What Is Immunisation?

Immunisation is explained as a method of disease prevention in which both children and adults are protected from harmful infections with which they come into contact with, or it may otherwise produce serious illness or even death.

A person can be immunized by giving vaccination (an injection) against a disease and this helps the person to develop the ability to fight off an infection and it also reduces the likelihood of developing the illness and the spreading of the disease to others.

This plays a major role in adults as well as children. The process of immunization usually begins in childhood, but it is important to keep up to date with regular vaccinations throughout adult life to make sure a person is protected from infections.

Immunization is considered as the most effective medical intervention to prevent deaths and reduce diseases by World Health Organization and has also reduced the death rate in patients infected with diseases like diphtheria, Haemophilus Influenzae Type B infection and measles.

How Does Immunization Work?

A natural process where in a human body when exposed to new virus or bacteria for first the time can cause a disease by the infection as it reacts very slowly by taking longer time to clear the bug from the body, and for the second time it is much less likely to cause disease than the first infection as the body recognizes the bug much faster than before and tries to fight by making antibodies against that disease before the disease develops or becomes more severe.
Chicken pox can be cited as a best example for this (if once a person has had one attack of chicken pox, they are much less likely to develop the disease again). This is all based on the functioning of the body’s immune system.

Artificial way of immunization can be done by giving a modified or killed version of the bug in a ‘vaccine(a product made from killed or live, weakened strains of viruses or bacteria)’ which allows the system to recognize and respond to the modified version in the same way as it would to a natural infection .

The act of giving a vaccine to a person is referred as Vaccination. A vaccine triggers an immune response after it is injected into body by protecting the person who comes into contact with strains of that disease again in the natural environment.

What Is The Difference Between Vaccination And Immunization?

Immunization generally happens in the body after the vaccination. The vaccine stimulates your immune system so that recognizes the disease and protects from future infection by making a person immune to the infection.
Immunization may also be explained as the process of both getting the vaccine injected into the bosy and becoming immune to the disease following vaccination.s
