Abstract

Miller et al. reported a correlation between BCG immunization policy with the reduced morbidity and mortality for COVID-19. Here, we adopt different data to check this correlation, but we find that the correlation is not significant in general, between countries with BCG and without BCG. It is only marginally significant among countries with BCG when median age is also considered. We argue that more investigation is needed.
