Open Access Abstract The effect of abatacept a selective T-cell eo-stimulation modulator on vaccination has not been previously investigated. In this open-label single-dose randomized parallel-group controlled study the effect of a single 750 mg infusion of abatacept on the antibody response to the intramuscular tetanus toxoid vaccine primarily a memory response to a T-cell-dependent peptide antigen and the intramuscular 23-valent pneumococcal vaccine a less T-cell-dependent response to a polysaccharide antigen was measured in 80 normal healthy volunteers. Subjects were uniformly randomized to receive one of four treatments Group A control group subjects received .
