If Rh- mother has Rh+ baby, the mother can become sensitized during first pregnancy and then if subsequent fetuses are also Rh+, there can be eryhtroblastosis foetalis.

I read that if mother is O- and baby is any +ve blood group other than O+ , then mother will not become sensitized during first pregnancy because a and b antibodies present in her blood will attack the antigen present on the fetus RBC and there will be no time for the mother to synthesize antibodies against Rh.

My Question : Can't the same logic be applied to all other blood groups? For example : A- mother and B+ baby.
