The Our World in Data COVID vaccination data

To bring this pandemic to an end a large share of the world needs to be immune to the virus. The safest way to achieve this is with a vaccine. Vaccines are a technology that humanity has often relied on in the past to bring down the death toll of infectious diseases.

Within less than 12 months after the beginning of the COVID pandemic several research teams rose to the challenge and developed vaccines that protect from SARS-CoV-2, the virus that causes COVID-19.

Now the challenge is to make these vaccines available to people around the world. It will be key that people in all countries – not just in rich countries – receive the required protection. To track this effort we at Our World in Data are building the international COVID vaccination dataset that we make available on this page.

• Data sources: At the end of this page you find a detailed list of all our country-specfic sources.

• Open access: As with all of our data we are making this dataset openly available, so that everyone can check and use the data that we bring together. You find the vaccination data in our daily updated Our World in Data COVID-19 Dataset hosted on Github.

This page has a number of charts on vaccination. In the box below you can select any country you are interested in – or several, if you want to compare countries.

All charts on this page will then show data for the countries that you selected.

Total number of COVID-19 vaccinations administered

The following chart shows the total number of COVID-19 vaccination doses administered. Note that this is counted as a single dose, and may not equal the total number of people vaccinated, depending on the specific dose regime (e.g. people receive multiple doses).

The following chart shows the share of the total population that has received at least one dose of the COVID-19 vaccine. This may not equal the share that are fully vaccinated if the vaccine requires two doses. If a person receives the first dose of a 2-dose vaccine, this metric goes up by 1. If they receive the second dose, the metric stays the same.

Total number of people that have received at least one dose of the COVID-19 vaccine

The following chart shows the total number of people that have received at least one dose of the COVID-19 vaccine. This may not equal the number that are fully vaccinated if the vaccine requires two doses. If a person receives the first dose of a 2-dose vaccine, this metric goes up by 1. If they receive the second dose, the metric stays the same.

The following chart shows the share of the total population that has been fully vaccinated against COVID-19. This represents the share that have received all doses prescribed by the vaccination protocol. If a person receives the first dose of a 2-dose vaccine, this metric stays the same. If they receive the second dose, the metric goes up by 1.

This data is only available for countries which report the breakdown of doses administered by first and second doses.

Total number of people that have been fully vaccinated against COVID-19

The following chart shows the total number of people that have been fully vaccinated against COVID-19. This represents the number that have received all doses prescribed by the vaccination protocol. If a person receives the first dose of a 2-dose vaccine, this metric stays the same. If they receive the second dose, the metric goes up by 1.

This data is only available for countries which report the breakdown of doses administered by first and second doses.

The metrics above provide the total number of doses administered — the cumulative doses over time.

The following chart shows the daily number of COVID-19 vaccination doses administered. This is shown as the rolling seven-day average. Note that this is counted as a single dose, and may not equal the total number of people vaccinated, depending on the specific dose regime (e.g. people receive multiple doses).

Daily number of COVID-19 vaccinations administered per 100 people

The following chart shows the daily number of COVID-19 vaccination doses administered per 100 people. This is shown as the rolling seven-day average. Note that this is counted as a single dose, and may not equal the total number of people vaccinated, depending on the specific dose regime (e.g. people receive multiple doses).

The speed at which the first COVID-19 vaccines were developed was extraordinary. We have previously looked into the history of vaccine development. The measles vaccine was found relatively rapidly: it took only 10 years from the discovery of the pathogen to the development of the first vaccine. But for typhoid it took more than a century, and for some diseases for which we’ve known the pathogens for more than a century (like malaria) we still haven’t found an effective vaccine.

The development of a vaccine against COVID-19 has been much faster than the development of any other vaccine. Within less than a year several successful vaccines have already been announced and were approved for use in some countries. 

The hope is that even more manufacturers develop vaccines for COVID-19. This will be important because eventually a very large share of the world population needs to receive a COVID-19 vaccine.

We are on the way to several vaccines against COVID-19 – vaccine trackers monitor the progress:

You can download the full dataset alongside the detailed source descriptions on GitHub.

Note that other countries have also started vaccination campaigns—we’ll add them to our maps and charts as soon as numbers are verifiable based on public official sources.

We do not include participants in the vaccine arm of clinical trials, as this data is not available for many of the hundreds of trials currently taking place.
