Outline
To describe the trends in influenza vaccination coverage among children under five years old in Zhangjiagang from 2021 to 2024, and to explore the key determinants of parental vaccine acceptance using the Behavioural and Social Drivers (BeSD) framework, in order to provide scientific evidence for optimizing immunization strategies.
Data were obtained by integrating influenza vaccination records from the Jiangsu Provincial Immunization Information System and population statistics from the Zhangjiagang Statistical Yearbook. A BeSD-based questionnaire survey was conducted to assess the impact of parental cognitive attitudes, social support, and service accessibility. Descriptive statistics and logistic regression analyses were used to examine the associations between these factors and children’s influenza vaccination behavior.
Coverage increased from 8.12% in 2021 to 12.32% in 2024, remaining low. A total of 900 questionnaires were distributed, and 796 valid responses were included in the analysis. Multivariable analysis showed that older age (36-<60 months, OR=2.72), prior non-EPI vaccination (OR=2.17), school-based information (OR=1.90), vaccination intention (OR=7.21), healthcare provider recommendation (OR=2.81), and prior parental vaccination experience (OR=16.37) significantly promoted uptake. Living in non-urban areas (OR=0.60) and grandparent caregivers (OR=0.60) were barriers.
Vaccination coverage remains suboptimal. It is recommended to strengthen the health education capacity of medical staff and optimize the convenience of vaccination procedures. Targeted interventions should be implemented for families with young children and those with grandparent caregivers in order to enhance overall vaccination coverage.
