The article introduces the Our World in Data COVID-19 vaccination dataset, a global public dataset that tracks the scale and rate of COVID-19 vaccine rollouts worldwide. As of April 7, 2021, the dataset covers 169 countries and includes data on the total number of vaccinations administered, first and second doses, daily vaccination rates, and population-adjusted coverage. The dataset is regularly updated and will be maintained as the global vaccination campaign progresses. It aids policymakers and researchers in understanding the current and potential vaccine rollout rates, interactions with non-vaccination policies, and the impact of vaccinations on pandemic outcomes such as transmission, morbidity, and mortality. The dataset is widely used by journalists, policymakers, researchers, and the public, and has been used to highlight global inequalities in vaccine access and to inform public messaging on vaccine hesitancy. The article also discusses the limitations of the dataset, including the need for timely and complete data from countries and the reliance on official sources.The article introduces the Our World in Data COVID-19 vaccination dataset, a global public dataset that tracks the scale and rate of COVID-19 vaccine rollouts worldwide.
