Maternal infection with Trypanosoma cruzi and congenital Chagas disease induce a trend to a type 1 polarization of infant immune responses to vaccines.
BACKGROUND: We previously showed that newborns congenitally infected with Trypanosoma cruzi (M+B+) display a strong type 1 parasite-specific T cell immune response, whereas uninfected newborns from T. cruzi-infected mothers (M+B-) are prone to produce higher levels of proinflammatory cytokines than...

METHODOLOGY: Infants (6-7 months old) living in Bolivia, an area highly endemic for T. cruzi infection, and having received Bacillus Calmette Guerin (BCG), hepatitis B virus (HBV), diphtheria and tetanus vaccines, were enrolled into the M+B+, M+B-, M-B- groups mentioned above.
