Question

What is immunization?

Answer 1

immunization is a way to make you immune to a disease, specifically by taking a vaccine.

Immunization (or vaccination) protects people from disease by introducing a vaccine into the body that triggers an immune response, just as though you had been exposed to a disease naturally. The vaccine contains the same antigens or parts of antigens that cause the disease, but the antigens in vaccines are either killed or greatly weakened. Vaccines work because they trick your body into thinking it is being attacked by the actual disease.
