COVID-19 mass vaccination site opening this week at NRG Park

The FEMA-supported COVID-19 mass vaccination site is opening this week at NRG Park.

A COVID-19 vaccine clinic is held by appointment only in a parking lot at NRG Park in Houston, Texas, on January 14, 2021.

Houston and Harris County officials are working to make sure the area’s most vulnerable populations and underserved communities are prioritized.

According to a release, the site will fully-vaccinate approximately 126,000 people by serving 6,000 per day seven days per week for three weeks before transitioning to second doses for three weeks.

Both departments will use their waitlists to schedule appointments for the drive-thru site.

Houston Health Department
The Houston Health Department’s strategy for the NRG Park site will utilize its Area Agency Aging waitlist with the following prioritization criteria:
•    Priority 1 – People age 65 and older who live in a high-risk zip code,
•    Priority 2 – People age 65 years and older,
•    Priority 3 – People age 60-64 with underlying medical conditions who live in high-risk zip codes, and
•    Priority 4 – People age 60-64 with underlying medical conditions.

Houston’s high-risk zip codes are geographic areas with people more vulnerable to severe COVID-19 illness as identified by positivity rate, underlying health condition, economic, and social data.

The department’s waitlist remains open for people age 65 and older and people age 60 and older with chronic health conditions. Those who qualify may call the department’s Area Agency on Aging at 832-393-4301 to leave a voicemail with their name and phone number. Calls will be returned for screening and scheduling.

An online registration portal for those who meet the criteria opens Tuesday at

In addition to the FEMA site, HHD will continue to schedule vaccinations at Bayou City Event Center, Delmar Stadium, its health centers and multi-service center, and partner federally-qualified health centers and pharmacies.

Harris County will utilize its current vaccination waitlist: or individuals can call 832-927-8787 (If registering online do not use Internet Explorer or Microsoft Edge).

In addition to the age cohorts, HCPH will be prioritizing areas where there have been COVID health disparities (using the CDC’s social vulnerability index and where data shows there are 1) increased COVID cases or deaths and/or COVID undertesting).
