Benefit and Significance of Immunization


Immunization is one of the most significant advances in public health and
is estimated to have saved more lives in Nigeria,Africa and the world by extension, subsequently over the past 50 years
than any other health intervention.Everybody  wants to do what is best for his or her child.

Diseases are very dangerous. They
can kill. In fact, they kill infants, children and adults.  But, there is a saying that goes “Prevention
is precisely better than cure”. It is good to prevent our bodies from getting diseases so
as to have good health. A healthy person will live long and will be able to
carry out all the activities expected of any living thing.

There are so many ways of preventing
our bodies from getting diseases.
Examples are making our body clean,
making our environment clean, drinking boiled water, cooking our food properly,
taking balanced diet, and doing exercises.
When all these methods are adopted,
our bodies would be free from most water-borne diseases (diseases contracted
through drinking and use of contaminated or unclean water such as cholera,
dysentery and typhoid).

Nonetheless, regardless of a clear knowledge about this  deadly diseases that can
still find their way into the body, and once they get into the body, one
important way to fight them is by immunization, which must have been taken
before the diseases come into the body.
     Therefore, in this
chapter, we shall learn about immunization, how the body
fight against infection, and those
diseases that can be infected by immunization. If you may ask, what is Immunization?
Immunization is the process of
introducing vaccines into the body, to protect the body from certain deadly
diseases and infections. This is done by experts like doctors who give
vaccinations or inoculations, through injections. The injection of dead or
weakened disease causing organisms (germs) into the body is to enable  the persons to develop antibodies (‘soldiers’ of the body that fight
The body some times acquires the
ability to stop its being affected by some diseases. This is known as immunity.
This is how this happens. Once disease germs enter the body, the body produces
antibodies. The antibodies react and destroy the germs. If these antibodies
have been made through immunization, the body makes them again to protect
itself against the particular harmful microorganisms.
The white blood cells in the human
blood produce antibodies regularly to
fight against this germs. At this
stage, the body is said to be immune to the disease.
Note: different vaccinations are for
different diseases. Both children and adults can be immunized.
