We are a group of citizen scientists motivated to action by the suffering caused by the SARS-CoV-2 pandemic. We have a range of backgrounds and professions, but many of us are trained scientists and engineers. RaDVaC was launched by Preston Estep, Don Wang, Alex Hoekstra, and Ranjan Ahuja, who were soon joined by a growing contingent of friends and colleagues. This expanding core group met through our associations with Harvard Medical School and HMS Professor George Church. Our project was launched in the Boston area but is expanding steadily across the U.S. and throughout the world.

RaDVaC is a 501(c)(3) non-profit, not a commercial organization. We have filed no patent applications or protections of intellectual property on the vaccine work described on this site, and are sharing our collective works and inventions under open licenses (CC BY 4.0 and OCL-P v1.1), and are part of the Open COVID Pledge. Existing public health, commercial, and regulatory infrastructures have thus far failed to provide a vaccine to protect humanity–especially our most vulnerable–against the pandemic. Therefore, we have drawn on decades of scientific literature describing proven vaccine designs to develop, produce, and self-administer an intranasally delivered vaccine, and we release this information as a necessary act of compassion.
