Figure 5. Homing potentials of Salmonella Typhi-specific plasmablasts in the two vaccination groups.

The expression of α₄β₇, L-selectin and CLA on Salmonella Typhi-specific plasmablasts in the peripheral blood of volunteers seven days after vaccination with the Vi or the Ty21a vaccine. The bars indicate the arithmetic means +95%CI of percentages of HR-positive ASC among all pathogen-specific ASC (IgA+IgG+IgM). The HRs and the numbers of volunteers from whom the data were pooled are indicated under the data bars. The data on HR expressions on S. Typhi-specific plasmablasts in Ty21a-vaccinated volunteers has been reported earlier [32]. The statistical comparisons (Wilcoxon signed rank test) between the strains in the two vaccination groups are indicated with asterisks (***p<0,001; **0.001<p<0.01, *p<0,05).
