Every Minnesota adult will be eligible for COVID-19 vaccine booster shots by the end of the week — even if the federal government hasn’t officially given the OK. State health officials made that decision based on what they're calling an “alarming surge” in COVID-19 cases.

Is that the right call? Will giving boosters to adults who are already vaccinated really help? Or would it be better to focus on the almost 40 percent of Minnesota adults who haven’t yet gotten a single shot?

Dr. Abinash Virk, an infectious disease specialist at Mayo Clinic in Rochester, answered questions about the booster shots from host Cathy Wurzer and Minnesota Now listeners.
