Abstract: Highlights•Propose a novel vaccination game model with the vaccine efficacy and the adaptive perceived vaccination cost.•For the moderate vaccination cost, the introduction of adaptive perception can promote vaccination behavior.•The population with a smaller perception fluctuation has a more pronounced improvement in vaccination behavior.•Vaccination behavior is constrained by a significant number of free-riders when vaccine effectiveness is high.•The free-riders are mainly individuals with low-degree, when vaccine effectiveness is high.
