Tom Murphy January 31, 2021 - 6:19 AM Frustration is building over the pace of COVID-19 vaccinations at long-term care sites, where some homes still await first shots while fending off a virus that can devastate their residents. The major drugstore chains tasked with giving shots in these places are far along in vaccinating nursing home residents and staff. But some other types of group residences won't receive first doses until mid-February or later, despite being among the top priorities for shots. CVS and Walgreens have started a massive vaccination push in nearly all states, and they say they are proceeding on schedule. But resident advocates and experts are anxious about delays in delivering vaccines that have been available for more than a month.
