The mother is exposed to fetal blood during childbirth or abortion. The Rh+ proteins on the surface of fetal erythocytes can trigger an immune response in the mother. This creates antibodies in the mother and memory lymphocytes that are able to create more antibodies.
In the second pregnancy with a fetus with Rh factor, the antibodies in maternal blood can cross the placenta to the fetus and attack the fetus's erythocytes to cause erythroblastosis fetalis. The maternal blood in the first pregnancy does not contain such antibodies to cause the problem because the mother has never been exposed to the Rh factor until the time of first childbirth with the antigen.
