Evidence fails to capture disparities amongst African countries in terms of the measure of administered COVID-19 vaccine doses per 100 people. Assessment of data on doses secured, administered, and supplied was undertaken to investigate quantitative measures that impacted COVID-19 vaccine deployment, thereby emphasizing distribution and supply indicators. We employ a full linear regression to identify independent variables that have an impact on vaccination rates, including macroeconomic indicators such as World Bank Income Classification, Gross Domestic Product (GDP) per capita and various indices such as Health Access and Quality Index, Human Development Index, Global Peace Index, Education Index, Political Stability Index and Government Effectiveness. This analysis aims to construct a statistical model utilizing regression analysis to identify key drivers of COVID-19 vaccine deployment in Africa and offer insights into vaccination disparities in the continent. Recognizing the global importance of achieving high vaccination rates, the study sheds light on specific challenges faced by individual countries within Africa, thereby emphasizing the need for tailored efforts. Beyond COVID-19, the research contributes to understanding the relationship between vaccination rates and social indicators that, potentially impact broader public health concerns and global vaccination programs. This study provides a foundation for informed policymaking to enhance vaccine accessibility, inform targeted programs, and improve individual health systems, thereby addressing broader implications for global health.
在每 100 人中接种的 COVID-19 疫苗剂量方面,没有证据表明非洲国家之间存在差异。评估了已获得、管理和供应的剂量数据,以研究影响 COVID-19 疫苗部署的定量措施,从而强调分配和供应指标。我们采用完全线性回归来确定对疫苗接种率有影响的自变量,包括世界银行收入分类、人均国内生产总值 (GDP) 等宏观经济指标以及卫生可及性和质量指数、人类发展指数、全球和平指数、教育指数、政治稳定指数和政府效能等各种指数。该分析旨在利用回归分析构建一个统计模型,以确定非洲 COVID-19 疫苗部署的关键驱动因素,并深入了解非洲大陆的疫苗接种差异。认识到实现高疫苗接种率的全球重要性,该研究揭示了非洲个别国家面临的具体挑战,从而强调了有针对性努力的必要性。除 COVID-19 之外,该研究还探讨了疫苗接种率与社会指标之间的关系,这些指标可能会影响更广泛的公共卫生问题和全球疫苗接种计划。本研究为制定知情的政策提供了基础,以提高疫苗的可及性、为有针对性的计划提供信息,并改善各个卫生系统,从而为全球健康带来更广泛的影响。
