As part of a large-scale global trial, scientists in Britain have launched a study to test if the widely-used Bacillus Calmette-Guerin (BCG) vaccine could help protect people against Covid-19.

Developed almost a century ago, BCG vaccine was originally designed to fight tuberculosis (TB). It has also been reported to offer broad protection to respiratory infections.

The new global trial will test the theory that the BCG vaccine could help protect against Covid-19 too.

The University of Exeter on Sunday said that it is leading the UK arm of the trial, called the aBCG vaccination to Reduce the impact of COVID-19 in healthcare workers’ (BRACE) trial.

The BRACE trial is coordinated by the Murdoch Children’s Research Institute (MCRI) in Melbourne, Australia.
