More than 500,000 COVID-19 vaccines have been administered in Williamson County as of May 21, according to Texas Health and Human Services data.

As of noon May 21, 502,435 doses have been given, it said.

“Our team did an amazing job if you think about putting 500,000 doses into people,” Williamson County Judge Bill Gravell said. “We didn't know how to do mass vaccinations, and much of the dream and planning came from around this table and the good leaders that work in Williamson County.”

Approximately 73.5% of Williamson County residents age 65 and older have been fully vaccinated, while 87.58% of the same group has received at least one dose, according to state numbers.

Approximately 46.59% of the population age 12 and older are fully vaccinated with 59.36% receiving at least one dose, it said.

Between May 17-20, about 6,000 doses had been administered, the fewest number of doses since early February. The peak number of doses administered in the county was in early April with nearly 56,000 administered, it said.

Williamson County closed its three mass vaccination sites in early May, citing a decrease in demand. Vaccines are still available at pharmacies, clinics and other local health care providers.

“My best day as county judge was on ... the opening night of the Round Rock Express,” Gravell said. “I was sitting there with some friends, you know, watching the fireworks, and I looked down at all the folks, and I realized, we survived. We did it together.”
