Chapter 16, Problem 7MCQ
Summary Introduction
Introduction:
A disease that is caused due to infection of virus is known as viral infection. A person can acquire the infection by inspiring the respiratory droplets of infected person or by consuming contaminated water or food.

Vaccines are given to provide protection against pathogen causing infections. Which of
the following statements best describes how vaccines work?
a Fever and swelling develop which is the first response in killing a pathogen
b. Antibodies in the vaccine provide the body with nonspecific immunity to an
antigen.
c. An inactivated or killed virus stimulates the body to develop specific immunity to
that type of virus.
d. Heathy bacteria causes the body to release toxins which will protect the body if
later exposed to different type of bacteria.

What can anti-viral drugs target in order to bring a viral infection under control, or to prevent a viral infection in the first place? Ans: To bring an infection under control you would want to inhibit protease so it could not break down the polypeptide protein chain down into new protein coats. C. What can anti-viral drugs target to prevent a viral infection in the first place? Ans: To prevent a viral infection in the first place you could take a medication that would alter the surface receptor, fill in the surface receptor or inhibits the viral surface protein all together.
