Effectiveness of the Pneumococcal Polysaccharide Vaccine in Military Recruits

Summary

The primary objective is to determine the clinical benefit of employing the 23-valent pneumococcal vaccine among US military trainees. Secondary objectives include: * determining the etiology of clinical pneumonia among U.S. military trainees; * comparing the serotype distribution of S. pneumoniae (Sp) isolates recovered from vaccinated and nonvaccinated trainees diagnosed with pneumonia; and * comparing days lost from training due to pneumonia or acute respiratory disease for vaccinated and nonvaccinated subjects.
