*Breeding females can be vaccinated so that immunity is passively transfered to their offspring via the [[Materno-Fetal Immunity - Introduction#Passive transfer via colostrum|colostrum]] - this protects neonates for the first 8-12 weeks of life.

*Vaccination of young animals should be when the natural passive immunity decreases below the threshold for providing protection. Active immunity should then be stimulated so that the animal has sustained protection. If vaccination is given too early, the natural immunity can interfere with immunisation by binding and neutralising the vaccine antigens.
