Researchers suggest that a routine TB vaccine for children in countries with high rates of bacterial disease could help reduce deaths from Covid-19.

After taking into account the differences in factors that may affect vulnerability to the coronavirus – such as income, education, health services and age distribution – the scientists found that countries with higher rates of Bacille Calmette-Guarin (BCG) tuberculosis vaccinations had Covid mortality rates19.

A good example was Germany, which had different vaccine plans before East Germany and West Germany were unified in 1990, according to the researchers. Mortality rates of Covid-19 among the elderly are almost three times higher in western Germany than in eastern Germany, where more elderly people received the vaccine as infants, they found.
