Birth weight in Rural Guinea-Bissau. Does maternal BCG scarification affect birth weight?
The Bacillus Calmette-Guérin (BCG) vaccine is associated with reduced mortality that cannot be attributed solely to the protection against tuberculosis. In a randomised trial from Denmark, among children with BCG-vaccinated mothers, BCG vaccination was associated with fewer infectious-disease hospitalisations. his suggest that maternal BCG vaccination affects the health of both mother and child. We examined if maternal BCG-scar status was associated with adverse pregnancy outcomes and the child’s birth weight.
