Objective: We aimed to better understand the impact of the COVID-19 pandemic through analysis of disruptions in a global, regional, and national status of COVID-19 vaccination coverage compared by a global scale, World Health Organization regions, World Bank income groups, and each country.Methods: Global datasets of 237 countries and territories from the World Health Organization Dashboard until March 5, 2022 were used and paired with estimates of COVID-19 vaccination coverage of individual levels which were derived from country level models form World Health Organization Dashboard, Release 1. The numbers of persons vaccinated with at least one dose, persons vaccinated with at least one dose per 100 population, and persons fully vaccinated per 100 population were then calculated and estimated. The data were described by a global scale and stratified by World Health Organization regions (Eastern Mediterranean, Americas, Europe, Southeast Asia, the Western Pacific, and Africa), World Bank income groups (high, upper-middle, lower-middle, and low income), and each country.Results: A total of 4,964,626,775 persons worldwide were vaccinated with at least one dose, which is 63.69 per 100 population administered of COVID-19 vaccines at least one dose, and 56.16 per 100 population were fully vaccinated. The number of persons vaccinated with at least one dose was highest in the Eastern Mediterranean (84.18 per 100 population), followed by the Americas (75.82 per 100 population), South-East Asia (68.97 per 100 population), Europe (66.28 per 100 population), Western Pacific (47.18 per 100 population), and Africa (15.87 per 100 population). Persons fully vaccinated had similar patterns of those vaccinated with at least one dose; Eastern Mediterranean (84.25 per 100 population), the Americas (65.08 per 100 population), Europe (61.59 per 100 population), South-East Asia (55.67 per 100 population), Western Pacific (39.04 per 100 population), and Africa (11.62 per 100 population). The proportion of persons who were vaccinated at least one dose or fully vaccinated was greatest in the high income countries, followed by upper-middle, lower-middle, and low income.
Conclusion:The rate of COVID-19 vaccination with at least one dose and those who were fully vaccinated was estimated to be 63.69 per 100 population and 56.16 per 100 population, respectively. Although the COVID-19 vaccine coverage trajectories points towards global increasement in vaccination, persistent inequality in preventing the COVID-19 pandemic occurred in vulnerable groups such as under-developed and low income countries.
