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.
