Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To study opsonizing IgG after vaccination with a conjugated pneumococcal vaccine given to patients with IgG-deficiency.;Secondary Objective: To study cellular immune responses after vaccination with a conjugated pneumococcal vaccine given to patients with IgG-deficiency.;Primary end point(s): Opsonophagocytic activity of pre- and postvaccination titers, respectively.;Timepoint(s) of evaluation of this end point: We will compare titer after 4 weeks with baseline, but will also evaluate titers after 1 and 2 weeks post vaccination. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Cellular immune-responses against penumococcal vaccine strains.;Timepoint(s) of evaluation of this end point: The cellular immune response will be evaluated at time=0, 1 week, 2 weeks and 4 weeks, where the secondary endpoint is the difference between baseline and 4 weeks. | — |
