Texas Vaccine Institute

What Texas Vaccine Institute does

Texas Vaccine Institute (TVI) is a privately held Texas corporation founded in June 2000 by Pablo De Angulo, M.D., and headquartered at 21811 Katy Freeway, Suite D-102, Katy, TX. The company provides on-site vaccination services — primarily influenza vaccines, plus childhood and travel immunizations — deploying licensed nurses and medical assistants directly to client locations including K-12 school districts, private companies, churches, and health fairs across the Greater Houston area. TVI also operates a walk-in clinic at its Katy headquarters, open Monday through Friday and Saturday mornings with no appointment required.

The company is fundamentally a service-based, logistics-driven healthcare provider rather than a technology platform; there is no proprietary software, AI, or digital infrastructure described in available materials. Its core differentiator is a mobile distribution model that pre-orders vaccine inventory at scale each season to guarantee supply, supported by 25+ years of operating history, 300,000+ cumulative vaccinations administered, and consecutive-year relationships with major Houston-area Independent School Districts including Houston ISD, Alief ISD, Aldine ISD, Katy ISD, Spring Branch ISD, and Lamar Consolidated ISD. The website is presented bilingually in English and Spanish, signaling outreach to Hispanic communities within the existing footprint.

TVI generates revenue primarily through per-vaccination and per-clinic service fees billed to enterprise clients (school districts and corporate accounts such as CGG Veritas), supplemented by walk-in retail vaccinations. Pricing is quote-based and described as competitive and affordable, with at least one customer testimonial indicating under $10 per vaccine. Demand generation is driven by referral and word-of-mouth within Houston-area school district and corporate networks, with no evidence of active digital marketing. The company is founder-owned and operated with no disclosed venture capital, private equity, or institutional investor involvement, and no subsidiaries, acquisitions, or funding rounds are recorded.
