Data Sheet 1_Prevalence and factors influencing influenza vaccination among health care workers in China: a systematic review and meta-analysis.docx

The pooled influenza vaccination rate was 27% (95% CI: 21–34%). Factors positively associated with vaccination included: age 40–49 years, female gender, monthly income > 3,000 RMB, professional title, prior vaccination history, institutional encouragement or requirement, free vaccination policies, awareness of optimal vaccination timing, and vaccination willingness.</p>Conclusion<p>Influenza vaccination coverage among Chinese health care workers remains inadequate.

Structural interventions-such as free vaccination, institutional encouragement, and on-site services-combined with tailored strategies targeting younger, male, low-income, and vaccine-naïve individuals are recommended. Given the observational nature of the included studies, the potential role of mandatory policies should be interpreted cautiously, pilot implementation in high-risk settings is suggested before broader adoption.</p>Impact<p>This study provides an evidence base for formulating targeted influenza vaccination strategies for health care workers in China, which is crucial for reducing nosocomial infection risk and aligning with global public health goals.</p>Patient or Public Contribution<p>No patient or public contribution.</p>Systematic review registration<p>PROSPERO registration CRD: 42024553631.</p>
