An immunization against diphtheria is an example of which type of immunity?
  1. Active natural
  2. Active artificial
  3. Passive natural
  4. Passive artificial
Explanation
Answer: B - An immunization against diphtheria is an example of active artificial immunity. This type of immunity is accomplished when an antigen in the vaccination leads the body to actively produce antibodies against the specific antigen. It is artificial since it is accomplished with a manmade vaccination, rather than actually getting the infection and then producing antibodies.
