Evidence from a natural experiment in Sweden	2020-08-23		.txt	text/plain	2819	151	56	Instead, this paper takes advantage of a rare nationwide natural experiment that took place in Sweden in 1975, where discontinuation of newborns BCG vaccination led to a dramatic fall of the BCG coverage rate, thus allowing us to estimate the BCG's effect without the biases associated with cross-country comparisons. found that countries with universal Bacillus Calmette-Guérin (BCG) childhood vaccination policies tend to be less affected by the COVID-19 pandemic, in terms of their number of cases and deaths [7] . In this study, we took advantage of a change in vaccination policy in Sweden to investigate the link between BCG vaccination in infancy and Covid-19 cases, hospitalizations and deaths, using a regression discontinuity approach. For instance, this study estimates the effect of universal BCG vaccination for individuals born around April 1st 1975, who are in their mid-forties during the COVID-19 pandemic, and cannot be generalized to the entire population.	./cache/cord-292372-kn27ghlv.txt	./txt/cord-292372-kn27ghlv.txt
