Passive immunity Notes:
A different type of immunity results when the IgG antibodies in the blood of a pregnant female cross the placenta to her fetus. This protection is called passive immunity because the antibodies in the recipient are produced by someone else. IgA antibodies present in breast milk provide additional passive immunity to the infant's digestive tract while the infant's immune system develops. Because passive immunity does not involve the recipient's B and T cells, it persists only as long as the transferred antibodies last.
