1. What is the role of the bone marrow in the immune system?
  2. What is an autoimmune disease and why does it occur? Why don't autoimmune diseases occur more commonly?
  3. What are the features of the innate immune system and how does it perform its function?
  4. What are the features of the adaptive immune system and how does it perform its function?
  5. What are the two types of adaptive immune responses?
  6. Tetanus is a disease that affects neuromuscular function. The bacteria that cause tetanus produce a toxin that enters the spinal cord and blocks the release of the inhibitory neurotransmitter GABA. People who are risk of developing tetanus can be treated with tetanus toxoid and tetanus antitoxin. Tetanus toxoid is a vaccine  and tetanus antitoxin contains antibodies against the toxin produced by the bacteria. Why would tetanus toxoid and antitoxin be used together to treat people at risk of developing tetanus? How would their effects differ? Why are boosters of tetanus toxoid required?
  7. One suggested treatment for patients with COVID-19 is the administration of blood plasma from people who have recovered from the disease. Why would this treatment be effective? Would this treatment have the same effect as COVID-19 vaccination?
  8. People with HIV infection usually go on to develop acquired immune deficiency syndrome (AIDS). HIV is a virus that destroys helper T cells. How does this affect immune function?
  9. People with AIDS develop rare tumours such as Karposi's sarcoma. What does this tell us about the role of the immune system in tumours?
  10. How could you use a blood test to determine whether someone had been infected with a disease or had developed immunity through vaccination
  11. A person who has failed to respond to hepatitis B vaccine is exposed to potential infection. What be the appropriate response?
