What kind of immunity protects a developing fetus?
Antibodies that protect the baby, but which were produced in the mother, offer what is known as passive immunity. This relatively short-term help gives the baby’s immune system a chance to start working and finish developing in the period immediately after birth.
How is a fetus protected from maternal immunity?
Mechanisms of fetomaternal tolerance Many mechanisms protect the fetus from the maternal immune system. These include the expression of nonclassical MHC molecules by trophoblast cells (8, 9), tryptophan catabolism by the enzyme IDO (10), T cell apoptosis (11), and the complement system (12, 13).
Do fetuses have an immune system?

Why does the mother’s immune system not reject her fetus?
The researchers discovered that embryo implantation sets off a process that ultimately turns off a key pathway required for the immune system to attack foreign bodies. As a result, immune cells are never recruited to the site of implantation and therefore cannot harm the developing fetus.
Why does the body reject the fetus?

This tolerance counters the immune response that would normally result in the rejection of something foreign in the body, as can happen in cases of spontaneous abortion.
