Vaccinations

Question 1

IgA

Answer 1

found in mucous, saliva, tears and breast milk; protects against pathogens

Question 2

IgD

Answer 2

part of the B cell receptor; activates basophils and mast cells

Question 3

IgE

Answer 3

protects against parasitic worms; responsible for allergic reactions

Question 4

IgG

Answer 4

Secreted by plasma cells in the blood cells; able to cross the placenta into the fetus ; if present: past exposure

Question 5

IgM

Answer 5

may be attached to surface of a B cell or secreted into the blood; responsible for the early stages of immunity; if present: current exposure

Question 6

Antibody Titer

Answer 6

a type of blood test that determines the presence and level of antibodies in the blood; the amount and diversity of antibodies correlates to the strength of the body’s immune response

Question 7

Vaccination

Answer 7

artificially induced active immunity; expose the immune system to the antigen through vaccination; the immune system responds by making antibodies which will generate immunity to the antigen without actual exposure in nature

Question 8

Live attenuated vaccines

Answer 8

composed of a weakened form of the pathogen that replicates in the body similar to the natural infection but without severe symptoms which creates a strong and long lasting immune response which may lead to lifetime of protection against pathogens

Question 9

Inactivated vaccines

Answer 9

use the killed version of the whole pathogen that causes the disease and do not provide immunity that is as strong as live vaccines; which means that you made need boosters shots overtime in order to get ongoing immunity

Question 10

Subunit, recombinant, polysaccharide and conjugate vaccines

Answer 10

consist of specific pieces of the pathogen which yields a very strong immune response that is targeted to key parts of the pathogen; may need booster

Question 11

Toxoid vaccines

Answer 11

consists of an inactivated toxin made by the pathogen that causes the disease which creates immunity to the parts of the pathogen the cause a disease instead of the pathogen itself ; may need booster shot

Question 12

DNA plasmid vaccines

Answer 12

comprised of small circular piece of DNA called a plasmid that carries genes encoding proteins from the pathogen of interest

Question 13

mRNA vaccines

Answer 13

vaccines based on messenger RNA
