Why this research matters now
Findings highlight an intention-behavior gap and point to community-based service strengthening, life-course immunization promotion, policy communication, and expanded subsidies as relevant strategies for sustaining vaccination uptake in older adults.
Structured evidence summary
Research question
The study examined post-pandemic willingness, actual uptake, and determinants of seasonal influenza and pneumococcal vaccination among older adults in Shenzhen, China.
Study design
A cross-sectional survey conducted from January to May 2024, using descriptive statistics, chi-square tests, and multivariable logistic regression to identify predictors of willingness and uptake.
Population and setting
Adults aged 60 years and older (n=1917) residing in Shenzhen, China, surveyed in a post-pandemic context.
Main findings
Reported willingness to receive seasonal influenza (77.4%) and pneumococcal (73.4%) vaccines was high, but actual uptake was notably lower (55.1% and 29.2%, respectively), with over 70% attributing increased willingness to the COVID-19 pandemic. Key predictors included prior vaccination, concern about the illness, awareness of free vaccination policy, awareness of life-course vaccination, having a family doctor, frequent health check-ups, and, for pneumococcal vaccine, higher household income. Willingness-to-pay remained low, and healthcare providers, community channels, and traditional media were main information sources.
Public-health relevance
Findings highlight an intention-behavior gap and point to community-based service strengthening, life-course immunization promotion, policy communication, and expanded subsidies as relevant strategies for sustaining vaccination uptake in older adults.
Important limitations
The summary is limited to the supplied single-article abstract and bibliographic metadata; explicit limitations are not detailed in the abstract, and the original paper is required for decision-grade interpretation.
GIDS interpretation
The article addresses discoverability and context factors relevant to adult vaccination behavior in a post-pandemic urban Chinese setting; no connection to a live surveillance signal is made.
Related GIDS surveillance
Literature context does not validate, explain, or change a surveillance signal. Exact and contextual relationships are shown separately.
