Vaccination Flashcards
What is a LIVE attenuated vaccine?
One in which the microorganism loses its pathogenicity but retains capacity for transient growth within inoculated host
What type of host response does a live attenuated vaccine produce?
Mainly induces a CELLULAR response
What are some examples of live attenuated vaccines?
Measles, mumps, polio (sabin), rubella, varicella, yellow fever
What is a killed (inactivated) vaccine?
One in which the pathogen is inactivated by heat or chemicals - maintaining epitope structure on surface antigen is important for immune response.
What type of host response does a killed (inactivated) vaccine produce?
Humoral immunity is induced
What are some examples of killed vaccines?
Cholera, influenza, hepA, polio (salk), rabies
What is a con for inactivated vaccines?
Weaker immune response - so booster shots are usually required
