Abstract The 23-valent pneumococcal vaccine is recommended for people aged 65 years and over, to prevent pneumonia, a leading cause of infectious morbidity in older people. This study assessed pneumococcal vaccination in people aged 65-74 years living in northern Israel who were eligible for the pneumococcal vaccine since introduction free of charge.This retrospective study used the database of Clalit Health Services, the largest health maintenance organization in Israel. We fitted a Cox regression model to assess associations of vaccine uptake with sociodemographic and clinical characteristics, and a Wilcoxon rank-sum test and Chi-square test to assess associations of vaccine uptake with the performance of other health-related activities. The analysis included 20,591 people. People aged 65-70 were more likely to take the vaccine than people aged 71-74 [HR=1.8; CI: 1.6-1.9]. Jews were more likely to take it than Arabs [HR=1.1; CI: 1.0-1.2], and men were more likely to take it than women [HR=1.1; CI: 1.0-1.2]. In women who took the vaccine, the rate of performance of mammography was higher (61.9 %±45.3 vs 50.3%±44.5, p Frequency of visits to family medicine clinics was negatively associated with vaccination. Uptake of the pneumococcal vaccine was associated with some parameters indicative of self-care but not with the level of exposure to the primary health care staff. After-hours health promotion activities by trained personnel may be an effective way to cope with the gap in performance.
