The All of Us Research Program is a nationwide NIH initiative aiming to build one of the largest and most diverse health databases in history by enrolling one million or more people across the U.S. Its purpose is to accelerate precision medicine—research that tailors prevention and treatment to each individual. Participants share surveys, electronic health records, physical measurements, and biological samples, creating a rich dataset and extensive health information. Gundersen Foundation's Dr. Todd Mahr discussed the program on W-I-Z-M's LaCrosseTalk.
