In the course of research, experts found out that the drug created on the basis of the coronavirus vaccine in combination with BCG, i.e. vaccination against tuberculosis, based on the properties of the bacillus Calmette-Guerin, showed a good result.
To strengthen the created formula, alum, salts of a number of metals, were used. The drug was tested in transgenic mice with the introduction of the human receptor ACE2, through which the coronavirus enters the body.
The test group of mice was injected with the drug, and 21 days after that, the virus was injected. None of the individuals not only did not get sick, but their bodies did not even have traces of the pathogen, while the level of antibodies in animals was higher than in people who had had coronavirus.
