BCG vaccination and socioeconomic variables vs Covid-19 global features: clearing up a controversial issue 2020-05-26 .txt text/plain 3095 151 46 Conclusions: Relying on a very large dataset and a wide array of control variables, our study confirms a strong and robust association between Covid-19 diffusion and mortality with BCG vaccination and a set socio-economic factors, opening new perspectives for clinical speculations and public health policies. In particular Tobit regressions, estimating both the impacts of covariates on the probability of a country reporting more than 100 cases as of April 17 th , and their effect on relative diffusion, was our preferred estimation method. Table 2 shows large and strongly significant effects for per capita gross domestic product and Human Freedom Index (positive) and for the summer season and BCG vaccination (negative), even controlling for more vaccinations. To the best of our knowledge, this is the first study assessing the impact of BCG vaccination on the diffusion and mortality of Covid-19 at the global level by controlling for a comprehensive set of social, economic, geographic and demographic variables. ./cache/cord-340532-fpmd9nzf.txt ./txt/cord-340532-fpmd9nzf.txt
