Editor's note: This story was updated at 6:08 p.m. Jan. 19 to reflect current vaccine appointment availability. Neither Galveston County hub is offering new vaccine appointments to residents as of the evening of Jan. 19.

Walter Hall Park in League City has been closed to the public as the county prepares the park to become a potential mass COVID-19 vaccination site, according to Galveston County social media posts.

The park, located at 807 Hwy. 3 N., closed starting Jan. 19 and will remain closed for the next 60-90 days, according to posts on Facebook and Twitter. The county has 19 other parks, according to its website.

If it becomes a hub, it would join two others currently established in the county: One is at the University of Texas Medical Branch hospital in Galveston, and the other hub is at the Galveston County Health District, according to the Texas Department of State Health Services.

The health district opened more appointment slots Jan. 19 to vaccinate individuals ages 65 and older, according to a media release from the League City Regional Chamber of Commerce. All appointments to claim one of the additional 1,000 doses sent to GCHD were filled the same day, according to a health district Facebook post.

Any Texas resident interested in receiving email updates on vaccine rollout can sign up on the health district's website. About 3,500 people have been fully vaccinated in the county, with more than 18,000 having received at least one dose, per DSHS data.

The hospital said it will receive 4,000 doses the week of Jan. 18, which will be distributed to high-risk individuals who had appointments canceled due to lack of supply, ABC 13 reported. The hospital will contact those individuals with canceled appointments directly. The shipment was allotted before the hospital had been designated as a hub.

"We've been asked to be able to vaccinate up to 2,000 people per day, and I think we're at that capacity right now,” Philip Keiser, Galveston County local health authority, told ABC 13 in regard to the UTMB hub’s activity. “We've also been told to expect to be able to vaccinate up to 5,000 people per site, per day, and that is going to take some time to get to that capacity, but we think we can do it.”

Keiser told ABC 13 the hospital expects to use up the vaccines in three to four days once they arrive the week of Jan. 18. During the week of Jan. 11, the hospital had to cancel 6,000 first dose appointments and ran out of vaccines by Jan. 13 after not receiving another shipment at the start of the week, ABC 13 reported.

The hospital will resume scheduling new appointments as soon as it receives sufficient vaccines for first doses, and it will communicate about vaccine hub activities including location and registration process once those arrangements have been finalized, according to UTMB’s COVID-19 Vaccine Information page.

People with appointments for a second dose are still scheduled to get them, hospital officials told ABC 13.

"We want to make sure that people we already promised the vaccine [to], that they get the vaccine," Keiser told ABC 13.
