COVID-19: A model correlating BCG vaccination to protection from mortality implicates trained immunity

O_LIWe use a data quality model to demonstrate that BCG vaccination is correlated with protection from death from COVID19 C_LIO_LIFrom a mechanistic perspective, BCG is well described to elicit its protective non-specific effects through the process of trained immunity. C_LIO_LITherapeutically enhancing trained immunity may therefore be an important mechanism in protection from the lethal effects of COVID19 C_LI
