The CDC is working with jurisdictions to provide more information on the demographic characteristics of vaccinated people.
These demographic data are representative of the geographic areas that contribute data and may differ according to the population prioritized in each jurisdiction’s vaccination phase. Therefore, these data may not be generalizable to the entire US population. The percentages shown in the chart below represent the percentage of people vaccinated in each age group.
Data will be updated as soon as it is reviewed and verified, often before 8:00 pm ET each day. However, daily updates may take longer if there are delays in data reporting.
Data on vaccine doses administered include data received by the CDC at 6:00 AM ET on the reporting day. Vaccination data on the CDC COVID Data Tracker is updated daily (including weekends) between 1:30 PM and 8:00 PM ET. Updates will be made the following day when reporting coincides with a federal holiday.
This data represents the subset of individuals in the jurisdictions (states, territories, and local entities) for which data has been reported. Demographic data includes people vaccinated through all parts of the program, including those vaccinated through pharmacies, the Federal Pharmaceutical Partnership Program for Long-Term Care (LTC), and federal entities.▓
Reported demographic data have varying degrees of data loss and cannot be generalized to the entire population of individuals who have received COVID-19 vaccination.
Missing data may be affected by inconsistent collection of information at the time of vaccination, differences in jurisdictional electronic data programs, and some jurisdictional policies or laws that do not allow demographic data to be reported.
Vaccinations by age group at the US level, visualized in two pictures:
Percentage by age group among people who received at least one dose of vaccine and
Percentage by age group among people who were fully vaccinated.
All reported numbers may change over time as historical data is reported to the CDC.
* Texas does not report age-specific dose number information to the CDC, so data for Texas is not represented in this figure.
Doses reported as given before the start of the national vaccination program on 12/14/2020 are not included in the figures but are included in the cumulative total of the total doses given in the CDC COVID Tracker.
Definition:
People who received at least one dose ** (previously “received 1 or more doses”) represent the total number of people who have received at least one dose of the vaccine.
Fully vaccinated people ** represent the number of people who received a second dose of a two-dose vaccine or a single-dose vaccine.
For reporting on the CDC COVID Data Tracer, the CDC counts people as “fully vaccinated” if they receive two doses on different days (regardless of time interval) of a two-dose mRNA series or receive a single dose of vaccine. Clinical Considerations While the current CDC is more specific than a COVID data tracker in two ways:
First, according to interim guidelines, the second dose of Pfizer-BioNTech and Moderna vaccines should be given as close as possible to the recommended intervals, but not earlier than the recommended (i.e., 3 weeks [Pfizer-BioNTech] or 1 month [Moderna]). However, a second dose given within a grace period of 4 days earlier than the recommended date for a second dose is still considered valid. If you cannot follow the recommended interval and delay in vaccination cannot be avoided, the second dose of Pfizer-BioNTech and Moderna COVID-19 vaccines can be given up to 6 weeks (42 days) after the first dose. At present, only limited data is available on the efficacy of the COVID-19 mRNA vaccine provided outside of this window.
Second, to ensure sufficient time for the immune response to occur, a person is considered to be fully vaccinated = 2 weeks after completing a two-dose mRNA series or a single dose of the Janssen Johnson & Johnson vaccine.
** The number of people who received at least one dose of vaccine and the number of people fully vaccinated was determined based on information reported to the CDC regarding dose number, vaccine manufacturer, date of administration, recipient ID, and date of delivery. Because the methods used to determine dosage amounts need to be applied in a variety of jurisdictions with different reporting practices, estimates of CDC dose counts may differ from those reported by jurisdictions and federal entities.
To calculate the national population estimate, the CDC uses, as a denominator, a combination of:
2019 National Census Population Estimates from the US Census Bureau Annual Estimates of Resident Population for the United States (including the District of Columbia [DC]) and Puerto Rico
(https: //www2.census….-2019/counties/)
and the 2018 CIA World Factbook for US territories and free-associated states (American Samoa, Federated States of Micronesia, Guam, Commonwealth of Northern Mariana Islands, Republic of Palau, Republic of the Marshall Islands, and US Virgin Islands).
To estimate the population 18+ and 65+ for the US region, the CDC assumes that the proportion of people 18 years and over and 65 and over in the region equals the total of the 50 states, DC, and Puerto Rico (78 % and 17%, respectively).
Emergency Use Authorization has been granted for use of the Pfizer-BioNTech vaccine among people aged 16 years and over and for use of Moderna vaccine and Johnson & Johnson Janssen vaccine (J & J / Janssen) among persons aged 18 years and over. on. Therefore, vaccine use is limited to those under 18 years of age.
