The Adaptive Immune System: Artificially Acquired Immunity

Learning Objectives for "The Adaptive Immune System: Artificially Acquired Active and Passive Immunity"

After completing this section you should be able to perform the following objectives.

1. Define and give at least one example of each of the following types of immunity:

a. artificially acquired active immunity
b. artificially acquired passive immunity

2.* List 3 different forms of antigen that may be used for artificially acquired active immunity and state 2 common examples of each.

3. State what DTaP stands for and what specifically is being injected with the DTaP vaccine.

4. Briefly compare active immunization with passive immunization in terms of tetanus prophylaxis.

5. Define adjuvant.

6. In artificially acquired immunity, active immunization is preferred over passive immunization. Explain why.

7.* A patient with a deep puncture wound who has never received a DTP vaccination is given both Td and TIG. Another patient with an identical wound and who had 4 DTP vaccinations as a child and a Td booster 3 years ago is given nothing. Discuss the reasoning behind this. (see Fig. 2)
