Out of 170 countries for which data on BCG vaccination and COVID-19 was available, we excluded 28 countries (<100 cases as on May 13, 2020). Among the countries with universal BCG vaccination policy (n-142), a weak but positive correlation (spearmen rho-0.1-0.5, p < 0.05) was observed between COVID-19 cases and deaths per million population and BCG vaccination coverage rates (Supplementary Table 1 ). We further explored the relationship by adjusting for covariates (age > 65 y, cardiovascular disease death rate, diabetes, GDP per capita, beds per thousand population, and the number of tests done per million population) and didn't find any consistent and significant relationship between BCG vaccination rates and COVID-19 burden. These results suggest against any meaningful relationship between country's BCG vaccination coverage and COVID-19 burden.	./cache/cord-355926-24z5lhet.txt	./txt/cord-355926-24z5lhet.txt
