Corroboration of the antiviral effect of remdesivir against SARS-CoV-2 variants. Vero E6 cells were pretreated with remdesivir for 72 h and challenged with SARS-CoV-2. Infected cell supernatants at 48 h pi (MOI 0.02) were quantified by quantitative real time RT-PCR assay. The blue and red lines represent the CC₅₀ and IC₅₀, respectively; the blue squares represent cell viability (%) and the red circles represent SARS-CoV-2 infection inhibition (%). All experiments were performed in replicate
