SYDNEY (Reuters) - Thousands of Australian healthcare workers will begin a trial to see if a century-old vaccine for tuberculosis can fight off the new coronavirus, researchers said, joining a global test of the unorthodox solution underway in several countries.
The vaccine bacillus Calmette-Guérin, or BCG, is given to more than a million children a year in countries with tuberculosis, but researchers say it may also combat the new coronavirus because of its ability to power up the immune system broadly. Vaccines help the body fight off viruses and diseases by building up a person's immunity but do not cure diseases.
