BCG shots can give relief to breathless Covid patients

A single shot of the Bacillus Calmette-Guérin (BCG) vaccine could resolve breathlessness and prevent severity in moderately ill Covid-19 patients, researchers of a trial by Parel’s Haffkine Research Institute and BJ Medical College, Pune, said. It is probably the first study on the use of the century-old vaccine, typically given to children against tuberculosis, as treatment for Covid-19 unlike trials that have studied BCG’s role in prevention.
