When vaccines for COVID-19 started to become available in late 2020, demand for the shots far exceeded supply. Now, the inverse is true. About 35% of Texans are fully vaccinated, but the vaccines aren’t as highly sought-after as they were a few months ago. Instead, hospitals and pharmacies have had to throw out expired vaccines at an increasing rate, according to the Houston Chronicle. The shift in demand has led to a change in how the Texas Department of State Health Services, or DSHS, distributes vaccines to providers. Initially, because supply was limited, the department would take the lead and allocate the vaccines it received from the federal government to individual providers. But now it leaves it to the providers to request what they need.
