One of the preventive methods of Erythroblastosis foetalis is to administrate anti D antibodies to the mother at the 28th and 34th week of gestation as a prophylactic measure. This anti D antibody should be given to Rh– mother immediately after childbirth if she delivers Rh+ child. This will destroy Rh– foetal RBCs by developing passive immunity and preventing the formation of anti D antibodies in the mother’s blood; before the sensitization of the mother’s immune system.
