PTCB Immunization Test Questions and
Complete Solutions Graded A+
Active Immunity - Answer: acquired by either contracting the disease, or being vaccinated
adjuvent - Answer: a vaccine component separate from the antigen that helps trigger an immune
response
Attenuated vaccine - Answer: vaccine composed of a weakened form of the pathogen that is generally
unable to cause disease
Hepatitis A (acute) - Answer: An acute viral disease of the liver transmitted through contaminated food
or water
Hepatitis B - Answer: inflammation of the liver caused by the hepatitis B virus (HBV), which is
transmitted sexually or by exposure to contaminated blood or body fluids
Live Vaccine - Answer: A vaccine in which live virus is weakened (attenuated) through chemical or
physical processes in order to produce an immune response without causing the severe effects of the
disease. Live vaccines currently licensed in the United States include measles, mumps, rubella, varicella,
rotavirus, yellow fever, smallpox, and some formulations of influenza, shingles, and typhoid vaccines.
Also known as an attenuated vaccine.
Passive Immunity - Answer: Protection against disease through antibodies produced by another human
being or animal. Passive immunity is effective, but protection is generally limited and diminishes over
time (usually a few weeks or months). For example, maternal antibodies are passed to the infant prior to
birth and protect the baby for the first 4-6 months of life
Pertussis - Answer: Bacterial infectious disease marked by a convulsive spasmodic cough, sometimes
followed by a crowing intake of breath. Also known as whooping cough.
VAERS - Answer: Vaccine Adverse Event Reporting System
