The present study aimed to identify the factors associated with the distribution of the first doses of the COVID-19 vaccine. In this study, we used 9 variables: human development index (HDI), gross domestic product (GDP per capita), Gini index, population density, extreme poverty, life expectancy, COVID cases, COVID deaths, and reproduction rate. The time period was until February 1, 2021. The variable of interest was the sum of the days after the vaccine arrived in the countries. Pearson's correlation coefficients were calculated, and t-test was performed between the groups that received and did not receive the immunizer, and finally, a stepwise linear regression model was used. 58 (30.4%) of the 191 countries received the SARS-CoV-2 vaccine. The countries that received the most doses were the United States, China, the United Kingdom, and Israel. Vaccine access in days showed a positive Pearson correlation HDI, GDP, life expectancy, COVID-19 cases, deaths, and reproduction rate. Human development level, COVID-19 deaths, GDP per capita, and population density are able to explain almost 50% of the speed of access to immunizers. Countries with higher HDI and per capita income obtained priority access.
本研究旨在确定与 COVID-19 疫苗首剂分布相关的因素。本研究使用了 9 个变量：人类发展指数（HDI）、国内生产总值（人均 GDP）、基尼指数、人口密度、极端贫困、预期寿命、COVID 病例、COVID 死亡和繁殖率。时间范围截至 2021 年 2 月 1 日。感兴趣的变量是疫苗抵达各国后的天数总和。计算了 Pearson 相关系数，并对接受和未接受免疫剂的组进行了 t 检验，最后使用逐步线性回归模型。191 个国家中的 58 个（30.4%）接种了 SARS-CoV-2 疫苗。接种疫苗最多的国家是美国、中国、英国和以色列。疫苗接种天数呈正 Pearson 相关 HDI、GDP、预期寿命、COVID-19 病例、死亡和繁殖率。人类发展水平、COVID-19 死亡、人均 GDP 和人口密度能够解释接近 50%的疫苗接种速度。人类发展指数和人均收入较高的国家优先获得疫苗。
