Capsular Serotype–Specific Attack Rates and Duration of Carriage of<i>Streptococcus</i><i>pneumoniae</i>in a Population of Children

Abstract

The capsular serotype is a major determinant of both pneumococcal duration of carriage and attack rate. Published invasive odds ratios are a reliable and practical method of determining capsular serotype invasiveness and will be valuable for investigating and characterizing emerging capsular serotypes in the context of conjugate vaccination.
