In contrast, middle high and high income countries that never had a universal BCG policy (5 countries) had a larger mortality rate, with 16.39 ± 7.33 deaths per million people. We wondered if countries that established a universal BCG policy earlier would have a reduced mortality rate, as older people that are more severely affected by COVID-19 would be protected. Consistent with a role of BCG in slowing spread of COVID-19, middle high and high income countries that never had a universal BCG policy (5 countries) had about 4 times the number of cases per million inhabitants, with 264.90± 134.88. . https://doi.org/10.1101/2020.03.24.20042937 doi: medRxiv preprint Figure 3 : Higher number of COVID-19 cases were presented in countries that never implemented a universal BCG vaccination policy.	./cache/cord-300729-35meen0h.txt	./txt/cord-300729-35meen0h.txt
