    Mouse generated antibodies don't bind well to the targeted antigen
  20. How are vaccines made so that ehy do not cause disease?
    • (all of the above)
    • "killing" the infectious agent with heat or other means
    • using a component such as a surface protein of the infectious agent instead of the organism itself
    • genetically engineering the infectious angent to remove the genes that cause disease
    • using a related but non-pathogenic strain of an infectious agent
  21. Which of the following is one key requirement to make a vaccine?
