社会规范对疫苗接种的看法有着深远的影响。人们对疫苗接种的态度反映了他们对疫苗接受和感染风险之间权衡的内在认识。在这里，我们考虑疫苗接受和感染的恐惧，其中的社会动力学嵌入到数学流行病学框架中的疫苗接种方面的循环流行病动力学模型的新路径。除了已经建立的疫苗接种博弈模型，我们开发了一个称为循环平均场（CMF）模型维斯循环行为（CBH）模型。在CMF模型中，我们假设，与疾病传播一样，疫苗接种的推进过程也通过人与人之间的接触发生，而疫苗接种的收缩（低疫苗接种接受度）也被整合到个体的社会互动中。我们分析研究模型框架，通过丰富的相图。广泛的数值模拟表明，有效的疫苗接种可能会有意义地降低社区感染风险。如果能够培养对疫苗接种的积极态度和对疾病风险的公平认识，就可以提高疫苗接种率，从而减少流行病的流行。我们的调查可能会提供一个新的流行病学动力学概念，认为社会动力学嵌入到疫苗接种率的变化。(C)2021爱思唯尔有限公司版权所有。
Social norms have a profound influence on the perception of vaccination. People's attitudes toward vaccination reflect their inherent recognition of the trade-off between vaccine acceptance and risk of infection. Here we model a new path of cyclic epidemic dynamics in vaccination aspects by considering the vaccine acceptance and fear of infection, where the social dynamics are embedded into the mathematical epidemiological framework. Besides the already established vaccination game models, we develop a model called the cyclic mean-field (CMF) model vis-a-vis the cyclic behavioral (CBH) model. In the CMF model, we presume that, like disease transmission, the propelling process for vaccination also occurs through human contact, and the deflating vaccination (low vaccination acceptance) is also integrated into the social interactions of individuals. We analytically investigate the model framework through a rich phase diagram. Extensive numerical simulation suggests that effective vaccination may meaningfully reduce the community risk of infection. Provided a proactive attitude toward vaccination and fair recognition of disease risk can be developed, the vaccination uptake can be enhanced, thereby resulting in reduced epidemic prevalence. Our investigation might provide a new epidemiological dynamics concept that considers the social dynamics embedded into the alteration rate of vaccination. (C) 2021 Elsevier B.V. All rights reserved.
