COVID-19 vaccines are being distributed across the U.S. and its territories. Three vaccines – one made by Pfizer-BioNTech, one from Moderna and another from Johnson & Johnson – have been authorized for emergency use and are part of the widespread distribution process. The first shots were given Dec. 14.
When will everyone be vaccinated?
Anthony Fauci, President Joe Biden’s chief medical adviser, said he thinks the share of people who need to be vaccinated for the USA to reach herd immunity is “somewhere between 70 to 90 percent.” At the current pace of vaccine administration, it will take a few more months to reach that range.
Children younger than 18 years old make up about 22% of the U.S. population, but no vaccines have been authorized for children under 16. Of the three vaccines authorized for use in the USA, the Pfizer vaccine is the only one available for 16- and 17-year-olds.
Map: How many people have been vaccinated in each state
States prioritized at-risk populations to be vaccinated first, including medical staff, people in nursing homes or other long-term care facilities, essential workers, the elderly and people with medical conditions that put them at greater risk of becoming seriously ill with COVID-19.
Vaccine eligibility is now expanding. On April 6, Biden announced that all adults in the U.S. will be eligible by April 19. The White House said there will be enough vaccine to cover every American adult by the end of May, although it will take longer to administer those shots.
Map: How many people have been vaccinated in each county
County-level data is most accurate in states that report county of residence to the CDC for a high percentage of people vaccinated. In states that report the county of residence at a lower rate, the vaccination rate for counties may appear to be lower than it actually is.
For this reason, data is not shown for states that included a county of residence for less than 80% of people vaccinated there. Some states, such as Texas and Hawaii, do not report county-level information to the CDC.
Data: Percent of people given a COVID-19 vaccine and how many shots are left
More than 30.8 million in the U.S. have tested positive for COVID-19 since January 2020, and more than 556,000 have died from the virus. More than 100 million people have received at least one dose of vaccine.
How many people have been given vaccines distributed and administered by federal agencies
Some federal agencies manage their own distribution and vaccination processes outside state governments. The statistics from these agencies are included in state data.
Chart: How many shots from each vaccine manufacturer have been administered?
The Pfizer-BioNTech and Moderna vaccines require two doses, and the Johnson & Johnson vaccine requires only one for the recipient to be fully vaccinated. For the Pfizer-BioNTech and Moderna vaccines, a second shot should be administered about three or four weeks after the first, depending on which of the vaccines was given.
Populations used for U.S. state, District of Columbia and Puerto Rico calculations are from the U.S. Census Bureau’s 2019 state population estimates. Populations used for other territory and associated island state calculations are from the World Bank.
The share of distributed doses used in each state or territory is calculated by dividing the number of doses administered in that state or territory by the number of doses distributed to that state or territory. The percent of people vaccinated in each state, territory or county is calculated by dividing the number of residents of that state, territory or county who have been vaccinated by the population of that state, territory or county.
Because of reporting delays and other factors, the CDC data above may differ from that of states’ and territories’ own reports and dashboards. For more information, see the footnotes on the CDC’s website.

On Feb. 19 and 20, the CDC reported an incorrect number of national doses delivered because deliveries to federal entities were inadvertently counted twice. On March 4, the CDC removed 98,475 doses from Maryland’s delivered doses total because it was determined that the doses, though delivered to facilities in the state, were not intended for vaccinating persons in or around Maryland. On March 5, the CDC removed 239,900 doses from Pennsylvania’s delivered doses total and 91,950 doses from Virginia’s delivered dose total because it was determined that the doses, though delivered to federal facilities in those states, were not intended for vaccinating persons living there. Starting Feb. 20, Connecticut’s first doses were slightly overcounted and second doses slightly undercounted. The CDC corrected Connecticut’s dose count errors by March 13.
Corrections & Clarifications: Because of a change in CDC reporting, from Jan. 15 to 16 this page displayed the number of total vaccine doses administered as a share of population, instead of the number of first doses administered. We have corrected the error.
From Feb. 22 to 25, a footnote incorrectly described the measure used to calculate the percent of people vaccinated in each state or territory. We have corrected the error.
