Bioarray Compilation for the Serological Assessment of Immunity Against Vaccine-preventable Infections of Available Prophylaxis in Refugees and Immigrants

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
