Abstract:
Objective:To investigate the vaccination rate of 23-valent pneumococcal polysaccharide vaccine (PPV23), identify determinants of vaccination willingness, and analyze barriers to vaccination among community-dwelling elderly in Xinzhuang Town of Shanghai Minhang District.Methods:This cross-sectional study was conducted in Xinzhuang Town of Shanghai Minhang District from November to December 2024. An online questionnaire was distributed via WeChat groups of neighborhood committees to community-dwelling elderly (aged≥60 years) using a convenience sampling method. The questionnaire covered basic demographic information, health status, knowledge and awareness about pneumonia and PPV23, attitudes toward PPV23 vaccination, and vaccination behavior. The χ2 test and multivariate logistic regression analysis were employed to identify factors influencing the PPV23 vaccination rate and willingness to vaccination among the elderly. Results:A total of 667 questionnaires were collected and 612 were valid (91.8%). Among 612 responders there were 223 males (36.44%) and 389 females (63.56%), and 304 (49.67%) aged 70-79 years. In all respondents, 185 (30.23%) had previously received PPV23, while 427 (69.77%) had not. Reasons for non-vaccination included unawareness of vaccine necessity (31.85%, 136/427), self-perceived good health (31.15%, 133/427), concerns about adverse reactions (21.08%, 90/427), and lack of physician recommendation (14.52%, 62/427). In all participants, 65.85%(403/612)expressed willingness for vaccination and 34.15%(209/612) did not have willingness. Factors significantly influencing vaccination willingness included negative perception of vaccine efficacy ( OR=2.750, 95% CI:1.077-7.023), concerns about adverse reactions ( OR=2.568, 95% CI:1.258-5.242), low awareness of pneumonia and PPV23 vaccine ( OR=11.608, 95% CI:4.177-32.258), perceived vaccination inconvenience ( OR=0.457, 95% CI:0.248-0.844), and belief in good health negating need ( OR=2.658, 95% CI:1.361-5.190) (all P<0.05). Conclusions:Suboptimal PPV23 vaccination rates and low willingness among community-dwelling elderly in Shanghai Xinzhuang Town are driven by knowledge gaps and perceptual barriers. Targeted interventions should prioritize physician engagement, accessible vaccination services, and public education addressing safety and efficacy concerns.
