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-19 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-19 vaccination dataset that we make available on this page. It is updated each morning, with the most recent official numbers up to the previous day.

• Data sources: at the end of this page you find a detailed list of all our country-specific 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 repository 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.

The following charts show the breakdown of vaccinations by those that have been partly or fully vaccinated. A person is considered partly vaccinated if they have received only one dose of a 2-dose vaccine protocol. A person is considered fully vaccinated if they have received a single-dose vaccine or both doses of a two-dose vaccine.

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

Daily number of COVID-19 vaccinations administered

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 who 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 who 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 following charts show the number of booster doses administered. Booster doses are doses administered beyond those prescribed by the original vaccination protocol — for example a third dose of Pfizer/BioNTech vaccine, or a second dose of Johnson & Johnson vaccine.

The following charts provide data on the share of people that have been vaccinated against COVID-19 by age group. This is provided as three metrics: the share that have received at least one dose; the share that have been fully vaccinated; and the share that are only partly vaccinated.

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

Share that have received at least one dose by age

The following chart shows the share of the population in each age group that have received at least one dose of the COVID-19 vaccine. This metric includes those that are either partly or fully vaccinated.

Fully vaccinated by age

The following chart shows the share of the population in each age group that are fully vaccinated against COVID-19. This represents the share that have received all doses prescribed by the vaccination protocol.

Partly vaccinated by age

The following chart shows the share of the population in each age group that are only partly vaccinated against COVID-19. For a two-dose vaccine schedule, this would be people that have received only one dose.

Those who are fully vaccinated are not included. This means this metric will decrease as people receive their second dose.

The following chart shows the cumulative number of doses administered, broken down by vaccine manufacturer. This is only available for a select number of countries which report the necessary data.

These charts show the cumulative number of doses donated to the COVAX initiative by different countries, broken down by whether the donations have only been announced, actually donated, or delivered to the recipients. This is only available for a select number of countries for which the COVID-19 Task Force reports the necessary data.

The second chart shows the number of doses donated per million dollars of GDP of the donating country.

This interactive chart maps government policies on COVID-19 vaccination. Note that this only tracks policies on the availability of vaccinations. It does not track the number of people who have been vaccinated.

Countries are grouped into six categories:

• No availability
• Availability for ONE of following: key workers/ clinically vulnerable groups / elderly groups
• Availability for TWO of following: key workers/ clinically vulnerable groups / elderly groups
• Availability for ALL of following: key workers/ clinically vulnerable groups / elderly groups
• Availability for all three plus partial additional availability (select broad groups/ages)
• Universal availability

The Imperial College London YouGov Covid-19 Behaviour Tracker Data Hub gathers global insights on people’s behaviors in response to COVID-19. This survey covers public behaviors and attitudes ranging from mask-wearing to self-isolation, social distancing, symptoms and testing.

The following two charts show monthly data from this survey on the willingness of people to get vaccinated against COVID-19. Survey respondents were presented with the following statement: “If a COVID-19 vaccine were made available to me this week, I would definitely get it.” Respondents were asked to react to this statement on a 1 to 5 scale, ranging from “Strongly agree” (1) to “Strongly disagree” (5).

Based on this scale, we consider respondents to be willing to get a COVID-19 vaccine if they selected 1 or 2, unwilling to get a COVID-19 vaccine if they selected 4 or 5, and uncertain if they are willing to get a COVID-19 vaccine if they selected 3.

Both charts below show the share of a country’s population that has received at least one dose of a COVID-19 vaccine in comparison to the share of the population that is unvaccinated, where the share of the unvaccinated population is separated into those who would be willing vs. unwilling vs. uncertain if they would get a COVID-19 vaccine if it was made available to them this week.¹

The first chart shows this data for a single country over time, while the second chart shows the same data for multiple countries at a single point in time.

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:

Why do the figures displayed on this page look different from the ones published by my government?

In some cases, the vaccination figures on this page can look different from the ones reported by a government. Most often it is not because of the numerator (number of people vaccinated) but instead because of the denominator (number of people in the population). This usually happens for two main reasons:

1. The official data reports the vaccination coverage in terms of the share of people vaccinated in the population eligible for vaccination (very often, among adults only). Our priority is to make our data comparable between countries — regardless of criteria for eligibility, which tend to vary across countries and across time. For this reason, we always use the total population of the country (i.e. people of all ages) as the denominator.
2. The official data uses a different population estimate. The population estimates we use come from the United Nations World Population Prospects. We use this data for its reliability, its consistent methods, and because it makes our work much easier (see below for more information).

What population data are the per-capita metrics based on?

The population estimates we use come from the United Nations World Population Prospects. We use this data for its reliability, its consistent methods, and because it makes our work much easier. The exact values can be viewed in our GitHub repository.

The United Nations estimates may not always reflect the latest censuses or national figures—but there are several reasons why we use this data over country-by-country national population estimates.

• The UNWPP dataset is the standard in research. The main reason is that it uses a reliable and standardized methodology for all countries. For example, if we used individual country data, some may include overseas workers, expats, undocumented immigrants, etc. but others wouldn’t.
• Using data from the UN allows us to get accurate population estimates for all territories in the world very easily. Finding and maintaining estimates based on national censuses would be very time-consuming for our small team, without bringing much additional value to our work.
• Other reasons include the availability of yearly data (national censuses are only conducted every few years), and avoiding double-counting in cases of border disputes.

For all these reasons, the UN data is the best solution to bring accurate per-capita metrics to our COVID data.

Can the value of per-capita metrics exceed 100%?

The population estimates we use to calculate per-capita metrics are all based on the last revision of the United Nations World Population Prospects. The United Nations estimates may not always reflect the latest censuses or national figures. Additionally, it’s important to bear in mind that in some territories, vaccination coverage may include non-residents (such as tourists and foreign workers). For these reasons, per-capita metrics may sometimes exceed 100%.

What is the definition of a fully-vaccinated person?

In our data, fully-vaccinated people are those who have received all doses prescribed by their vaccination regimen (e.g. 2 doses for Pfizer/BioNTech, Moderna, Oxford/AstraZeneca, etc. and 1 dose for Johnson & Johnson, CanSino, etc.).

Some countries also allow for alternative definitions, such as having been infected with SARS-CoV-2 in the past and having received 1 dose of a two-dose regimen. We currently ignore these alternative definitions to preserve the common definition of fully vaccinated, i.e. all doses required in the vaccine regimen. This allows for an optimal comparability between countries.

What classification are the income groups based on?

The income groups we use come from the World Bank income classification. The exact list of countries can be viewed in our GitHub repository.

Why isn’t my country shown by default on a chart? How do you choose which countries are shown?

Due to the limited space on our charts and the number of countries in the world, we unfortunately cannot show every country in the world by default. On each chart of this page, we therefore choose a default selection of countries based on a mix of criteria: mainly total population, but also number of vaccine doses administered and share of the population vaccinated. These lists are updated about once a month.

In the future, we plan to develop new features that would allow the list of countries to automatically adapt to the region of each visitor, and if they allow it, to use cookies to save their default list on their computer.

How can we best estimate how many people have been vaccinated globally?

Because some countries — notably China, as of August 2021 — do not report breakdowns between first and second doses administered, we cannot know the exact number of people with at least 1 dose and people fully vaccinated in the world. The figures displayed on our charts for “World” only include data from countries that do publish this more precise information. Therefore, as long as some countries are only reporting partial data, these figures will underestimate the real number of people vaccinated and fully vaccinated globally.

Based on the number of doses administered, it is however possible to calculate a lower and upper bound of how many people have been vaccinated in these countries. For example, if 500 million doses have been used in China, they must have been administered to at least 250 million people (with 2 doses each), and up to 500 million people (with only 1 dose each).

We recommend citing the figure on our charts as the “confirmed number of people with at least 1 dose”.

A good proxy for estimating the “complete number of people with at least 1 dose” is:

• [confirmed number of people with at least 1 dose] + ([total doses administered in China] / 2) as a lower-bound estimate;
• [confirmed number of people with at least 1 dose] + [total doses administered in China] as a higher-bound estimate.

My country has started vaccinating its population. Why is it missing from the charts?

Other countries that are not shown in our data may 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. If you’re aware of an official source reporting numbers, please let us know using the “Feedback” button at the bottom of your screen.

Are participants in vaccine clinical trials included in your data?

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.

How do you report vaccinations performed in Israel and Palestine?

In our dataset and charts on COVID-19 vaccinations, we report vaccinations performed in Israel and Palestine separately.

The vaccination data is needed to understand how the pandemic is evolving. For this it is key to bring together the vaccination data with data on COVID-19 cases and COVID-19 deaths. Global health institutions that report on the pandemic are reporting these metrics separately: 

• The World Health Organization reports the measures for Israel separately from Palestine in its data.
• Johns Hopkins University also reports Israel separately from Palestine in its data on cases & deaths of COVID-19, which has been used worldwide in the last year.

Reporting the data for Palestine and Israel separately also allows us to show their respective reported vaccination levels. It makes clear what the respective vaccination levels are, as reported by the Government of Israel and the Palestinian Ministry of Health.

Finally, our dataset on COVID-19 vaccinations is sourced from official data published by governments and ministries of health from countries around the world. This is also the case for Israel and Palestine. We show figures for Palestine and Israel separately, as they are reported separately by the Government of Israel and the Palestinian Ministry of Health. 

The Populations Division of the United Nations reports population figures for countries around the world, and we are relying on their latest data (from their 2019 revision) for countries around the world of. They report a population of 8,655,541 people for Israel and a population of 5,101,416 people for Palestine.

The resulting shares of people vaccinated in Israel and Palestine can be seen in our COVID-19 Data Explorer.
