Can TB Vaccine Help Fight Coronavirus ?

A new research that emerged this week is supporting the use of tuberculosis vaccine Bacillus Calmette-Guerin (BCG) as a tool in the fight against coronavirus.

Researchers found that countries where many people have been given the vaccine have had less mortality from Covid-19.

Which again points to research that suggests BCG can boost people’s immunity in general, and perhaps help against the coronavirus.

“What distinguishes our work is that we were very careful in removing variables,” said Carolina Barillas-Mury, a distinguished investigator with the National Institutes of Health who worked on the study.”When we removed them, if this was not true, the association should have disappeared. Instead of disappearing, it became stronger and stronger — more straightforward,” she told CNN.

However, the researchers caution that clinical trials are needed to prove the vaccine’s impact on severe Covid-19. 1

“The nice thing is that it’s given only once. It’s potentially quite feasible to scale up production of the vaccine, if it works and it’s safe,” said Dr. Wafaa El-Sadr, a Columbia University professor of epidemiology and director of ICAP, a global health program.
