Flashcards in CP Tetanus Deck (12):
1

Toxin

immunogenic, antigenic (dangerous)

2

toxoid

chemically weakened toxin, immunogenic but not antigenic

3

active immunization

immunization induced by the introduction of a toxoid into the host's circulationn

4

passive immunization

immunization mediated by the introduction of antibodies, not produced by the host, into the host's circulation.

5

passive vs active immunity

duration and immediacy

passive - immediate, short lived

active - slower, long lived

6

homologous vs heterologous antisera

homo antisera - antisera from another human

hetero antisera - antisera from other species

7

specific immunity

immunity against specific/particular antigen

8

nonspecific immunity

immunity against multiple antigens

9

innate immunity

immunity that the host does not need to develop against any particular antigen

10

acquired immunity

immunity developed against a specific antigen

11

serum sickness

allergic reaction caused by proteins in antisera from a non-human animal. this is why nonhuman antisera is not used anymore in humans

does a history of tetanus provide long lasting immunity against tetanus?

it does not, because a tetanus infection does not produce enough actual toxin to illicit an immune response. thereforl, someone who is unvaccinated and infected with tetanus mutltiple times will never be able to produce an immune response to it.
