What is immunization?

Immunization refers to the process of making an individual immune to infection, usually by introducing a vaccine into the body. Vaccines work by stimulating the immune system to recognize and combat pathogens, such as viruses or bacteria, thereby providing protection against future infections. This protective response is crucial in preventing the spread of contagious diseases and maintaining public health.

Although receiving a vaccination is a part of the immunization process, it is not the entirety of what immunization encompasses. It involves a more holistic approach, including the preparation of the immune system to recognize and fight off diseases, which can include multiple doses and types of vaccines. The focus on making a person immune illustrates the goal of preventing disease rather than simply administering a shot or a medication.
