Tetanus- and diphtheria-specific Ab concentrations measured by ELISA. Tetanus- a and diphtheria- b specific Ab concentrations of young and elderly adults are shown as geometric mean concentrations (GMCs) ± 95 % confidence interval. Ab concentrations of young and old donors were compared before (day 0_2010), 4 weeks after (day 28_2010) as well as 5 years after (2015) a tetanus and diphtheria booster shot. Wilcoxon-signed rank test was applied for comparisons within the age groups (paired data) and the Wilcoxon rank-sum test was applied for comparisons among the age groups (unpaired data). * p = 0.0266 (young vs. old in 2015) ** p = 0.0052 (young pre-vaccination 2010 vs. 2015)
