A health care worker administers a COVID-19 vaccine at Dell Medical School. UT’s Dell Medical School (along with UT Health) and Austin Public Health are reporting issues getting people signed up to be vaccinated against COVID-19. Both organizations were designated by the state as "hub" providers. The state created the hub model so larger organizations — a couple dozen across Texas — could vaccinate a lot of people at once. APH and UT were getting thousands of vaccines shipped every week, while other providers — like pharmacies and stores — received much fewer. But lately, both groups say there has been a decrease in demand.
