PPSV23 vs PCV13
PPSV23: Contains 23 polysaccharides. Induces a relatively T-cell-independent B-cell-response that is less affective in young children and the elderly.
PCV13: contains 13 polysaccharides that have been covalently attached to inactivated diphtheria toxin protein. Induces a T-cell-dependent B-cell response resulting in improved immunogenicity due to the formation of higher affinity antibodies and memory cells
