The U.S. is in better shape approaching its second Thanksgiving of the pandemic, thanks to the vaccine.

That leaves millions without a shot in the arm. Hospitals in the cold Upper Midwest, especially Michigan and Minnesota, are filled with COVID-19 patients who are mostly unvaccinated. Dr. Rochelle Walensky of the Centers for Disease Control and Prevention says vaccines make this fall holiday much different.
