Figure 4

Comparison of frequencies of CD19+IL-10+ B (B10+) cells of second-generation hepatitis B vaccine non-responders and responders. Depicted are frequencies of B10+ cells of second-generation hepatitis B vaccine non-responders (NR, red circles) and second-generation hepatitis B vaccine responders (R, blue circles) before (day 0) and 7, and 28 days after vaccination with a third- (NR group) or second- (R group) generation hepatitis B vaccine, respectively. The boxes show the median and the 25th and 75th percentile. Whiskers indicate the highest and lowest values. Statistical analyses are based either on unpaired Mann-Whitney U tests for the analysis of the NR vs. the R group or on Friedman tests with post Wilcoxon signed rank testing for analysis of the impact of third- and second-generation hepatitis B vaccines within the NR or R group. ***p < 0.001; ****p < 0.0001.
