Comparison between neutralization assays. Selected serum samples (N = 19) were assayed using neutralization assays based on infectious SARS-CoV-2 (VNT) and on lentiviral vector pseudotyped with Spike (LV-Luc). (a) Correlation between the ID50 (log10) values obtained from the two assays. Dots correspond to individual measurements; the black line represents the regression line. (b) Comparison of ID50 (log10) values obtained using the two assays. A Wilcoxon matched-pairs signed rank test was used to compare the assays. The black line indicates the median ID50, the dotted line indicates the assay cut off (minimum serum dilution tested: 1:20 dilution).
