SECTION 1: IMMUNIZATION FUNDAMENTALS & IMMUNITY
Question 1:
Which of the following best describes the difference between active and passive
immunity?
A) Active immunity involves the transfer of pre-formed antibodies, while passive
immunity stimulates the host's own immune response
B) Active immunity results from the host's own immune response to an
antigen, while passive immunity involves the transfer of antibodies from
another source
C) Active immunity is temporary, while passive immunity is long-lasting
D) Active immunity only occurs through natural infection, while passive immunity
only occurs through vaccination
Rationale: Active immunity develops when the immune system produces
antibodies in response to exposure to a disease organism or vaccine, providing
long-lasting protection. Passive immunity involves receiving pre-formed
antibodies from another source (e.g., maternal antibodies or immune globulin) and
provides temporary protection.
,Question 2:
Live attenuated vaccines differ from inactivated vaccines in which of the following
ways?
A) Live attenuated vaccines cannot produce immunity with a single dose
B) Live attenuated vaccines contain weakened (attenuated) forms of the
pathogen that can replicate in the body
C) Live attenuated vaccines are safer for immunocompromised patients
D) Live attenuated vaccines never require refrigeration
Rationale: Live attenuated vaccines contain weakened versions of the live
pathogen that can replicate in the body to stimulate a strong immune response but
do not cause disease in healthy individuals. They are generally contraindicated in
immunocompromised patients.
Question 3:
Which type of vaccine contains inactivated toxins produced by bacteria?
A) Live attenuated vaccine
B) Inactivated whole-cell vaccine
C) Toxoid vaccine
D) Subunit vaccine
Rationale: Toxoid vaccines use inactivated toxins (toxoids) produced by bacteria
to stimulate immunity. Examples include tetanus and diphtheria toxoids. The
immune system responds to the toxoid by producing antibodies that neutralize the
actual toxin.
Question 4:
What is the primary mechanism of action of adjuvants in vaccines?
A) They kill the pathogen in the vaccine
B) They enhance and prolong the immune response to the antigen
C) They act as preservatives in multi-dose vials
D) They neutralize the antigen
,Rationale: Adjuvants are substances added to vaccines to enhance the body's
immune response to the antigen. They help create a stronger and longer-lasting
immune response, allowing for smaller amounts of antigen to be used.
Question 5:
Natural active immunity is acquired through which of the following?
A) Receiving immune globulin injections
B) Experiencing and recovering from a disease
C) Receiving vaccination
D) Receiving maternal antibodies through breast milk
Rationale: Natural active immunity occurs when a person is exposed to a
pathogen, develops the disease, and the immune system produces antibodies in
response. This results in long-term immunity. Vaccination provides artificial active
immunity.
Question 6:
Which of the following is an example of passive immunity?
A) Immunity following chickenpox infection
B) Immunity following MMR vaccination
C) Immunity acquired through maternal antibodies transferred to a fetus
D) Immunity following influenza vaccination
Rationale: Passive immunity involves the transfer of antibodies from one
individual to another. Maternal antibodies crossing the placenta to the fetus
provide passive immunity to the newborn. This immunity is temporary.
Question 7:
What is the Advisory Committee on Immunization Practices (ACIP)?
A) A committee that approves new vaccines for market
B) A group within the CDC that develops recommendations for vaccine use in
the United States
C) A committee that regulates vaccine pricing
D) A group that manufactures vaccines
, Rationale: ACIP is a committee of medical and public health experts that provides
advice and guidance to the CDC on the use of vaccines and related agents in the
civilian population. Their recommendations become the official U.S. immunization
schedules.
Question 8:
Which of the following best describes "herd immunity"?
A) Immunity that only protects livestock
B) Protection of unvaccinated individuals due to high vaccination rates in the
population
C) Immunity that lasts for a lifetime
D) Immunity acquired through vaccination only
Rationale: Herd immunity occurs when a significant portion of a population is
vaccinated against a contagious disease, providing indirect protection to those who
are not immune. This reduces the spread of disease and protects vulnerable
individuals who cannot be vaccinated.
Question 9:
What is the difference between a Vaccine Information Statement (VIS) and an
Emergency Use Authorization (EUA) fact sheet?
A) There is no difference; they are the same document
B) VIS is used for routine vaccines, while EUA fact sheets are used for
vaccines authorized during public health emergencies
C) VIS is only for children, while EUA is only for adults
D) VIS is required by law, while EUA is optional
Rationale: VISs are required by law to be provided to patients for routinely
recommended vaccines. EUA fact sheets are provided for vaccines authorized
under an Emergency Use Authorization during public health emergencies (e.g.,
COVID-19 vaccines).
