Fig. 2

Decrease of diphtheria-specific antibody concentrations over 5 years. Depicted is the fold-reduction of diphtheria-specific antibodies from 4 weeks after the first vaccination until immediately before the second vaccination (5 years). Boxes show 25th and 75th percentiles, the median value is indicated. Whiskers depict 5th and 95th percentiles. The differences between CMV-negative and CMV-positive groups was calculated using Mann-Whitney U test. *p < 0.05
