List of Figures
Figure 1. Heatmap representing antibody levels before and after
the BNT162b2 booster shot in previous recipients of CoronaVac. A) S IgM
levels. B) N IgG levels. C) S IgG levels. Antibody responses were
evaluated before the third dose (B/3D), 30 (30d/3D), 60 (60d/3D), 90
(90d/3D) and 180 (180d/3D) days after the third dose, in 64
participants. The deeper red color represents the higher relative
intensity, the deeper blue color the lower relative intensity, and the
intermediary intensity is a white color. In phase 180d/3D, the deeper
gray corresponds to the absence of antibody data from two participants.
Figure 2. Comparison of antibody response before and after the
BNT162b2 booster shot in previous recipients of CoronaVac, by PCR
positivity status. A) S IgM levels. B) N IgG levels. C) S IgG levels.
Antibody responses were evaluated before the third dose (B/3D), 30
(30d/3D), 60 (60d/3D), 90 (90d/3D) and 180 (180d/3D) days after the
third dose. Horizontal black lines in the boxplots represent median
levels values and error bars min and max values; the horizontal red
dotted lines indicate the cutoff value of the assays. Statistical
analysis was performed using the Kruskal–Wallis test with subsequent
Dunn’s multiple testing correction. N, nucleocapsid protein; S, spike
protein; S/C, signal- to- cutoff- ratio.
