Clinical Trial Summary

Bacille Calmette-Guerin (BCG) is a live attenuated vaccine administered for prevention of tuberculosis. Recently, several groups have hypothesized that BCG may "train" the immune system to respond to a variety of unrelated infections, including viruses and in particular the coronavirus responsible for COVID-19. Trials are currently being conducted in Australia, Netherlands, Germany and the United Kingdom to evaluate its effectiveness. Front line workers includes members of municipal and provincial police services, emergency medical personnel, firefighters, public transport employees, health service workers and food manufacturing employees. They are at high risk of infection from COVID-19, with potentially high infection rate. The investigators propose an interventional trial to evaluate the effectiveness of BCG vaccination to prevent COVID-19 infection and reduce its severity in front-line employees in Ontario.
