Humoral immune response with SmT1-based vaccine formulations in hamsters. Syrian Golden hamsters (n = 6/group) were immunized i.m. with 3 µg of SmT1 alone or with SLA, CpG or SLA + CpG on Days 0 ± 21. Serum was collected on Days 21 (A) and 34 (B) and analyzed by ELISA to determine the antibody titers. Grouped data is presented as geometric mean + 95% confidence interval. Serum from Day 34 was also analyzed at a final serum dilution of 1:25 (C) and 1:75 (D) by cell-based surrogate neutralization assay. Grouped data is presented as mean + standard error of mean. Statistical significance of differences for the adjuvanted groups vs. the antigen alone control group is shown: **p < 0.01, ***p < 0.001 and ****p < 0.0001 by one-way ANOVA followed by Tukey's multiple comparisons test.
