Questions and Answers

What is the main topic of Lecture 2 in the course?

  • Adaptive vs. Innate Immune System
  • Self vs. Non-self Tolerance
  • Vaccination Procedures
  • Cells and Tissues of the Immune System (correct)

    • Which statement best describes vaccination?

  • A procedure that involves administration of pathogenic forms of disease-causing agents.
  • A procedure that desensitizes an individual to environmental pathogens.
  • A procedure that induces an immune response. (correct)
  • A procedure that provides short-term protection against pathogens.

    • Why does our immunity to the flu only last for one season?

  • Due to rapid changes in virus strains (mutations). (correct)
  • Due to the nature of the adaptive immune system.
  • Due to the inefficiency of the vaccination procedure.
  • Due to lack of access to universal vaccines.

    • True or False: The Adaptive immune system is fast-acting while the Innate immune system is pathogen-specific.
