动态网络上的COVID-19疫苗接种策略

COVID-19 vaccination strategies on dynamic networks

摘要:

由SARS-CoV-2引起的冠状病毒病(COVID-19)已成为全球公共卫生问题。世界上很大一部分人需要接种疫苗,以阻止疾病的迅速蔓延。除了优先考虑人群中的弱势群体接种疫苗外,理想的基于学位的疫苗接种策略还使用细粒度的联系网络来优先考虑疫苗接种者。由于需要大量的具体联系信息,这种策略成本高昂且不切实际。它也没有捕获间接饥荒或基于气溶胶的传播。我们最近提出了一种新的疫苗接种策略,称为基于个人运动的疫苗接种(IMV),它考虑到直接和间接传播,并基于人们访问的地方类型。IMV在流感样疾病中显示出成本效益。本文研究了IMV在COVID-19中的应用,使用其记录的传输参数。我们进行大规模的计算机模拟的基础上,全市范围内的经验流动数据集,以评估该战略的性能和实用性。实验结果表明,该策略的效率是随机接种的近5倍,与基于度的策略相比具有更高的效率,同时显著降低了数据汇集的需求。

英文摘要:

Coronavirus disease (COVID-19), which was caused by SARS-CoV-2, has become a global public health concern. A great proportion of the world needs to be vaccinated in order to stop the rapid spread of the disease. In addition to prioritising vulnerable sections of the population to receive the vaccine, an ideal degree-based vaccination strategy uses fine-grained contact networks to prioritise vaccine recipients. This strategy is costly and impractical due to the enormous amount of specific contact information needed. It also does not capture indirect famine or aerosol-based transmission. We recently proposed a new vaccination strategy called Individual's Movement-based Vaccination (IMV), which takes into account both direct and indirect transmission and is based on the types of places people visit. IMV was shown to be cost-efficient in the case of influenza-like diseases. This paper studies the application of IMV to COVID-19 using its documented transmission parameters. We conduct large scale computer simulations based on a city-wide empirical mobility dataset to evaluate the performance and practicability of the strategy. Results show that the proposed strategy achieves nearly five times the efficiency of random vaccination and performs comparably to the degree-based strategy, while significantly reducing the data collection requirements.
