Difference between immunization and vaccination

By Vaccine Injury Lawyer

Did you know there is actually a difference between immunization and vaccination? Most people don’t realize that when you receive a shot or a vaccine, it does not mean you are immunized. Many people are confused with this concept.

The word “immunization” instead of “vaccination” is now pervasive in both medical and mainstream literature, creating a belief that they are one in the same. But, there is a big difference between the two.

Vaccines contain a dead or live but weakened germ that can cause a particular disease, like tetanus. When we are given a vaccine shot, our body immediately produces antibodies against the antigen or foreign body. It is at this point that most believe the body’s defense mechanism kicks in and immunity will occur in the event that the said antigen gains entry again into the body. But, this is not the case with all vaccines.

Immunization means to make someone immune to something. Vaccination, by contrast, according to Dorland’s Medical Dictionary, just means to inject “a suspension of attenuated or killed microorganisms…administered for prevention…or treatment of infectious disease.”

Vaccination does not guarantee immunity. Natural immunity happens only after one recovers from the actual disease. During the disease, the microorganism usually has to pass through many of the body’s natural immune defense systems—in the nose, throat, lungs, digestive tract and lymph tissue—before it reaches the bloodstream.

    In case u are ask in an examination what is the difference between immunization and vaccination

  2. It helped me a lot thank you very much!,

  3. I still don’t understand the difference…. Where is a list of vaccinations? vs a list of immunizations?

    • Immunizations are a hoax… you cannot become immune until after you have had the disease. The fact that these words are used interchangeably in society is deceiving to the public. So the difference is; vaccinations are vaccines and immunizations don’t exist
