The count of COVID-19 vaccine shots administered worldwide topped 3.97 billion as of Wednesday, according to Our World In Data, a tracking website affiliated with Oxford University.
China, where the outbreak originated in late 2019, ranks first globally, with more than 1.58 billion vaccine jabs delivered within the country, according to the available data, followed by India with over 446.16 million jabs.
The US has delivered over 342.61 million shots, followed by Brazil with over 136.51 million.
The vaccination campaigns in Germany (90.29 million), the UK (84.11 million), Japan (81.02 million), and France (69.69 million) also continue apace.
Turkey has so far administered more than 69.24 million vaccine shots, making it ninth worldwide, while over 40.14 million people have received at least one dose of the vaccine.
As COVID-19 vaccines are generally given in two separate doses per person, the count of administered vaccines does not mean that the same number of people has been vaccinated.
Since December 2019, the pandemic has claimed more than 4.17 million lives across the world, with an excess of 195.41 million cases reported, according to the US' Johns Hopkins University.
