Pneumococcal conjugate vaccines have proven highly effective in decreasing invasive disease and pneumonia in young children. However, there is considerable geographic variability in the impact of these vaccines on other disease endpoints and in other age groups. Investigation of the possible causes of this variability would greatly improve our understanding of pneumococcal pathophysiology and stimulate the effort to design more broadly effective vaccines.
