Loan immunity
The maternal immunity is an early form of immunity , which cross the placenta antibody type immunoglobulin G from the mother through the placenta (placenta) in the womb of the unborn is transmitted child. It is part of the nest protection and is intended to protect the child from infections after birth until the development of its own immune system, which takes place between the fourth and sixth month of life through the formation of antibodies of the type immunoglobulin M and immunoglobulin G. The protective function of loan immunity is subject to a time limit, because the antibodies are gradually broken down by the infant in the first few months after birth.
