The specific aim is to evaluate the impact of PCV13 as administered in the pediatric primary care clinic at Boston medical center on the serotype specific carriage of Streptococcus pneumoniae in children < 5 and their parents.

Specifically the investigators will measure the decline in vaccine serotypes, the proportion of children receiving vaccine required to achieve 50% reduction in serotype specific carriage and the correlation between immunogenicity of the specific serotypes and decline in carriage.
