Updated vaccine boosters for COVID-19 became available last week in Minnesota. 

The new versions of the vaccine from Pfizer-BioNTech and Moderna protect against two of the most common versions of the virus, Omicron subvariants BA. 4 and BA. 5. 

White House COVID-19 advisors say the public should plan to get a new COVID-19 shot every year to protect against new versions, much like an annual flu shot. 

MPR News host Angela Davis talks with two infectious disease doctors about what you need to know about the new COVID-19 vaccine boosters and how to navigate the fall virus season. 


  • Dr. Jill Foster is a pediatric infectious disease physician with M Health Fairview and director of the Division of Pediatric Infectious Diseases at the University of Minnesota Medical School. 

  • Dr. Abinash Virk is an infectious disease physician with the Mayo Clinic and a professor at the Medical School in the Division of Infectious Diseases.
