Vaccine adoption during pandemics can be interpreted through the lens of innovation diffusion theory, wherein social dynamics, particularly the outgroup aversion effect, significantly shape acceptance rates.[1][2] We investigate how vaccine adoption dynamics influenced by outgroup aversion impact pandemic trajectories, with a focus on the case of South Korea. An agent-based model (ABM) grounded in innovation diffusion principles was developed, integrating detailed regional demographic data and inter-regional mobility patterns specific to South Korea.[3] The model explores the relationship between the intensity of outgroup aversion and disease transmission dynamics. Results indicate that heightened outgroup aversion substantially reduces maximum vaccine adoption rates, emphasizing the critical role of peer influence and neighborhood vaccination behaviors in agents' decision-making processes.[4] Although constrained by reliance solely on empirical demographic and mobility data without encompassing additional socio-behavioral factors, this study underscores the pivotal impact of outgroup aversion on vaccine acceptance. Future refinements incorporating broader social dynamics could offer deeper sociological insights into pandemic management strategies.
