what are the 2 artificial methods of immunity
active immunity and passive immunity
active immunity
administer antigens that cause adaptive immunity with memory B cells
passive immunity
administer antibodies formed by immune individual or animal
passive imunotherapy administers what
antiserum that contains preformed antibodies
what does passive immunotherapy provide protection against
infection
what are limitations of antisera
allergic reactions, can degrade quickly , not protected from future infections
what are the 4 vaccine types
attenuated
inactivated
toxoid
combination
attenuated is the process of what
of reducing virulence of pathogen
how is attenuated vaccines made
with modified live thing
active microbes from attenuated vaccines causes what immune response
strong immune response
inactivated vaccines do what to make it
killed the thing
are inactivated safer or more dangerous than attenuated vaccines
safer
taxoid vaccines are made how
with chemically modified toxins
how do taxoid vaccines work
they stimulate antibodies against the toxin
combination vaccines administer what
its the simultaneous administration of antigens from several pathogens
