Correlation between SARS-CoV-2 neutralizing antibody titers as measured by different VNA assays for all groups and time points except week 0 time point.
(A) Correlation between Leiden-0008 strain (B.1 lineage; LUMC) and Wuhan-Hu-1 (A lineage, Nexelis). rs = 0.90, P < 0.001. (B) Correlation between the Victoria/1/202 strain (A lineage; PHE) and Wuhan-Hu-1 (A lineage, Nexelis). rs = 0.91, P < 0.001. The dotted lines indicate the LLOD for each assay. Correlation coefficients between different neutralization assays were calculated using two-sided Spearman rank correlation.
