Vaccination Patterns and Determinants of Influenza and Pneumococcal Vaccines Among COPD Patients in Shanghai, China: A Comparative Analysis of Differing Funding Strategies.

ABSTRACT: Background: Preventing and reducing acute exacerbations is a key objective in chronic obstructive pulmonary disease (COPD) management. Therefore, vaccination against influenza and pneumococcal disease is particularly important for this population. Under self-funded vaccination policies, the coverage rates for both vaccines among COPD patients in China are critically low. Since 2013, Shanghai has implemented a program providing one free dose of the 23-valent pneumococcal polysaccharide vaccine (PPV23) to residents aged 60 and above, whereas influenza vaccination remains self-funded. Few studies have compared influenza and pneumococcal vaccination coverage among COPD patients in China under these distinct funding strategies. Methods: This study used a stratified cluster samplin
