Percentage of the first vaccine dose administered by the U.S. states and territories

As part of COVID-19 National strategy for response and epidemic preparedness pdf icon The CDC is committed to ensuring this Safe, Effective Vaccines are distributed and administered as soon as possible.

To help understand vaccine administration, the CDC has created the following map to show the percentage of the first dose of vaccine administered in each jurisdiction from their supply. This information can be used to better understand how states are using their supplies to initiate vaccinations within their communities.

Weekly total percentage of the first dose administered on the basis of field vaccine supply

Most U.S. states and territories administer .3 74..3% or more of their first vaccine delivery.


When a jurisdictional vaccine dose is allocated, the jurisdiction distributes the first and second doses at the same time.

  • The first dose is available for immediate order;
  • The second dose is available for order after 2 or 3 weeks depending on the visa product.

However, the vaccine order and delivery do not specify if the vaccine should be administered as a first dose or a second dose. Courts are instructed to use delivery supplies (first and second dose) jointly to best meet the current needs of their community.


For the denominator used to calculate the following percentages, the number of doses specified as “first dose” is assumed to be based on how the number is allocated nationally. To maintain inventory, some vaccines will always be in supply; Therefore, the percentage is not expected to reach 100%. Please see the footnote for more information.
