| Outline of Final Research Achievements |
This study has successfully explored how people’s decision-making process with social dilemma of individual vaccination, namely whether or not to be vaccinated is influenced in a complex realistic social system, by means of the model of dynamics for epidemic spreading on a social network applied to evolutionary game theory. On underlying networks, both epidemic and information of agent’s strategy are transferred, where the former is modeled by SIR and the latter is emulated as a spatial evolutionary game. Simulation results imply that both the vaccination acceptance fraction and final epidemic size are significantly affected by how strategy updating happens; namely whether he/ she copying from a neighbor or imitating a social trend, and underlying network topologies. The study poses one example of how the social physics helps to understand complex phenomenon taking place in a real world.
