On February 20, 2023, university leadership announced the following the following revisions to the vaccination policy:
- The existing COVID-19 vaccination requirement (receiving the primary series and one booster of COVID-19 vaccination) has been revised to apply only to UM-Ann Arbor students living in Michigan Housing.
- The policy no longer applies to students living off campus or employees outside of clinical settings. Some units will have their own policies in place, such as vaccinations required for healthcare or field placements.
- Michigan Medicine will maintain its current policy, and nothing is changing for its faculty, staff, and learners.
- Students living in UM-Ann Arbor Michigan Housing in fall 2023 will need to submit proof of receiving the bivalent omicron COVID-19 booster or have an approved medical or religious exemption by May 15.
- Also by May 15 these same students will need to submit proof of five routine childhood vaccinations or complete an attestation stating that they are not vaccinated and understand they may be subject to additional public health protocols should there be a public health need.
