The prevention of pneumococcal infections deserves more attention because of aging populations and antimicrobial resistance.1 In this light, Nichol and colleagues2 reported important positive findings from a community-based, nonexperimental study on influenza and pneumonia immunization among those at highest risk: elderly patients with chronic pulmonary disease. In spite of this report, however, the issue of the incremental health and economic benefit of combined pneumococcal and influenza vaccination compared with influenza vaccination alone among a wider target group of high-risk patients remains unsolved.
