Neutralization of the autologous SARS-CoV-2 strain (Wuhan-Hu-1) in mice immunized with the vaccines indicated below the x axis at different time points. (A) Day 42 (14 d after the first vaccine boost). (B) Day 56 (28 d after the first vaccine boost). (C) Day 127 (14 d after the second vaccine boost). (D) Day 222 (16 wk after the second vaccine boost). The median titer is indicated by a horizontal line in each box. No statistical differences were seen by either parametric or nonparametric t tests presumably due to the wide data dispersion.
