According to Popovich, the idea that people who have undergone these diseases are less likely to become infected with coronavirus do not have any underlying soil.
The doctor also indicated that the effect of the BCG TB vaccine on COVID-19 was also not proven.
“Today this is nothing more than an interesting hypothesis, it has not yet been fully confirmed, there are only scattered data, both laboratory and epidemic. That is, it takes time to confirm,” the immunologist explained.
Other American epidemiologists conducted a similar study and also found a relationship between mortality from COVID-19 in different countries and how long and how widely they used the BCG vaccine, designed to fight tuberculosis. It was possible to establish that the use of this vaccine reduced the level of infection, so that, according to researchers, it can become one of the main tools in the fight against coronavirus.
