Vaccine hesitancy is modeled as an endogenous decision within a behavioral epidemiological model with endogenous agent activity. It is shown that policy interventions that directly target costs associated with vaccine adoption may counter vaccine hesitancy whereas those that manipulate the utility of unvaccinated agents will either lead to the same or lower rates of vaccine adoption. This latter effect arises with vaccine passports whose effects are mitigated in equilibrium by reductions in viral/disease prevalence that themselves reduce the demand for vaccination.
疫苗犹豫被建模为具有内生主体活动的行为流行病学模型中的内生决策。研究表明，直接针对与疫苗接种相关成本的政策干预措施可能会对抗疫苗犹豫，而那些操纵未接种疫苗者效用的措施要么会导致相同的疫苗接种率，要么会导致更低的疫苗接种率。后一种效应出现在疫苗护照的情况下，其效果在均衡状态下会因病毒/疾病流行率的降低而减弱，而病毒/疾病流行率的降低本身会减少对疫苗接种的需求。
