Artificially
Acquired
Passive
Immunity
This
arises
from
the
intentional
injection
of
antibody
rich
serum
into
the
circulation.
Before
the
development
of
vaccines
and
antibodies,
this
was
an
important
therapeutic
device
for
disease
treatment.
This
method
is
still
used
for
viral
diseases
as
Lassa
fever,
hepatitis,
and
arthropodborne
encephalitis,
and
for
bacterial
diseases
where
toxins
are
involved.
,For
example,
established
cases
of
botulism,
diphtheria,
and
tetanus
are
treated
with
serum
containing
the
respective
antitoxins.
Since
the
diseases
are
very
dangerous
and
fatal,
no
risk
is
taken
for
introduction
of
antigens.
Instead
already
made
antibodies
are
introduced
into
blood.
Various
terms
are
used
for
the
serum
that
renders
artificially
acquired
passive
immunity.
