapy may be associated with different outcomes and underscores the need for systematic study of antiviral therapy for this disease condition.
