Williamson County will begin vaccinating individuals who qualify under Phase 1C, as determined by Texas Department of State Health Services, on March 15, according to a news release.

Phase 1C includes anyone between the ages of 50-64. DSHS reported that people in this age bracket are the next most vulnerable group in the population and could suffer serious to life-threatening effects when infected with COVID-19, the release said.

Individuals who qualify may sign up for the waitlist to receive the COVID-19 vaccine at www.wilco.org.

To date, 144,669 doses have been administered to Williamson County residents, and 42,995 of those residents have been fully vaccinated, according to data provided by DSHS.

Williamson County has approximately 13,500 people on the waitlist that are in Phase 1B with approximately 3,600 of that group who are over 65. Williamson County’s vaccine providers, Family Hospital Systems and Curative, will begin sending emails for vaccination appointments to people in Phase 1C as the vaccine supply from the state allows.

Williamson County hub partners are operating three drive-thru site locations at Kelly Reeves Athletic Complex, the Georgetown ISD Athletic Complex and Dell Diamond in Round Rock, which opened March 12. Individuals should not show up to a site unless they have an appointment, officials said.
