KUT The director of Austin Public Health says the department needs to change its process to reach and vaccinate more people in Austin and Travis County after nearly 3 out of 4 first-dose coronavirus vaccine appointments released Monday went unfilled. "In conversations with some of my colleagues across the state of Texas, a lot of us are getting to a point where we're going to have to pivot and change strategies," Stephanie Hayden-Howard told a joint session of the Austin City Council and Travis County Commissioners Court on Tuesday. "Because now we're at a point where there is more vaccine that is readily available in our community. So we must be strategic and start [making] those changes."
