Sero-epidemiology of measles-specific IgG antibodies and predictive factors for low or missing titres in a German population-based cross-sectional study in children and adolescents (KiGGS)

► German Health Survey for Children provides representative data on measles antibodies. ► Prevalence of seronegativity in children aged 1-17 years was 10.0%. ► Age differences mainly due to differences in vaccination coverage. ► Waning and very young age at first dose associated with higher level of seronegativity. ► Immigrant children more often seronegative even if vaccination documented.
