Well, well well.OP, I respect your knowledge and I really do think that there is a connection, a correlation between TB and your chances of survival if you would get infected with COVID-19.
But instead of blaming immigrants for everything you should rather research the anti-TB vaccination policy of countries like Italy, Spain, Iran (countries with high COVID-19 mortality rates) and compare them with the anti-TB vaccination policy of countries like Germany, Norway etc (countries with low COVID-19 mortality rates).
Correlation between universal BCG vaccination policy and reduced morbidity and mortality for COVID-19: an epidemiological study
Abstract
COVID-19 has spread to most countries in the world. Puzzlingly, the impact of the disease is different in different countries. These differences are attributed to differences in cultural norms, mitigation efforts, and health infrastructure. Here we propose that national differences in COVID-19 impact could be partially explained by the different national policies respect to Bacillus Calmette-Guerin (BCG) childhood vaccination. BCG vaccination has been reported to offer broad protection to respiratory infections. We compared large number of countries BCG vaccination policies with the morbidity and mortality for COVID-19. We found that countries without universal policies of BCG vaccination (Italy, Nederland, USA) have been more severely affected compared to countries with universal and long-standing BCG policies. Countries that have a late start of universal BCG policy (Iran, 1984) had high mortality, consistent with the idea that BCG protects the vaccinated elderly population. We also found that BCG vaccination also reduced the number of reported COVID-19 cases in a country. The combination of reduced morbidity and mortality makes BCG vaccination a potential new tool in the fight against COVID-19.
