The First Tennessee Development District Foundation, which serves Northeast Tennessee, received a $541,700 grant on Wednesday from BlueCross BlueShield of Tennessee Foundation, which will fund three mobile vaccination vans to help get vaccine into the region’s more rural areas. The grant was awarded to the FTDD based on its emphasis on a public service campaign encouraging people to get vaccinated and its plan to mobilize healthcare workers to vaccinate people in areas where a mass vaccination site isn’t possible in all eight of the region’s counties.
