Lexington may take longer to finish 1st phase of COVID-19 vaccinations. Here's why Jeremy Chisenhall, Lexington Herald-Leader Jan. 7—State leaders have recently criticized slow vaccine rollout in Kentucky, but Fayette County officials maintain that they're getting the shots into people's arms as quickly as possible. Even so, Lexington may fall behind other counties across the state in trying to get through the initial stage because Fayette County has over 20,000 health care workers, according to the Lexington-Fayette County Health Department. That's over 6 percent of the local population. "We're still very early in Phase 1A in Lexington because of the vast number of people who qualify as 1A," health department spokesman Kevin Hall said. "The number of health care workers in Lexington is larger than the population of several Kentucky counties."
