CHRISTUS Health launched virtual assistant to increase vaccinations across four states

September 11, 2023

Fabric’s vaccine experience was deployed on the CHRISTUS website in three weeks, allowing patients to self-screen from any desktop, smartphone, tablet, or web-browsing device. The endpoints were configured to reinforce CHRISTUS’ state specific vaccination plans and resources. CHRISTUS chose Fabric as their partner for fast deployment, flexibility to add product capabilities as needed, and the ability to handle thousands of requests each second. Fabric’s vaccine offering helped CHRISTUS meet patient demand for answers and appointment scheduling to receive the vaccine.

CHRISTUS partnered with Fabric to expand the AI-assistant on its website to screen for vaccine eligibility. Knowing there would be a high demand for appointments, Fabric configured the system to make sure their vaccine assistant could successfully handle over 5,000 hits per second. By implementing these load-bearing protocols, CHRISTUS avoided website crashes. The addition of a hidden, single-use URL prevented link sharing. Fabric also added enhanced safety measures to mitigate the likelihood of the system being breached.

Due to the overwhelming success of the initial go-live, CHRISTUS requested Fabric to be their front-end solution, as the health system partnered with the State of Texas and local counties to manage vaccination sites in their region.Replicating the initial work, Fabric helped CHRISTUS launch a second site to accommodate patient demand.
