New research supports the use of the tuberculosis vaccine Bacillus Calmette-Guerin (BCG) as a tool in the fight against the novel coronavirus COVID-19.
According to CNN researchers found that countries in which many people have been given the vaccine were less likely to die from COVID-19.
That doesn't mean that BCG somehow reduces the risk of severe illness from a coronavirus infection.
However, it aligns with other research indicating BCG can boost people's immunity in general, and perhaps help against the virus.
The World Health Organization cautions against using vaccine for coronavirus until more is known. Still, teams around the world are looking into it.
