The Sentinel-Record Covid Vaccinations in the U.S.*
* The table below lists the numbers of U.S. residents who have been vaccinated and who have received boosters, and compares those numbers by percentages of the population. Because vaccination totals may differ based upon the time of reporting, the Arkansas data includes information released by the Centers for Disease Control and Prevention (CDC) and the Arkansas Department of Health (ADH).
*Vaccination data reported on the CDC COVID Data Tracker may differ from data reported by states and territories for several reasons: Data may be updated on different schedules and reflect data “as of” different dates or times of day. There may be a delay between the time when a vaccination record appears in a state or jurisdictional system and when it is received by CDC.
Occasionally, there may be technical issues related to processing or transmission of data. When issues arise, CDC works closely with the states, territories, and federal entities to resolve the problem. CDC receives vaccine administration information from multiple sources, including jurisdictional immunization information systems, pharmacies, federal agencies receiving a direct vaccine allocation, and the Vaccine Administration Management System (VAMS), which supports temporary, mobile, or satellite clinics. Validation and business rules applied to prevent data duplication may cause data presented on the COVID Data Tracker to differ from what is in state immunization systems and dashboards. Every effort is made to reconcile doses administered that are reported through more than one system but, in certain circumstances, some vaccine doses administered could be counted more than once.
Health care providers report doses administered to federal, state, territorial, and local agencies up to 72 hours after administration. There may be additional lag for data to be transmitted from the federal, state, territorial, or local agency to CDC.
Doses are reported separately for federal entities. Doses administered by federal entities are not generally attributed to the jurisdictions in which they were administered. However, some federal sites may report such doses to both the jurisdiction and to the federal entity. Percentages display as “N/A” for federal entities because population-based rates are not applicable. Veterans Health Administration (VHA) totals include employees, veteran patients, and other federal partners vaccinated by VHA.
