Countries that have not introduced the BCG vaccine against tuberculosis have been hit hardest by the coronavirus.
Scientists claim that BCG vaccination can reduce the body's susceptibility to infectious diseases. The positive effect is observed now, during the spread coronavirus.
American scientists believe that in countries where the BCG vaccine was not given to the population in a necessary order, COVID-19 infects 4 times more people, and mortality becomes at least several higher percent.
According to them, in Italy and in the United States, BCG vaccination is not given to everyone, so the statistics are significantly aggravated.
Researchers made similar conclusions during an attempt to study the impact of social criteria and economic development on the situation with the coronavirus.

Then they started looking for other reasons and studied BCG.In Ukraine, BCG vaccination is mandatory.
