IF YOU ARE FULLY VACCINATED
CDC has updated its guidance for people who are fully vaccinated. See Recommendations for Fully Vaccinated People.
IMPORTANT UPDATE FOR SCHOOLS
CDC recommends schools continue to use the current COVID-19 prevention strategies for the 2020-2021 school year. Learn more
Important update: Healthcare facilities
CDC has updated select ways to operate healthcare systems effectively in response to COVID-19 vaccination. Learn more
UPDATE
Getting vaccinated prevents severe illness, hospitalizations, and death. Unvaccinated people should get vaccinated and continue masking until they are fully vaccinated. With the Delta variant, this is more urgent than ever. CDC has updated guidance for fully vaccinated people based on new evidence on the Delta variant.
UPDATE
Given new evidence on the B.1.617.2 (Delta) variant, CDC has updated the guidance for fully vaccinated people. CDC recommends universal indoor masking for all teachers, staff, students, and visitors to K-12 schools, regardless of vaccination status. Children should return to full-time in-person learning in the fall with layered prevention strategies in place.

Percent of Delivered First Vaccine Doses Administered by U.S. States and Territories

Percent of Delivered First Vaccine Doses Administered by U.S. States and Territories

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.

To help to understand vaccine administration CDC has created the map below to show the percentage of first doses of vaccines that have been administered in each jurisdiction from their supply. This information can be used to better understand how states are using their supply to initiate vaccination within their community.

Weekly Total Percentage of First Doses Administered Based on Jurisdiction Vaccine Supply

The majority of U.S. states and territories have administered at or above 76.3% of their first vaccine doses delivered.

Allocation

When a jurisdiction is allocated vaccine doses, the jurisdiction is 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.

Calculation

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%. Please see the footnote for more information.

Footnote: Denominator is defined as the 7-day average cumulative number of vaccine doses that were allocated as first doses, ordered, and delivered to the jurisdiction during July 13, 2021, to July 20, 2021 (as of 6am ET). Vaccine orders/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 this measure, the number of doses delivered designated as “first doses” is assumed to align with how the vaccine has been allocated nationally. Numerator is defined as the 7-day average cumulative number of vaccine doses administered as first doses and reported to CDC during July 16, 2021, to July 23, 2021 (as of 6am ET). A 3-day lag in the delivery totals was used to account for the time it takes from delivery to administration. It also gives the provider time to report the administration (required within 72 hours).
