WHEELING, W.Va. — The day had finally arrived. After nearly a year in lockdown for the residents of Good Shepherd Nursing Home — eating meals in their rooms, playing bingo over their television sets and isolating themselves almost entirely from the outside world — their coronavirus vaccinations were finished and the hallways were slowly beginning to reawaken.In a first, tentative glimpse at what the other side of the pandemic might look like, Betty Lou Leech, 97, arrived to the dining room early, a mask on her face, her hair freshly curled. “I’m too excited to eat,” she said, sitting at her favorite table once again.
