Dynamics of the anti-spike SARS-CoV-2 antibody response after full vaccination with two doses of the BNT162b2 vaccine. Anti-spike SARS-CoV-2 antibody levels were measured in blood samples at 6 W, 3 M, 4 M, and 7 M. Box plots show the median and quartiles. The Friedman test was used to calculate the P values (****P < 0.0001).
