Coronavirus clinical trial asks frontline workers to participate to test if tuberculosis vaccine could boost immune system
BCG could be widely available for use against COVID-19 in just six months because it has already been proven safe for other uses.
Currently, babies as young as one-day-old are given the BCG vaccine to protect them from TB. However, the effects of BCG wear off after 15-20 years.
There has not been a new and commercially available vaccination for tuberculosis in a century.
