Table 3. Stimulation index (SI) of spleen cells.
| Group | n | SI(week 8) | P-value* |
|---|---|---|---|
| A1 | 3 | a 0.87 ± 0.23 | p < 0.001(A1-A2,B1,B2), p = 0.418(A1-C1), p = 0.820(A1-C2) |
| A2 | 3 | 4.52 ± 0.34 | p = 0.418(A2-B2), p < 0.001(A2- B1,C1,C2) |
| B1 | 3 | 3.42 ± 0.24 | p = 0.001(B1-B2), p < 0.001(B1-C1,C2) |
| B2 | 3 | 4.34 ± 0.32 | p < 0.001(B2-C1,C2) |

Note: a, mean ± SD *The groups are as given in the legend of Figure 1. By a one-way ANOVA,SI (A1, A2, B1, B2, C1, C2): f = 145.147, p < 0.001. Pairwise comparison was tested in groups (A1−C2). For example, “A1−A2” indicates that pairwise comparison was detected between the A1 control group and the A2 vaccine experimental group.
