Activation of B cells, T cells and NK cells
In addition to the virus-specific binding IgG antibody responses and nAbs we, we expanded the analyses in exploratory studies to investigate specific cellular responses following vaccination of the different cohorts. Freshly isolated PBMCs from each time-point were used to assess the effects of concomitant vaccinations on lymphocyte activation. Co-expression of CD38 and Ki67 in B cells, CD4
