About the chart: The chart below shows Dose 1 vaccination progress at Michigan Medicine based on the approximate number of eligible Michigan Medicine and University of Michigan faculty, staff and patients within each phase. The numbers are approximate because they are continuously changing due to geographical location, affiliation with other health providers or employers, and other factors.

Phases of distribution: We are currently vaccinating those who fall into Phases 1a and 1b. See "Phases of Vaccine Distribution" below for more information about about each phase.

Phases of Vaccine Distribution

Michigan Medicine is administering the COVID-19 vaccine based on guidance from the Michigan Department of Health and Human Services (MDHHS). MDHHS follows Centers for Disease Control (CDC) recommendations based on input from the Advisory Committee on Immunization Practices (ACIP), a CDC advisory committee made up of medical and public health experts who develop recommendations on the use of vaccines in the United States.The CDC and ACIP have defined populations for different vaccination phases:

Phase 1A

Includes paid and unpaid persons serving in health care settings who have direct or indirect exposure to patients or infectious materials and are unable to work from home, as well as residents of long-term care facilities. In accordance with MDHHS guidance to support critical health infrastructure, phase 1A also was expanded to include all Michigan Medicine employees.

Phase 1B

Includes people age 65 and older, as well as frontline essential workers including first responders, Pre K-12 education, food and agriculture, manufacturing, corrections, postal service, public transit, and grocery store workers.

Phase 1C

Includes those at high risk for severe COVID-19 illness due to underlying medical conditions such as COPD, hypertension, chronic kidney disease, heart disease, diabetes, obesity or other conditions that puts them at high risk of negative COVID-19 outcome. Phase 1C also includes essential workers in transportation and logistics, food service, construction, finance, IT and communication, energy, media, legal, public safety (engineers, water and wastewater).

Phase 2

A mass vaccination campaign for all people age 16 and older.
