They adjusted for variables such as income, access to education and health services, population and age distribution. Through all of the variables, there was a persistent link between higher rates of BCG vaccination and lower peak COVID-19 death rates.

BCG vaccines have been shown to provide broad protection for several viral respiratory illnesses in addition to tuberculosis, he noted.
