What is immunization?

Immunization is the process by which a person is made immune or resistant to an infectious disease, typically by receiving a vaccine. Vaccines contain weakened or inactive forms of a virus or bacteria, which stimulate the body's immune system to produce antibodies that can recognize and fight off the actual disease-causing organism if the person is exposed to it in the future. Immunization is a safe and effective way to prevent the spread of infectious diseases and protect individuals and communities from outbreaks.

Immunization, also known as vaccination, is the process of introducing a killed or weakened pathogen (sometimes a non-pathogenic microbial antigen) into an organism to produce immunity. This is done with the aim of stimulating a protective immune response without causing the disease that the pathogen causes. The immune response thus produced is directed against that particular pathogen, providing resistance to subsequent infections or disease caused by it.
