Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate the homing potentials of circulating vaccine antigen-specific antibodysecreting cells towards gut mucosa (Dukoral, Vivotif), systemic immune system (Typherix, Prevenar, Prevenear13, Pneumovax, Flupar, Pandemrix, Vacxigrip) and cutaneous sites (Intanza) after immunisation with diffferent vaccines.;Secondary Objective: To evaluate the immunogenicity of the different vaccines against the same pathogen (Vivotif in comparison to Typherix®, Intanza® in comparison to Vacxigrip® and Flupar® in comparison to Pandemrix®, Pneumovax® in comparison to Prevenar13® or Prevenar®).;Primary end point(s): Measurement of specific IgA -, IgG- and IgM-secreting antibody cells specific to pathogen or antigen specific for the investigated vaccine in peripheral blood using ELISPOT.;Timepoint(s) of evaluation of this end point: The sample will be taken on day 7 after vaccination.
