Large Community Outbreak of<i>Streptococcus pneumoniae</i>Serotype 5 Invasive Infection in an Impoverished, Urban Population

Abstract

A targeted vaccination campaign using polysaccharide pneumococcal vaccine appeared to help control this outbreak. In urban centers with high rates of illicit drug use, vaccination strategies for preventing invasive pneumococcal disease may need to be refined to include individuals who use crack cocaine.
