While many Valley residents have received the COVID-19 vaccine, Centex Studies, a clinical research company in McAllen said there's still work to be done in the trial stage.

Site Director of Centex Studies Joanna Mahoney said the research company will be conducting and monitoring COVID-19 vaccination trials from AstraZeneca, Johnson & Johnson and Novavax. 

Mahoney said they need people 18 or older with a stable medical condition, who are interested in volunteering. 

The way it works:

Participants will receive doses of a placebo or an actual vaccine. After each visit the participants will remain in close contact with Centex, while also have 24/7 physician care, dedicated to any and all medical needs.
