Hospitals in Central Texas began vaccinating their staff against COVID-19 last week. For many, the vaccine represents an end in sight to what has been a grueling year for frontline health care workers. But it also comes as the state is experiencing a surge in cases. Tiffany Holder, a nurse in the emergency department of Dell Seton Medical Center, was one of the first people at the hospital to get vaccinated. She said she got a heads up a few weeks ago that she would be eligible for the first round. Around 5:45 p.m. Thursday, she and a coworker went to get their shots.
