Like the death toll from COVID-19 reached amazing heights, countries are rushing to provide vaccines that could slow – and possibly stop – the spread of the coronavirus.
Success will depend on a dizzying array of factors, from conducting massive clinical trials so that vaccines still in development can be approved for use, manufacture and transport in billions of doses, ensuring that rich nations don’t monopolize the global supply of vaccines and, above all, by injecting doses into people’s arms.
The charts and maps below will be updated to show the most recent data on the deployment of what will be the largest immunization program in history, in the United States and around the world.
The deployment of vaccines in the United States has so far been slower than expected. The Trump administration has set itself the goal of giving 20 million vaccinations at the end of 2020. This target was not reached until the end of January. President Joe Biden has pledged to administer 100 million vaccines during his first 100 days in office. Some experts have said that it is not fast enough.
There are notable differences from state to state in how quickly vaccines are given to people. Both vaccines approved for emergency use in the United States so far, developed by companies Pfizer / BioNTech and Modern, are designed to be given in two doses several weeks apart. Some other vaccines still under approval would only require a single dose. So, to vaccinate everyone in the United States, it will ultimately require between 100 and 200 doses per 100 people in each state and territory – for a total of between 330 million and 660 million doses nationwide. It’s a huge logistical challenge.
The vaccines are distributed by the federal government to different states. But as the map above shows, some states administer the vaccines delivered to them faster than others.

Vaccine deployment schedule
This graph shows the number of vaccines administered per 100 people for each state as of the start of 2021. The top three states and US national numbers are highlighted. Type the name of any other US state or territory in the search bar and select to add it to the chart.
Vaccine deployment by country
The United States is ahead of most other countries in vaccine deployment. But Israel is clearly the first leader, reaching a greater proportion of its population than any other nation. Search or browse this chart to see how each nation is doing.
This graph shows the number of vaccines administered per 100 people for each country since the start of 2021. Type the name of any country in the search bar and select to compare its timeline with the United States and the other three countries leaders in vaccine deployment around the world. Only countries that have started their vaccination campaigns will appear.
Status of major vaccines
This table documents the status of major COVID-19 vaccines, showing authorizations for use in the United States and other major markets, as well as pricing information on purchase agreements. compiled by UNICEF, if applicable.
The two main vaccines to date, from Pfizer / BioNTech and Moderna, with clinical trial results indicating they are more … than 90% efficient in disease prevention, are based on new technology which delivers an RNA sequence that allows our own cells to produce viral proteins, triggering an immune response.
The downside is that these vaccines are more expensive than those made by splicing the genetic material of the coronavirus into a deactivated version of another virus, like those produced by the Anglo-Swedish company AstraZeneca, based on research from the University of Oxfordand Russia Gamaleya Research Institute.
Other leading vaccines are based on inactivated versions of the coronavirus, a long-standing approach to vaccine manufacturing, or protein subunits of the virus.
