As part of the National Strategy for the COVID-19 Response and Pandemic Preparedness pdf icon[24 MB, 200 Pages]external icon CDC is committed to making sure that safe, effective vaccines are distributed and administered as quickly as possible. Because the supply of vaccine is currently limited, CDC made vaccine rollout recommendations. Each state then makes its own plan for who will be vaccinated first and how people can get a vaccine once it is available to them.
The map below shows the percentage of first doses of vaccines that have been administered in each state from their supply, which can be used to understand how states are using their supply to initiate vaccination within their community.
The majority of U.S. states and territories have administered at or above 81% of their first vaccine doses delivered.
When a jurisdiction is allocated vaccine doses, they are allocated first and second doses at the same time. First doses are available for ordering immediately; second doses are available for ordering 2 or 3 weeks later, depending on the vaccine product. However, vaccine orders and deliveries do not specify if the vaccine is to be administered as a first dose or a second dose. Jurisdictions are instructed to use the delivered supply (first and second doses combined) to best meet the current needs of their community. For the denominator used to calculate the percentages below, the number of doses delivered designated as “first doses” is assumed to align with how the vaccine has been allocated nationally.
To maintain inventory, some vaccine will always be kept in supply; so percentages are not expected to reach 100%.
