Answer 15

bound to mast cells and basophils involved with parasites and atop

Question 16

An attenuated vaccine is one that:

Answer 16

uses an organism that has been injured or adapted so it no longer causes disease

Question 17

Answer 17

placental transfer, colosturm, hyperimmune serum, monoclonal antibodies,

Question 18

core vaccine

Answer 18

recommended to all animals in a susceptible population

Question 19

for a vaccine to be effective and cause an immune response the bodys immune system must view it as

Answer 19

foreign and dangerous

Question 20

Answer 20

FALSE

Question 21

which of the following is not a current method used for vaccine delivery in animals

Answer 21

IV

Question 22

It is important for most vaccine schedules that the final booster vaccine is given beyond the age of 16 weeks. This is because:

Answer 22

Vaccine efficacy increases now that maternal, passive immunity has likely diminished

Feline herpes virus, panleukopenia, calicivirus

Question 26

Creating a vaccine requires that certain criteria are met. From the following list, which item is not considered a criterion for a successful vaccine?

Answer 26

No side effects occur from vaccine administration.

Question 27

One of the downfalls of natural immunity is:

Answer 27

The immunization can overwhelm and kill the animal before it can respond.

Question 28

Of the several different means for creating immune-stimulating vaccines, list three things (from the course) that are used to manufacture the vaccines. (

Answer 28

subunit vaccines - isolating genetic codes for an antigen
Live vaccines- administering the DNA of a disease causing organism into a non disease causing organism of that species killed vaccines- exposure to heat or chemicals to create a killed vaccine
attenuation - injuring or weakening the organism so it cannot cause cause disease
