YOUR BODY GAINS IMMUNITY BY 2 WAYS
Active Immunity
Body produces its own
antibodies against
pathogen antigens. Your
body uses two ways for
the develoing of active
immunity:
Naturally: when a
person is infected with a
pathogen, immune
system fights against
pathogen and produces
antibody
Artificially: when the
person is vascinated
Passive Immunity
Body doesn’t produce its
own antibodies. Ready
antibodies can be taken
from a person who
recovered from the
illness or passed from
mother to baby through
the milk during
breastfeeding.

4. Vaccine

VACCINE
Is a substance made
up of weakened, dead,
or some incomplete
parts of pathogens.
When injected,
vaccine causes an
immune response, so
body acts like it is
injected and produces
antibodies.
