Question

Quizplus · Accepted Answer

The placental transmission of antibodies is a form of naturally acquired passive immunity, as the fetus is acquiring pre-formed antibodies from the mother without having to produce them itself. This immunity is temporary and lasts only as long as the transferred antibodies remain in the infant’s bloodstream, but it provides immediate protection for the first few months of life, until the infant’s own immune system can begin producing antibodies.
