Many countries that had early access to COVID-19 vaccines implemented vaccination strategies that prioritized health care workers and the elderly. As barriers to access eased, vaccine prioritization strategies have been relaxed. However, these strategies are still an important tool for decision makers to manage new variants, plan for future booster shots, or stage mass vaccinations. This paper explores the impact of vaccine prioritization strategies using networks that represent communities with different demographics and connectivity. The impact of vaccination is compared to non-medical intervention to reduce transmission. Several sources of uncertainty are considered, including vaccine willingness and mask effectiveness. This paper finds that while prioritization strategies can have a large impact on reducing deaths and peak hospitalization, selecting the best strategy depends on community characteristics and the desired objective. Additionally, in some cases random vaccination performs as well as more targeted prioritization strategies. Understanding these trade-offs is important when planning vaccine distribution.
许多较早获得新冠疫苗的国家实施了优先考虑医护人员和老年人的疫苗接种策略。随着疫苗获取障碍的缓解,疫苗优先策略已有所放宽。然而,这些策略仍是决策者应对新变种、规划未来加强针接种或开展大规模疫苗接种的重要工具。本文利用代表不同人口结构和连通性社区的网络,探讨了疫苗优先策略的影响。将疫苗接种的影响与减少传播的非医疗干预措施进行了比较。考虑了几个不确定性来源,包括疫苗接种意愿和口罩有效性。本文发现,虽然优先策略对减少死亡和住院高峰可能有很大影响,但选择最佳策略取决于社区特征和预期目标。此外,在某些情况下,随机接种与更具针对性的优先策略效果相当。在规划疫苗分发时,理解这些权衡很重要。
