Immunization; Infection Clinical Trial
Official title:
Bioarray Compilation for the Serological Assessment of Immunity Against Vaccine-preventable Infections of Available Prophylaxis in Refugees and Immigrants
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.
The current massive inflow of refugees and migrants poses urgent necessity of i) rapid
identification of carriers of communicable diseases and ii) adjustment of protection against
vaccine-preventable infections to European standards. While universal vaccination is
supposed to ensure the intended degree of protection, targeted vaccination on the basis of
previous assessment of the immune status (seropositivity) was repeatedly shown to be a
cost-efficient alternative. Currently, the broad use of immune status assessment prior to
targeted vaccination is impeded by the necessity to apply separate seropositivity detection
assays for each individual condition. This drawback can be overcome by the introduction of a
comprehensive diagnostic tool permitting simultaneous assessment of seropositivity for
several vaccine-preventable infections.
The objective of the present study consists in compilation of an array of sera from
- subjects with known history of immunization against vaccine-preventable infections for
which vaccines are routinely available (measles, mumps, rubella, varicella, tetanus,
pertussis, poliomyelitis, diphtheria, meningococcal infection) and
- new migrants/refugees without reliable vaccination records and undefined immune status
to be subsequently used for the validation of a multi-pronged diagnostic tool for
seropositivity detection
