Scheduling third COVID-19 shots for immunocompromised employees, patients now available

August 24, 2021  //  FOUND IN: Updates & Resources

Michigan Medicine is now offering the third dose of the COVID-19 mRNA vaccine to immunocompromised employees and patients. The CDC recommends patients with compromised immunity who have received two doses of the Pfizer or Moderna vaccine receive a third dose at least 28 days after the second dose.

Third dose of Pfizer vaccine now available for immunocompromised workforce members at Occupational Health Services (OHS)

OHS is now offering a third dose of the Pfizer COVID-19 vaccine for workforce members who are immunocompromised. This service is available for workforce members who previously received two doses of the Pfizer COVID-19 vaccine with the second dose being at least four weeks ago. Information about which health conditions qualify for a third dose of a COVID-19 vaccine can be found here:

Please note that workforce members who previously received the Moderna COVID-19 vaccine series should seek a third dose of the Moderna vaccine elsewhere. Information about additional COVID-19 vaccine resources at U-M Health and in the community is available at:

 There is currently no recommendation for additional doses of the Johnson & Johnson/Janssen vaccine.

Information about OHS location and COVID-19 vaccination hours can be found at: Workforce members should bring their ID badge and COVID-19 vaccine card (if available) to OHS when they present for vaccination.

Who should get a third dose of the COVID-19 vaccine?

The CDC recommends that anyone who has moderately to severely compromised immunity and received both doses of the Pfizer or Moderna vaccine get a third dose of the COVID-19 vaccine.  This includes people who have:

  • Been receiving active cancer treatment for tumors or cancers of the blood
  • Received an organ transplant and are taking medicine to suppress the immune system
  • Received a stem cell transplant within the last two years or are taking medicine to suppress the immune system
  • Moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome)
  • Advanced or untreated HIV infection
  • Active treatment with high-dose corticosteroids or other drugs that may suppress your immune response.

Patients will be asked to confirm that they have compromised immunity when scheduling a third dose appointment.  No additional documentation will be required, but patients will be asked to bring documentation of their first and second doses to the appointment.

Additional dose vaccines are not recommended for people who received the Johnson & Johnson/Janssen vaccine at this time. The FDA and CDC continue to evaluate data regarding the need for additional doses for other populations.

Can you get a different type of vaccine for your third dose than your previous COVID-19 vaccine doses?

The CDC recommends you receive the same mRNA vaccine for your third dose, if possible.  However, if the type of mRNA vaccine you received previously is not available, either mRNA vaccine can be administered for your third dose.

Michigan Medicine can give a vaccine to someone eligible for their second or third dose, even if the individual did not receive their first dose from Michigan Medicine. Proof of prior COVID-19 vaccination must be provided.

Third dose appointments can be scheduled online through the MyUofMHealth patient portal.

More information about who should get a third dose and how to schedule a third dose is available on our COVID-19 Vaccine FAQ page.
