鉴于全球 2019 冠状病毒病 (COVID-19) 疫苗短缺和疫苗分配不公平,尽管出现了令人担忧的新变种,但疫苗剂量分割可能是减轻公共卫生和经济负担的有效策略。在这项研究中,我们开发了一个结合人口水平传播和个人水平疫苗接种的多尺度模型,以估计印度因剂量分割策略而导致的住院和疫苗接种成本以及减少 COVID-19 死亡的经济效益。我们使用大规模的支付意愿调查数据以及疫苗和住院费用数据来构建模型。我们发现,与全剂量疫苗接种或不疫苗接种的替代方案相比,分次剂量疫苗可能是一种经济上可行的疫苗接种策略。即使出现了具有更高传染性的新变种,剂量节约策略也可以挽救大量生命。使用人口水平传播和个人水平疫苗接种数据的多尺度模型表明,疫苗剂量分割可能是缓解印度 COVID-19 大流行的一种具有成本效益的策略。
Given global Coronavirus Disease 2019 (COVID-19) vaccine shortages and inequity of vaccine distributions, fractionation of vaccine doses might be an effective strategy for reducing public health and economic burden, notwithstanding the emergence of new variants of concern. In this study, we developed a multi-scale model incorporating population-level transmission and individual-level vaccination to estimate the costs of hospitalization and vaccination and the economic benefits of reducing COVID-19 deaths due to dose-fractionation strategies in India. We used large-scale survey data of the willingness to pay together with data of vaccine and hospital admission costs to build the model. We found that fractional doses of vaccines could be an economically viable vaccination strategy compared to alternatives of either full-dose vaccination or no vaccination. Dose-sparing strategies could save a large number of lives, even with the emergence of new variants with higher transmissibility. A multi-scale model using population-level transmission and individual-level vaccination data suggests that vaccine dose fractionation could be a cost-effective strategy for mitigating the COVID-19 pandemic in India.
