Students have asked these similar questions
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.
Decreased immunity is a symptom of HIV/AIDS. This is caused by which of the following?
Select one:
a. HIV destroys antigens. This decreases the possibility of recognizing pathogens in the future.
b. HIV destroys memory T cells. If the body is infected again, there is no antibodies to fight an infection.
c. HIV attacks the macrophages. Pathogens cannot be destroyed once they enter the body.
d. HIV attacks the helper T cells. This allows pathogen cells to enter the body unnoticed.
Suppose a person recovers normally from viral infections, but then gets the same viral infections over and over again- unlike the rest of us.
A. What is probably wrong –B cells, helper T cells and/or cytotoxic T cells?
B. Should this person be at a higher risk of cancer than the rest of us?
C. Should this person be able to lyse bacterial cells as well as the rest of us?
D. Should this person tolerate a graft (from an unreated person) better than you are me?
