If a vaccine is approved this week, Duke Health officials said they will be prepared to give out doses as early as next week to frontline healthcare workers.
Right now, Duke is working with the state to determine how much vaccine they get and then who will get it first inside the hospital.
"We can truly see this as the next chapter of this pandemic," said Mitch Babb, chief operating officer of Duke Regional. "We've been through a lot over the past year as a country and as healthcare workers. To truly see this as a glimmer of light above the horizon for our healthcare workers, for our hospitals and more important for the broader community."
Duke Health has 114 COVID-19 patients across its three hospitals currently.
