NCT03107312

Brief Summary

Recent observations in Germany revealed above-average high proportions of refugees affected by infectious diseases of public health significance. Scrutiny of the vaccination status showed sizeable presence of seronegative subjects, with conspicuously higher prevalence among children and adolescents, thus indicating urgent necessity of i) rapid identification of carriers of vaccine-preventable diseases and ii) adjustment of protection against such infections to European Standards. Rapid immune status check needs comprehensive diagnostic tool permitting simultaneous assessment of seropositivity. Validation of such tools requires comparisons of the immune status of subjects with known vaccination history with that of migrants with incomplete or missing health and vaccination records.
