(Golden Valley, MN)  —  A new warning is out about a possible COVID-19 resurgence.  A vaccinologist at Mayo Clinic is predicting a surge in Minnesota like those recently seen in the UK and starting to arrive in New York and Washington DC.  Dr. Gregory Poland says the pandemic isn’t over and mutations of the virus keep coming.  The FDA approved a second Pfizer or Moderna booster last month for those over 50 and immunocompromised people 12 and up.
