FIGURE 2.
SARS-CoV-2–specific humoral immunity elicited by the mRNA-1273 vaccine in SOT recipients: (A) proportion of patients with IgG antibodies targeting the SARS-CoV-2 S protein assessed by commercial ELISA at baseline, after the first vaccine dose vaccine, and at 2 wk after the completion of the vaccine series; (B) proportion with serum neutralizing activity against the S protein analyzed with an in-house hACE-2/spike antibody inhibition ELISA-based method at the same time points. Comparisons between repeated measures were performed with the Wilcoxon signed-rank test. hACE, human angiotensin-converting enzyme; IgG, immunoglobulin; S, SARS-CoV-2 spike glycoprotein; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2; SOT, solid organ transplantation.
