In fact, they are not. Immunization refers to any process by which the an individual may develop resistance to a disease (see diagram). Vaccination is one form of immunization. Vaccination refers to the process of exposing individuals to a biological preparation of a weakened or heat-killed disease-causing pathogen in order to induce an adaptive immune response in their bodies, rendering them immune to the disease. There are forms of immunization that do not involve vaccination. If an individual effectively fights off and survives an infection from a pathogen, that person has been"immunized." In the 1700s, milkmaids who caught cowpox developed immunity to small pox without being vaccinated. Vaccinations often take the form of injections but they are also frequently administered orally or through inhalation. ----------------------------------------------------------- sources: www.WHO.int/en and http://wordnet.princeton.edu/ Here is a faccinating article describing vaccine-produced immunity, or vaccination.

Immunization vs Vaccination
I wondered whether the words "immunzation" and "vaccination" are interchangeable. In fact, they are not. Immunization refers to any process by which the an individual may develop resistance to a disease (see diagram). Vaccination is one form of immunization. Vaccination refers to the process of exposing individuals to a biological preparation of a weakened or heat-killed disease-causing pathogen in order to induce an adaptive immune response in their bodies, rendering them immune to the disease. There are forms of immunization that do not involve vaccination. If an individual effectively fights off and survives an infection from a pathogen, that person has been"immunized." In the 1700s, milkmaids who caught cowpox developed immunity to small pox without being vaccinated. Vaccinations often take the form of injections but they are also frequently administered orally or through inhalation. ----------------------------------------------------------- sources: www.WHO.int/en and http://wordnet.princeton.edu/ Here is a faccinating article describing vaccine-produced immunity, or vaccination.
