Fig. 8

Neutralization titers from mouse serum following immunization using WT VLPs-1 (cyan), WT VLPs-2 (blue), Gardasil 9 (brown), Cervarix (green), nona-type chVLP-1 (orange), and nona-type chVLP-2 (magenta). Titers were measured by PBNA covering the nine HPV types included in the vaccines (ac) and the 11 non-vaccine HPV types (df). Eighteen groups of mice were immunized with three dosages (13.5 μg, 1.35 μg, and 0.135 μg) of the six different vaccines at 0, 2, and 4 weeks. Serum samples were collected 2 weeks after the third immunization. N = 10 mice in each group. The neutralization titers were presented as mean ± SD. Statistical significance was assessed by two-way ANOVA: *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001. Non-neutralization samples were assigned a value of half of the limit of detection for visualization (the dotted line). Source data and exact p values are provided as a source data file.
