Figure 4.

Time-dependent trajectories of env antibody titre, env antibody avidity and neutralizing antibody against vaccine strain in three diversity-dependent inoculated groups. (A–C) The time-dependent titre of env Abs, env Abs avidity and nAbs against vaccine strain are shown cross three inoculated groups. (D–F) The time-dependent slopes of the env Abs titre, env Abs avidity and the titre of nAbs were compared between three groups based on supposed linear regression. The steepest slope by time was seen in the group inoculated with EIAV_HD.
