Arkansas clinics say the supply of the Covid-19 vaccine is outweighing the demand. Author: Micah Wilson Updated: 6:28 PM CDT April 1, 2021 Clinics in both the River Valley and Northwest Arkansas say they have more doses of the vaccine than people signing up to receive it. “So, we have 2,500 doses available. At the beginning of the morning, we had about 1,200 of those appointments filled and we are getting multiple walk-ins. So, if we can get all of those 2,500 doses in arms today. If not, we will use them tomorrow,” said Lindsey Sabatini, Interim Assistant Director of University of Arkansas’ Eleanor School of Nursing.
