Questions and Answers

What is the main topic of Lecture 2?

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

    • What is the primary purpose of vaccination?

  • 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
  • A procedure that involves administration of pathogenic forms of disease-causing agents

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

  • Insufficient immune system response
  • Due to rapid changes in virus strains (mutations) (correct)
  • Because the flu virus evolves rapidly
  • Lack of proper vaccination techniques

    • Is the statement 'The Adaptive immune system is fast-acting while the Innate immune system is pathogen-specific' true or false?
