Influenza vaccination uptake and associated factors among healthcare workers in Chengdu’s maternal and child health institutions in the post-pandemic era

Purpose: This study assessed influenza vaccination uptake, knowledge, beliefs, and willingness among healthcare workers (HCWs) in maternal and child health (MCH) institutions in Chengdu in the post-COVID-19 era and identified factors associated with vaccination behavior. Methods: -tests/one-way ANOVA), and hierarchical multivariable logistic regression. Results: = 0.377) identified independent correlates of vaccination uptake, including older age [odds ratio (OR) = 1.029 per year], master's degree or above (OR = 2.067), working in secondary-level MCH hospitals (OR = 5.377) or outpatient/preventive-care departments (OR = 1.682), being a nurse (OR = 1.804) or administrative staff member (OR = 3.262) versus physician, higher belief score (OR = 1.062 per point), and, most strongly, willingness to vaccinate (uncertain vs. unwilling: OR = 3.431; willing vs. unwilling: OR = 23.296). Conclusion: Influenza vaccination coverage among HCWs in Chengdu MCH institutions remained suboptimal in the post-pandemic period, with a clear intention-behavior gap. Uptake was associated with more favorable beliefs, higher willingness, older age, higher education, and institutional/departmental and occupational factors. Targeted strategies to strengthen confidence, improve access and convenience, and tailor interventions to specific departments and job categories are needed to increase coverage.
