from MDlink.. site Preliminary studies early in the pandemic found evidence that countries with Bacillus Calmette-Guérin (BCG) vaccination programs, which fights tuberculosis, could be associated with a reduced number and/or severity of COVID-19 cases. While clinical trials are ongoing to further investigate, a University of Houston computational biology researcher is reporting cross reaction between the two illnesses that might help explain what could be driving immunity brought on by the BCG vaccination.
"The protection against SARS-CoV-2 induced by BCG vaccination may be mediated by cross-reactive T cell lymphocytes, which recognize peptides displayed by class I Human Leukocyte Antigens (HLA-I) on the surface of infected cells," reports Dinler Amaral Antunes, assistant professor of computational biology and a corresponding author of the work published in the journal Frontiers in Immunology...
