Third doses of vaccine being given by Mayo

A third dose of certain COVID-19 vaccines is now being given to qualifying patients in the Mayo Clinic health system. 

The doses currently are intended for patients 12 and older who have compromised immune systems, as a result of HIV infection or other causes. 

Anyone getting the third shot has to wait at least 28 days after a vaccination with the Moderna or Pfizer vaccine. 

Mayo says anyone who got the one-dose Johnson and Johnson vaccine does not need another shot at this time.      

Patients of Mayo who qualify for the third dose are being contacted on-line and by mail.
