As the world yearns for a return to normal life after more than a year of living through the pandemic, countries are racing to deliver vaccines that should slow — and hopefully stop — the spread of the coronavirus.
Successfully doing so will depend on an array of factors, from manufacturing and transporting billions of doses, ensuring that rich nations don’t monopolize the world’s vaccine supply, and, crucially, actually getting doses into people’s arms.
The charts and maps below will update to show the most recent data on the largest vaccination rollout in history, in the US and across the globe.
Vaccine rollout by state
There are notable differences from state to state in how quickly the vaccines are being given to people.
The first two vaccines approved for emergency use in the US, developed by the companies Pfizer/BioNTech and Moderna, are designed to be given in two doses several weeks apart. The Johnson & Johnson vaccine authorized for use in late February requires only one dose. So to vaccinate everyone in the US will eventually mean giving somewhere between 100 and 200 doses per 100 people across each state and territory — or a total of between 330 million and 660 million doses for the entire nation. It’s a huge logistic challenge.
As the Biden administration took over, promising stronger federal coordination of the vaccine rollout, the number of shots given daily increased steadily, hitting a peak of more than 3 million doses a day in April. In May, facing a sharp decline in the number of people getting shots, Biden announced a new strategy aiming to vaccinate harder-to-reach communities, shifting from mass vaccination centers to more mobile clinics and walk-in appointments at pharmacies. Still, there are concerns that the vaccination drive is leaving poorer people and communities of color behind.

Vaccine rollout timeline
This chart shows the number of vaccines administered per 100 people for each state from the beginning of 2021. The top three states and US national numbers are highlighted. Type the name of any other state or US territory into the search bar and select to add to the chart.
This chart shows the daily number of vaccine doses given to people across the nation from the start of 2021. Because of spikes in the data due to lags in reporting, the line showing the 7-day rolling average of doses given gives a clearer idea of whether the rollout is accelerating or slowing.
Vaccine rollout by nation
More countries appear on this map showing vaccine doses given per 100 people because these numbers are more widely reported.
Most of the countries with the highest vaccination rates so far have very small populations. The US is ahead of most other major nations in vaccine rollout. Search or navigate through this table to see how each nation is doing.

Status of leading vaccines
This table documents the status of leading COVID-19 vaccines, showing authorizations for use in the US and other seleceted markets, plus prices from information on purchase agreements compiled by UNICEF, where available.
The vaccines from Pfizer/BioNTech and Moderna, with clinical trial results indicating that they are more than 90% effective in preventing disease, are based on a new technology that delivers a sequence of RNA that makes our own cells produce viral proteins, triggering an immune response.
The drawback is that these vaccines are more expensive than those made by splicing genetic material from the coronavirus into a disabled version of another virus, such as those produced by the Anglo-Swedish company AstraZeneca, based on research from Oxford University, Johnson & Johnson, and Russia’s Gamaleya Research Institute.
Other leading vaccines are based on inactivated versions of the coronavirus, a longstanding approach to making vaccines, or subunits of proteins from the virus.
