A new study has been published which gives added muscle to the theory that there is a correlation between countries which give all newborns the BCG vaccine, to prevent tuberculosis, and a flattened curve of Covid-19 infections.
They established this correlation via statistical analyses that factored in “several potential biases”, including “differences in the availability of tests, how cases were reported, and the timing of outbreak onset across countries”.
Berg and colleagues instead focused on changes in the growth rates of Covid-19 cases and deaths, while controlling for at least seven other variables, even including per capita GDP and cultural differences. However, the authors cautioned that their results do not portray BCG as a “magic bullet”, and even found substantial variation in Covid-19 growth rates among BCG-mandated countries.According to Prof Greg Hussey, who leads Vaccines for Africa at the University of Cape Town , the vaccine first came about in 1921 and was distributed to “a number of laboratories worldwide”.
