The international COVID-19 vaccination dataset that we make available on this page is updated each morning (London time), using the most recent official numbers from governments and health ministries worldwide up to the previous day. The population estimates we use to calculate per-capita metrics are all based on the last revision of the United Nations World Population Prospects. A full list of our country-specific sources is available at the bottom of this page, and we also answer frequently-asked questions there.
