Placental transfer of tetanus toxoid antibodies in Nigerian mothers.

The geometric mean of the ratio of cord blood to maternal antibody levels for Nigerian pairs was lower than that of the UK pairs (0.776 vs. 1.306), suggesting a flaw in the transplacental transfer of antibodies. Possible mechanisms involved in blocking placental transfer of tetanus toxoid antibodies may be high maternal IgG levels and heavy malarial placental infection. This block of placental transfer of antibodies affects current immunization programs and necessitates further study.
