Question

Erythroblastosis foetalis can be avoided by administering anti Rh antibodies to the mother immediately after the birth of the first child. How does this work to correct the situation? Explain it in detail.

Answer 1

An injection of anti‐Rh antibodies can be given to prevent erythroblastosis foetalis. Rh^- women should receive this injection before delivery, and soon after every delivery, miscarriage, or abortion. These antibodies bind to and inactivate the foetal Rh antigens before the mother’s immune system can respond to the foreign antigens by producing her own anti‐Rh antibodies.
