  2. 8. provided when a person is given antibodies to a disease rather than producing them through his or her own immune system
  3. 9. a toxin or other foreign substance which induces an immune response in the body, especially the production of antibodies.
  4. 10. A type of immune cell that is made in the bone marrow and is found in the blood and in lymph tissue.
  5. 11. Immunity that is naturally existing, Natural immunity does not require prior sensitization to an antigen
  6. 16. occurs when a virus has infected a cell, replicated new virus particles,

  8. 12. a method by which a virus can replicate its DNA using a host cell.
  9. 13. A type of white blood cell that makes antibodies.
  10. 14. treatment with a vaccine to produce immunity to a particular infectious disease or pathogen.
  11. 15. a large phagocytic cell found in stationary form in the tissues or as a mobile white blood cell, especially at sites of infection.
