“When will we be rid of COVID-19?” isn’t a tough question to answer. A vaccine is one way to achieve herd immunity, the point at which the virus is statistically doomed, and there are over 150 candidates currently being tested for the spot. But it’s not enough to just be safe and effective; a successful vaccine must also be distributed to large swaths of the world’s population to provide large-scale immunity. 

A group of self-described citizen scientists have thrown their hats into the vaccine race with a candidate that has not been formally evaluated for safety, efficacy, or scalability. MIT Technology Review first reported that this group, called the Rapid Deployment Vaccine Collaborative (Radvac), has ties to Harvard Medical School researchers, and over 20 members of it have self-administered the intranasal vaccine.
