The BCG vaccine, invented in 1921 to stop Tuberculosis, is now showing hope to fight coronavirus (Covid-19).
A BBC report says a team of UK scientists has already begun testing whether the BCG vaccine could save lives from the global epidemic corona. About 1,000 people are taking part in a trial at the country’s University of Exeter. A total of 10,000 people from a few more countries are being included in the test.
Although the BCG vaccine is designed to prevent tuberculosis, there is evidence that it also works against some other infectious diseases. This vaccine is usually applied in childhood. Scientists believe that those who have been vaccinated already will be benefited if they are vaccinated again.
Vaccines are made to strengthen the body’s immune system. A vaccine provides long-term protection against a particular infection. But this process also causes major changes in the body’s immune system.
