Infographic: The Uneven Covid-19 Vaccine Rollout

U.S. President Biden has set a goal for 70 percent of the world's population to be vaccinated against Covid-19 by the end of 2022 - currently almost one-third of the world's population has received the full amount of doses prescribed by the vaccination protocol, according to Our World in Data. Speaking at the United Nations General Assembly, Biden said: "To beat the pandemic here, we need to beat it everywhere. And I made and I'm keeping the promise that America will become the arsenal of vaccines as we were the arsenal for democracy during World War II."

While the global vaccine rollout is clearly still a long way from reaching this target, this infographic shows that it has also been uneven. The highest proportion of the population fully vaccinated is in Europe, at 51 percent. North America is close behind with 46 percent. Africa has the furthest to go - just four percent are fully vaccinated there.

So what is Biden's plan? According to reporting by AP: "The U.S. purchase of another 500 million shots brings the total U.S. vaccination commitment to more than 1.1 billion doses through 2022. About 160 million shots supplied by the U.S. have already been distributed to more than 100 countries, representing more donations than the rest of the world combined."
