On Mar. 10, 2021, the U.S. Department of Defense (DOD) announced that it had identified additional personnel authorized to support the Federal Emergency Management Agency (FEMA) in administering COVID-19 vaccinations at community vaccination centers around the country.

FEMA has asked the Defense Department for as many as 50 Type 1 teams to support community vaccination centers, as well as 50 Type 2 teams. A Type 1 team is made up of 222 service members, and can administer about 6,000 vaccinations a day, while a Type 2 team is made up of 139 service members and can administer about 3,000 vaccinations a day. The department is also staffing 25-person teams as well in some locations.

To date, about 6,235 active duty service members have been identified by the Defense Department to support COVID-19 vaccination centers, though not all of those personnel have deployed yet as part of a team.
