1. Two of the main, early theories proposed to explain how antigen-
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
specific antibodies develop were the instructional theory and the selective theory. How did the two diff
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
er? Which was ultimately shown to be CORRECT?
0r 0r 0r 0r 0r 0r 0r
CORRECT ANSWER: The selective theory says that, when an antigen receptor binds with an antigen,
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
the cell becomes activated (or the cell is selected to proliferate and secrete more copies of the receptor).
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
The instructional theory says that the antigen receptor molds itself to the antigen. The selective theory
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
was shown to be correct.

2. Often, serendipity plays a role in significant scientific discoveries. In your own words, explain ho
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
w serendipity led Pasteur to discover a cholera vaccine.
0r 0r 0r 0r 0r 0r 0r 0r
CORRECT ANSWER: Pasteur developed the vaccine in chickens, which were in short supply. He chal
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
lenged groups of chickens with cholera bacteria—
0r 0r 0r 0r 0r 0r
some of which were previously exposed to an attenuated version of cholera bacteria. Only the previousl
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
y exposed animals were protected from a new challenge, which led to the use of weakened pathogens a
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
s vaccines.

3. Despite its having been eradicated on a global scale, smallpox is presently considered a potenti
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
al bioterrorism threat. Why? Use evidence to support your answer.
0r 0r 0r 0r 0r 0r 0r 0r 0r
CORRECT ANSWER: After eradication was achieved, smallpox vaccination programs largely ended. A
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
s populations continued to grow over time, an ever-
0r 0r 0r 0r 0r 0r 0r 0r
increasing percentage of the human population remains unvaccinated and thus, is still susceptible to the
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0
disease.

4. Prior to 1999, it was claimed that a thimerosal additive in vaccines was contributing to the rising in
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
cidence of autism. If the claims were true, what resultant trend might you expect to observe in the rate
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0
of autism once thimerosal was removed from vaccines?
r 0r 0r 0r 0r 0r 0r 0r
CORRECT ANSWER: One would reasonably expect a decrease in the rate of autism. However, cases
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
of autism continued to rise after thimerosal was removed from vaccines in 2001.

5. Given the discovery and development of effective antibiotics, make an argument for the continued us
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
e of vaccines against bacterial pathogens. Use evidence to support your answer.
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
CORRECT ANSWER: Antibiotics are used for treatment of disease, not typically for prevention. Antib
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
iotic treatment is not foolproof (considering the rising incidence of antibiotic resistance). Vaccines are a
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0
preventative measure, and prevention is the gold standard for infectious disease control measures.

,6. You have a friend unfamiliar with immunology, and he asks you the following question: "Why do I
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
need the flu shot every year, but don't need an annual chickenpox vaccine?" As a student of immunolog
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
y, how would you explain this discrepancy to your friend? Use evidence to support your answer.
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
CORRECT ANSWER: The virus that causes the flu changes every year -
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
as a result, a new flu vaccine must be prepared each year based on a predication of the most common f
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
orms of the virus likely to be encountered. Vaccines are specific in the type of pathogen against which
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
they protect, and protection against one type does not guarantee protection against pathogens that are cl

osely-related.
7. Provide one benefit and one drawback of generating random recognition receptors during th
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
e development of B cells.
0r 0r 0r 0r
CORRECT ANSWER: A benefit is having the capacity to recognize and respond to diverse pathogens a
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
s they evolve. A drawback is that some recognition receptors could potentially recognize and target hos

t antigens.

a circulation and lymphatics. What is the benefit of such circulation?
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r

illance of the body for the presence of potential pathogens. A significant portion of the human body is c

e immune from future bites of the same species?
0r 0r 0r 0r 0r 0r 0r 0r
CORRECT ANSWER: In the short- 0r 0r 0r 0r
term, probably, as the serum contains protective antibodies against the venom. In the long-
0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r 0r
term, no, as serum treatment is a form of passive immunity. Passive immunity does not generate long
