Outcome Measures
Primary Outcomes (1)
Humoral immune response
The humoral immune response will be assessed at four different timepoints (Sample 1: prior to the fourth vaccine dose; sample 2: 1 months after the fourth vaccine dose; sample 3: 6 months after the fourth vaccine dose; sample 4: 12 months after the fourth vaccine dose or max. 4 weeks prior to the fifth vaccine dose, whichever comes first) through the measurement of the titers of Bioplex IgG antibody panel in study participant's blood samples.
12 months after start of study
Interventions
Four consecutive blood sampling throughout the overall follow-up period of 12 months.
