In celebration of Global Accessibility Awareness Day, we invite you to join us May 19th from 3:00 – 4:00pm ET for a Twitter Chat at the intersection of accessibility, inclusion, and health. We will dive into some Accessibility 101, and explore how expanding participation in biomedical research can advance health equity. We will also share information about the All of Us Research Program, and explore its mission to make health research more inclusive to improve health outcomes.
