论文摘要
这项研究旨在从统计上评估疫苗接种对SARS-COV-2的有效性。为了研究疫苗在现实世界中的影响，必须研究COVID-19的期间与疫苗接种之间的关系是必不可少的。我们研究了不同国家在疫苗接种水平的不同国家的感染率和死亡率。在这项研究中，接受所需疫苗接种剂量的人被认为是完全疫苗接种的。根据完全接种疫苗的人口的百分比，各国被归类为几组。尽管对疫苗有效性的高级研究可能无法为个人水平差异提供太多的见解，但必须进行全球分析，以推断疫苗接种作为大流行的控制量度。
This study aims to statistically assess the effectiveness of vaccination against SARS-CoV-2. It is indispensable to investigate the relationship between Covid-19 deadliness and vaccination in order to study the impact of vaccine in real-world. We studied rates of infection and death due to Covid-19 in different countries with respect to their levels of vaccination. People who received the required dose of vaccination were considered as fully vaccinated in this study. Based on the percentage of fully vaccinated population, countries were categorized into several groups. Though a high-level study on the vaccine effectiveness may not provide much insight for individual level differences, a global analysis is imperative to infer the influence of vaccination as a controlling measure of the pandemic.
