As the COVID-19 pandemic ravages the U.S., vaccines have begun to be distributed across the country and its territories. Two vaccines, one made by Pfizer-BioNTech and another from Moderna, have been authorized for emergency use and are part of the widespread distribution process. The first shots were given Dec. 14.
Each of the vaccines require two doses. A second shot should be administered about three or four weeks after the first, depending on which vaccine was given.
Map: How many people have been vaccinated in each state
More than 25 million in the U.S. have been sick with COVID-19 since January 2020, and more than 400,000 have died from the virus. More coronavirus cases have been recorded this winter than at any previous period of the pandemic. Despite this, many states are struggling to administer vaccines at the same rate the vaccines are delivered.
Map: How quickly states are administering their vaccines
Because of a lag in reporting, the share of vaccines that have been given may be larger than it seems. However, the process has gone more slowly than officials initially hoped.
President Joe Biden has said he hoped to get 100 million shots administered within his first 100 days in office. Between Dec. 14, when vaccinations started, and Jan. 20, when Biden took office, about 16.5 million shots were administered.
Data: Percent of people given a COVID-19 vaccine and how many shots are left
Anyone age 16 or older can receive the Pfizer-BioNTech vaccine, but the Moderna vaccine is authorized only for adults. States prioritize 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.
Some federal agencies manage their own distribution and vaccination processes outside state governments. These numbers are not usually included in state tallies, although some federal sites may still report their data to states.
How many people have been given vaccines distributed and administered by federal agencies
Populations used for U.S. state, D.C., and Puerto Rico calculations are from the U.S. Census Bureau’s 2019 state population estimates. Populations used for other territories and associated island state calculations are from the World Bank.

Corrections & Clarifications: Due to a change in CDC reporting, from Jan. 15 to Jan. 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.
