Booster
Immunization
and
Adjuvants
Immunisation
may
be
administered
by
injection,
oral
consumption,
or
nasal
spray
as
currently
used
for
some
respiratory
viral
diseases.
Booster
immuniza
tion
is
commonly
followed
as
a
way
of
raising
the
antibody
level
by
stimulating
the
memory
cells
to
induce
the
secondary
anamnestic
response.
Some
substances
called
adjuvants
increase
the
efficiency
of
a
vaccine
or
toxoid
by
increasing
the
availability
of
the
antigen
in
the
lymphatic
system.
Common
adjuvants
include
aluminium
sulphate
and
aluminium
hydroxide
in
toxoid
preparations
as
well
as mineral
oils
or
peanut
oil
in
viral
vaccines
