Coronavirus, “where Bcg vaccine required fewer cases and deaths”: the study

Studies on the effect of an ‘old’ tuberculosis vaccination against Covid-19 continue to multiply. Scientists from the University of Michigan have found that countries that required Bacillus Calmette-Guérin (Bcg) to be mandatory (until at least 2000) tend to have reduced infections and mortality rates during the first 30 days of the explosion of the pandemic in the country.

By applying a statistical model based on their findings, the researchers also estimated that only 468 people would likely have died from Covid-19 in the United States on March 29 – 19% compared to the 2,467 deaths that occurred – if the US had adopted mandatory of this vaccine years ago. The study, published in ‘Science Advances’, is only the latest of many conducted in recent months on the link between this vaccine and Covid.

The results suggest that universal immunization with the Bcg vaccine could be useful in the fight against Covid-19: an association that deserves a clinical investigation, say the authors. Available evidence shows that this immunization, typically administered at birth or during childhood to prevent tuberculosis, can help strengthen the immune system against various other infectious diseases. However, the authors warn that their results do not describe this vaccine as a “magic bullet” against Covid. And they invite you to conduct further research.
