passive immunity

    Cards (6)

    • passive immunity - produced by the introduction of antibodies into individuals from an outside source
      • no direct contact with the pathogen or antigen is required
    • natural passive immunity - antibodies transferred from mother to infant from breastfeeding
    • artificial passive immunity - you are injected with antibodies
      e.g. plasma transfusion, tetanus shot
    • problems with passive immunity:
      • maternal antibodies pass from placenta into foetal blood
      • breast feeding passes antibodies present in the colostrum
      • protection is temporary and only lasts a few months after birth
    • immunity is produced quickly
    • causes short term protection
