St. Paul (LEARFIELD)  —  State health officials are hosting two temporary COVID-19 vaccination events this week in southwestern Minnesota.   The clinics are aimed at workers in food processing and agriculture and other eligible Minnesotans.  The doses are being administered at the MERIT Center in Marshall and the Worthington Events Center.    Marshall and Worthington join the seven large-scale sites in the state’s Community Vaccination Program. Governor Tim Walz says these new locations provide even more opportunities for people to get their shots.
