The data is updated on weekdays at around 4:00 pm ET. It contains updated vaccination information as of 9:00 am on weekdays.
Note: CDC doesn't release this data over the weekend. Thus, you may notice a huge bump in vaccinations on Mondays and Tuesdays.
Doses distributed are cumulative counts of COVID-19 vaccine doses recorded as shipped in CDC’s Vaccine Tracking System (VTrckS) since December 13, 2020. Doses distributed to a state or territory include those shipped to the jurisdiction and to pharmacies in the jurisdiction through the Federal Pharmacy Partnership for Long-Term Care Program.
Total doses administered are cumulative counts of individual COVID-19 vaccine doses administered as reported to CDC by state, territorial, and local public health agencies and federal entities since December 14, 2020.
People receiving 1 or more doses and people receiving 2 doses were assigned based on information reported to CDC by state, territorial, and local public health agencies and federal entities on dose number, administration date, recipient ID, and date of submission. Because the method used to determine dose numbers needs to be applied across multiple jurisdictions with different reporting practices, CDC’s dose number estimates may differ from those reported by jurisdictions and federal entities. A dose number was determined for nearly all reported doses administered but, because there are some missing data for dose number, the sum of people receiving 1 or more doses and people receiving 2 doses will not exactly equal the total doses administered.
Long-term care facility (LTCF) data are specific to the Federal Pharmacy Partnership for Long-Term Care (LTC) Program and primarily include skilled nursing and assisted living facilities. Doses administered refers to vaccine administered to LTCF residents and staff, as reported to CDC by the pharmacy partners participating in the program.These data do not include doses administered to LTCF residents and staff outside the Federal Pharmacy Partnership for Long-Term Care Program. Vaccine administration through the federal program launched nationally on December 21 for Pfizer-BioNTech vaccine and on December 28 for Moderna vaccine. As of January 4, 2021, a total of 56 jurisdictions have started the program. Program start dates varied based on the jurisdiction.
Rates per 100,000 population use the U.S. Census Bureau 2019 American Community Survey 1-year population estimates. 2018 population estimates are used for American Samoa, Federated States of Micronesia, Guam, Northern Mariana Islands, Palau, Republic of Marshall Islands, and United States Virgin Islands. Differences in the relative size of populations targeted for vaccination across jurisdictions should be considered when comparing population-based rates across jurisdictions.
