WILLIAMSON COUNTY, Texas (KXAN) — Now that demand for COVID-19 vaccines have leveled out, Williamson County said it’s ending the centralized waitlist for vaccinations — and closing its mass vaccination sites.

“As of today, in Williamson County, the total doses administered is 404,773 doses,” said County Judge Bill Gravell at a Monday briefing at Dell Diamond in Round Rock.

Countywide, 33.43% of residents have been fully vaccinated, while 51.28% have received a first dose. As of Monday, 61,299 residents age 65 and older have been vaccinated, or 83.7%. Of this age group, Gravell said the county has given second doses to 47,935 residents, or 65.4%.

Over the past week, the county administered 20,110 first doses.

Due to dwindling numbers of new vaccinations, Gravell previously said Williamson County mass vaccination sites would likely close down by Memorial Day — but announced Monday they will now close officially.

Closure of the sites will also open up space at Dell Diamond — currently a mass vaccination site — for the Round Rock Express’ opening day in early May.

“I just want to say this to the citizens of Williamson County: you have been patient for the last year… and I want to say thank you for your patience,” said Gravell. “And I also want to say to our community: you’ve been faithful in the last four months, as we prioritized our first responders and our most fragile community, and you allowed them to get vaccinated before you.”

There are currently 25 vaccine providers in the county offering more than 20,010 first shots, the county reports. Residents will now be schedule a shot directly with a provider of their choice.

Gravell also revealed Williamson County will no longer host briefings on COVID-19, while also adding that while the pandemic is not over and vaccinations are still needed, “it’s time to open America.”
