Dynamics of the anti-SARS-CoV-2 antibody response after vaccination with two doses of the BNT162b2 vaccine. The plot shows the dynamics of the mean antibody titer at the five sample-collection time-points. The error bars indicate the standard deviation. Alinity RBD-IgG; antibody titer for the receptor-binding domain of SARS-CoV-2 was measured using SARS-CoV-2 IgG II Quant reagents and Alinity System (Abbott Laboratories, Illinois, USA), HISCL S-IgG: antibody titer for anti-SARS-CoV-2 spike protein measured using HISCL SARS-CoV-2 S-IgG reagents and an HISCL Analyzer (Sysmex Corporation, Kobe, Japan); STACIA Neut-Ab: neutralizing ability for SARS-CoV-2 using STACIA SARS-CoV-2 Neutralization Antibody Test reagents (MBL Corporation, Nagoya, Japan), and a STACIA Analyzer (LSI Medience Corporation, Tokyo, Japan). Paired t-tests were used to calculate the p values (*** p < 0.001). The Y-axes are on a logarithmic scale.
