  • Types of immunity
    • Active immunity
      • Natural
        • Occurs during an infection e.g. Cold virus
        • Antibodies are generated in your own body
      • Artificial
        • Injecting or taking antigens by mouth
        • Takes longer for B and T cells to be activated
        • Gives long lasting immunity
      • Permanent as you produce memory cells
      • Takes time as a primary response to the antigen takes place
    • Passive immunity
      • Natural
        • Antibodies are passed from a mother to child
          • Through placenta or breast milk
      • Artificial
        • Antibodies are transferred meaning memory cells are not created
          • temporary response
        • Provides an instant response
        • e.g. antitoxins are given for tetanus
      • Temporary as no memory cells are created
      • Instant because no immune response takes place
