Figure 2.
Evaluation of Log10 antispike IgG (panel a), RBD IgG (panel b) at baseline (before vaccination), t1 (15 days after the first vaccination) and t2 (15 days after the second vaccination) and t3 (final blood sample from the participant at birth). Colored lines indicate the median. Dashed lines indicate detection limits. Differences in antibody levels between the different time points were determined by one-way analysis of variance and differences between specific time points were determined by post hoc paired t-tests and Wilcoxon signed rank tests for skewed data.

BAU, binding antibody unit; Ig, immunoglobulin; RBD, receptor binding domain.
