Pneumococcal polysaccharide vaccine does not confer protection against noninvasive pneumonia. The study compares the homing profiles of Pnc-specific plasmablasts in 15 patients with pneumonia and in 15 volunteers receiving Pnc polysaccharide vaccine (PPV) and 12 volunteers receiving Pnc conjugate vaccine (PCV)
Pneumococcal polysaccharide vaccine does not confer protection against noninvasive pneumonia. The study aims to compare lymphocyte homing in pneumonia and in those receiving Pnc polysaccharide vaccine (PPV) or Pnc conjugate vaccine (PCV)
