Over a million people around the world die every year from

diseases that can be prevented by immunization.

Immunization can be oral or by injection

In brief:

 It makes the body resistant to targeted disease

 It reduces infant mortality rate

 It makes the body produce antibodies

.
Antibodies

Antibodies are chemicals produced by the body (white blood

Note: Substances that stimulates the production of anti-

bodies are called Antigens. (Vaccines are antigens because

they stimulate the body to produce antibodies for specific dis-

eases)
