APSC 4464 Test 2 - Virginia Tech Questions and
Correct Answers
Vaccines are
Health products that trigger protective immune responses
Vaccines function to
Lessen severity and prevent infection
Core vaccines are
Vital to all pets
Non-core vaccines are
depending on pets risk exposure
Inactivated vaccines are
"Killed" - Highly stable preparations of whole cell virus or bacteria incapable of replicating
following administration
Inactivated vaccine should be administered
in 2 does 2-4 weeks apart
(T/F) Inactivated vaccines have a smaller duration of immunity then attenuated vaccines
True
Inactivated vaccines contain adjuvants, these function to
stimulate immune response
,Examples of diseases requiring inactivated vaccines include
Rabies, Lyme, Bordetella, Influenza, and Leukemia
(T/F) Inactivated vaccines are considered more stable and safer then attenuated vaccines
because the immunizing agent is already dead
True
Inactivated vaccines stimulate what portion of the immune system
Humoral Immunity
Where are Inactivated vaccines administered
Parenterally by Sub Q or IM
where can Inactivated vaccines NOT be administered
Intranasally
Full protection from inactivated vaccines can be seen after how long from the last dose
2-3 weeks
The age at which puppies and kittens can be effectivily immunized is proportional to the
quantity of what
MDA
What is the Window of Susceptibility
Period of time where maternal ABs are too low to provide protection but to high to allow a
vaccine to work
,To beat the window of susceptibility one should vaccinate every 2-4 weeks starting at week
(what) through (what)
8-16
Inactivated vaccines have a shorter duration of immunity than attenuated vaccines
meaning that some animals need a annual (What)
Booster
(T/F) Rabies vaccine is highly immunogenic and considered to be an exception to other
inactivated vaccines
True
What is the timeline for rabies vaccines
Single dose after 12 weeks of age, booster a year later, every 3 years after that
(T/F) Attenuated vaccines are considered to contain live virus
True
Attenuated vaccines induce what types of immune function
Humoral and Cell mediated
(T/F) Attenuated Vaccines are highly immunogenic and can be considered protective after
one dose
True
Why are all vaccines licensed for oral or intranasal administration are attenuated
, Because inactivated or killed vaccines will not immunize when administered on a mucosal
surface
how long after reconstruction of attenuated vaccines should they be administered
1 hour
(T/F) Attenuated vaccines come in multiple dose vials
False
How are attenuated vaccines administered
IN or parenterally (SQ or IM)
What is the minimum age for an initial dose of attenuated vaccines
6 weeks
What is the onset of immunity time in attenuated vaccines
3-4 days
What are non responders and what are the vaccines they don't respond to
Animals genetically incapable of developing an immune response - Distemper (1 in 5000) Paro
(1 in 1000)
(T/F) attenuated vaccines last for many years
True
Revaccination period for dogs with attenuated viral vaccines
3 years
