Question

what is the principle of immunization​

Answer 1

Answer:

Immunization is the process whereby a person is made immune or resistant to an infectious disease, typically by the administration of a vaccine. Vaccines stimulate the body’s own immune system to protect the person against subsequent infection or disease.

This happens because when the immune system first sees an infectious microbe, it responds against it and then remembers it specifically. So the next time that particular microbe, or its close relatives enter the body, the immune system responds with even greater vigor. This eliminates the infection even more quickly than the first time around. This is the basis of the principle of immunisation.

Answer 2

Explanation:

The basic theory of immunization is that the body begins to produce antibodies against it upon administration of the vaccine so that the individual is safe from disease.
