A push to reach herd immunity by getting vaccines to the hesitant Convincing the skeptical to get the COVID-19 vaccine is a long and precarious process. David Ross, the administrator at Hillsborough County Nursing Home, has been chipping away at hesitancy among staff and some residents since January. “It’s a delicate balance,” he said. “We don’t want people to feel — I don’t want to use the word harassed — but harangued at work. They made a personal decision. You know, I’m trying to be respectful of that.” But Ross is also acutely aware of how quickly one case of COVID-19 can spiral into disaster. The virus killed more people at his nursing home than any other similar facility in the state — across two separate outbreaks, there were 254 infections among staff members and 52 people died.
