Nonetheless, concentrations of antibodies to three conserved pneumococcal antigens correlated with protection against colonization. Concentrations of antibodies to conserved pneumococcal antigens may be correlates of protection without being effectors of protection.en-USJournal Article2016-05-1010.1128/IAI.73.10.7043-7046.2005
