The clinic at Smart Financial Centre at Sugar Land is open to those only in Phase 1B, or people 65 years old and older. Appointments could only be made through Memorial Hermann's portal website.
According to the hospital, the appointment slots were from noon to 5:15 p.m. Those are no longer available now.
The clinic got underway earlier this week, with about 16,000 COVID-19 vaccines expected to be administered.
On Thursday, SkyEye captured a brisk line of cars and individuals outside of vehicles waiting to be vaccinated.
More information on the vaccinations at the Fort Bend County site can be found at Memorial Hermann's FAQ portal.
