This study aimed to explore the association between the GDP of various countries and the progress of COVID-19 vaccinations; to explore how the global pattern holds in the continents, and investigate the spatial distribution pattern of COVID-19 vaccination progress for all countries. We have used consolidated data on COVID-19 vaccination and GDP from Our World in Data, an open-access data source. Data analysis and visualization were performed in R-Studio. There was a strong linear association between per capita income and the proportion of people vaccinated in countries with populations of one million or more. GDP per capita accounts for a 50% variation in the vaccination rate across the nations. Our assessments revealed that the global pattern holds in every continent. Rich European and North-American countries are most protected against COVID-19. Less developed African countries barely initiated a vaccination program. There is a significant disparity among Asian countries. The security of wealthier nations (vaccinated their citizens) cannot be guaranteed unless adequate vaccination covers the less affluent countries. Therefore, the global community should undertake initiatives to speed up the COVID-19 vaccination program in all countries of the world, irrespective of their wealth.
本研究旨在探讨各国国内生产总值（GDP）与新冠疫苗接种进展之间的关联；探究全球模式在各大洲的情况，并调查所有国家新冠疫苗接种进展的空间分布模式。我们使用了来自开放获取数据源“Our World in Data”的新冠疫苗接种和GDP综合数据。数据分析和可视化在R-Studio中进行。在人口超过100万的国家中，人均收入与接种疫苗的人口比例之间存在很强的线性关联。人均GDP在各国疫苗接种率的差异中占50%。我们的评估显示，全球模式在各大洲均成立。富裕的欧洲和北美国家在新冠疫情中受到的保护最为充分。欠发达的非洲国家几乎尚未启动疫苗接种计划。亚洲国家之间存在显著差异。除非较不富裕的国家也能实现足够的疫苗接种覆盖率，否则富裕国家（为其公民接种疫苗）的安全无法得到保障。因此，国际社会应采取举措，加快世界各国的新冠疫苗接种计划，无论其贫富状况如何。
