COVID-19, a disease caused by the new type of coronavirus that emerged in Wuhan, China at the end of 2019, was initially isolated in Wuhan, but later on, other cases emerged in Japan, South Korea and Thailand along with China. At the end of January 2020, Italy announced that the first case of COVID-19 was detected. Thus, attempts to isolate the virus failed and the virus began to spread around the world, causing a global epidemic. Within the framework of the global actions required to prevent and slow down the transmission of COVID-19 many scientists from different countries have achieved astonishing scientific success by developing several safe and effective vaccines in less than a year after this virus was isolated and sequenced. In early 2021, more than 30 million doses of vaccine have been administered, but global vaccination practice has exposed obvious disparities in access to this life-saving vaccine. To investigate the success of global vaccination programs and to reveal what factors affect these programs, the global vaccination dataset and the dataset provided by the United Nations were combined and analyzed. In addition, it was aimed to explore the effects of political, economic, and demographic factors on the vaccination program. When the dataset was analyzed in the context of vaccines, it was observed that 40 countries tend to use one type of vaccine while 27 countries are using two or more vaccines. Looking at the factors that affect the vaccination programs it has been concluded that individuals more likely to be vaccinated are the citizens from countries that are more democratically transparent and have higher GDP per capita and total health expenditure (as a percentage of GDP). Besides, it has been observed that citizens from countries with an approved vaccine developer are also more likely to be vaccinated.
