Seasonal influenza (Panel A) and HBV (Panel B) vaccination coverage among healthcare workers in Croatian hospitals, stratified by occupation and year. The bars represent medians with IQRs. Statistical significance was calculated using the Kruskal–Wallis and post hoc multiple comparison tests. Statistical analysis showed significant differences among physicians, graduate nurses and practical nurses (p = 0.01). Furthermore, significant decreases in 2011–2012 were observed (*, p < 0.05)) (Panel A). Meanwhile, HBV vaccination coverage was the lowest among housekeeping personnel (p = 0.001) (Panel B).
