Prevalence and factors influencing influenza vaccination among health care workers in China: a systematic review and meta-analysis.
Synthesis in Frontiers in public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Aims: To systematically evaluate the influenza vaccination rate among health care workers in China and identify influencing factors. Design: Systematic review and meta-analysis of cross-sectional studies. Data Sources: CNKI, Wanfang, VIP, Web of Science, PubMed, Cochrane Library, Scopus, and Embase, searched from database inception to October 4, 2025. Review Methods: Two reviewers independently screened studies, extracted data, and assessed study quality using the Agency for Healthcare Research and Quality (AHRQ) tool. Random-effects models were used to pool vaccination rates and odds ratios. Heterogeneity was assessed using I Results: Forty-nine studies involving 111,544 participants were included. 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. Conclusion: 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. Impact: 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. Patient or Public Contribution: No patient or public contribution. Systematic review registration: PROSPERO registration CRD: 42024553631.
