Up to a thousand Polish health care workers will take part in research on the BCG vaccine. According to some specialists, Poles go through coronavirus more gently than, for example, Italians or Spaniards. It can be the result of the vaccination against tuberculosis injected in the childhood.

It was only the coronavirus pandemic that allowed us to start research on an issue that has been troubling the world of science for years, – said Dr Hanna Czajka of the University of Rzeszów, coordinator of the research.

In the course of the study, Polish scientists want to check the impact of vaccination against tuberculosis on the immune system.

Polish researchers are pointing out that these vaccinations were not injected in Italy and Spain, where the death rate among the patients infected with coronavirus is around 12 percent and in France, Great Britain, Belgium and the Netherlands – approx. 10 percent. In Poland, where the vaccine is still compulsory, it does not exceed 3 percent.
