On the site, you'll see data for the total number of vaccines distributed, as well as the total number of people who have received their first dose. Another data panel shows the distribution in long-term care facilities, which are prioritized under current US vaccination guidelines.

As of Thursday, you can see from the CDC's map that the states that have received the most doses per capita so far are: New Hampshire, Connecticut, D.C, Alaska, West Virginia, Kentucky, Tennessee, Oklahoma, New Mexico, Colorado, Iowa, Nebraska, South Dakota, North Dakota, and Montana.

All in all, according to the CDC more than 21 million doses have been distributed.

Data comes from healthcare providers, and the data on the CDC site is expected to be updated thrice-weekly: on Mondays, Wednesdays, and Fridays.
