Seasonal influenza (Panel A) and HBV (Panel B) vaccination coverage among HCWs in Croatian hospitals, stratified by season/year. Each dot represents one hospital while bars represent the medians with IQRs. Statistical significance was calculated using the Kruskal–Wallis and post hoc multiple comparison tests. In (Panel A), significant decreases in 2010–2011 and 2011–2012 post-pandemic vaccination coverage is seen in comparison to the four pre-pandemic seasons. Meanwhile, HBV vaccination coverage was stable during the period studied (p = 0.07) (Panel B).
