    RECOMBINANT DNA TECHNOLOGY VACCINE
  18. This vaccine is made with the use of a closely related microbe called the Vaccina Virus?
    SMALL POX VACCINE

    - Patients recieve small pox vaccine made from cow pox virus.
  19. This vaccine contains attenuated microbes (live bacteria or active viruses)?

    - The pathogens in the vaccine are mutated to be Non-virulent ?
    TUBERCULOSIS & MMR VACCINES
  20. A type of vaccine that is use to kill bacteria?

    - When this vaccine is injected, the pathogen cannot divide/replicate, but the host's immune system will develope immunity to the pathogen.?

    E.g: influenza vaccines = inactivate virus
    PLAGUE VACCINE
  21. What are GAMMA GLOBULINS?
    ANTIBODIES
  22. A spot on an antigen where an antibody binds to ____?

    ANTIGENIC DETERMINANT
  23. This substance is capable of inducing a specific immune response ?
    IMMUNOgenes
  24. Molecules that are too small to illicit an immune response?
    - This molecule is the size of a single antigenis determinant?
