While countries across the globe attempt to speed up their vaccine distribution, Israel has the highest vaccination rate in the world, with more than 40 doses per 100 people followed by the UK, the U.S., Italy, and France.
Israel began vaccinations on December 19th, aiming to inoculate the majority of its population by April.
An efficient health care system has helped with the fast distribution, as the digitized system allows everyone receiving the vaccine to be registered by the country's health ministry.
Israel also plans to ban all passenger flights in and out of the country to prevent any variants of the virus from entering.
Meanwhile, the U.S. aims to give 100 million shots in the first 100 days of new President Joe Biden's administration.
"The supply should be steadily increasing. And what I'm concerned about in particular is making sure that we have enough distribution channels set up."
A complex healthcare system is proving to be a challenge for the U.S. when trying to get supplies to local health centers.
This is because a lot of services are run by different providers within each state, which can operate independently.
Vaccine programs differ greatly across each state. Alaska had given out more than 9 doses per 100 people as of January 20th Alabama less than 3.
Over in Europe, distributions were halted because of a cut in vaccine deliveries.
Pfizer said last week that it was delaying shipments for the next few weeks because of increased demand at its Belgian processing plant.
According to BBC News, Italy and Poland have threatened to take legal action in response.
Italy has been told to expect a 20-percent cut in the Pfizer-BioNTech vaccine over the next week, and Poland saw a 50-percent drop in the number of vaccines delivered this week.
