An effective rollout of vaccinations against COVID-19 offers the most promising prospect of bringing the pandemic to an end. We present the Our World in Data COVID-19 vaccination dataset, a global public dataset that tracks the scale and rate of the vaccine rollout across the world. This dataset is updated regularly and includes data on the total number of vaccinations administered, first and second doses administered, daily vaccination rates and population-adjusted coverage for all countries for which data are available (169 countries as of 7 April 2021). It will be maintained as the global vaccination campaign continues to progress. This resource aids policymakers and researchers in understanding the rate of current and potential vaccine rollout; the interactions with non-vaccination policy responses; the potential impact of vaccinations on pandemic outcomes such as transmission, morbidity and mortality; and global inequalities in vaccine access.

In the version of this article initially published, errors occurred in Figs. 2 and 6. Figure 2 showed a lack of alignment between the years presented on gross domestic product (GDP) per capita values across countries. These figures-presented in GDP per capita adjusted for purchasing power parity, measured in international dollars-have now been aligned. This correction was necessary because the most recent year for which GDP data is available from the World Bank is different across countries. The GDP alignment issue will have affected all countries in the dataset, some to a very small (unnoticeable) degree when GDP has not significantly changed year-to-year, but more visibly for countries with strong growth rates (e.g., China). Figure 6 incorrectly indicated that no vaccine for Ebola exists. In fact, the first vaccine against Ebola was approved in the European Union and the USA in 2019. These errors have been corrected in the PDF and HTML versions of this article.
