In the United States testing a vaccine against tuberculosis and polio to combat the coronavirus SARS-CoV-2, which was actively used in a number of countries such as the USSR. About it reports The Washington Post.
According to Professor Texas A&M University Jeffrey Cirillo, TB BCG is “the world’s only vaccine that can be given to combat COVID-19 right now.” It is noted that such a vaccine is not directly directed against SARS-CoV-2, but may reduce mortality from COVID-19. Currently in Texas, the study received BCG 450 of 1,800 people.
The American edition draws attention to the fact that in Pakistan, the population of which is actively vaccinated against tuberculosis, the mortality rate from coronavirus infection is significantly lower than in the United States, where such vaccinations are done much less frequently.
According to the Deputy Director for science Management on sanitary inspection behind quality of foodstuff and medicines of the United States, a virologist Konstantin Chumakov, in 1960-e and 1970-e years his parents, who worked on vaccines in the Soviet Union, every fall had given him oral polio vaccine, says scientist, contributed to the high protection against influenza.
Currently, according to The Washington Post, Chumakov, together with one of the discoverers of HIV, Robert Gallo works at the University of Maryland testing of polio vaccine against coronavirus infection.
Meanwhile, the publication notes that in Brazil and Israel, where the population actively have used BCG, the mortality rate from COVID-19 not lower. The Washington Post does not exclude the possibility that BCG may provoke an excessive immune response to SARS-CoV-2 and, as a consequence, worsening of COVID-19. The publication concludes that the effectiveness of vaccines against tuberculosis and polio in respect COVID-19 still needs careful study.
In April, the world health organization stated that no evidence of protection for TB vaccine BCG against infection with a coronavirus.
In March, epidemiologists from the US has found a link between the vaccine against tuberculosis BCG and a reduction in the incidence of coronavirus.
