Effect of the 7‐Valent Pneumococcal Conjugate Vaccine on Nasopharyngeal Colonization by<i>Streptococcus pneumoniae</i>in the First 2 Years of Life

The reduction of VT-SP colonization and replacement by NVT SP after the booster dose of vaccine suggests the possibility that widespread vaccination will result in replacement of pneumococci mainly by antibiotic-susceptible NVT SP.
