Difference Between Vaccination And Immunization

Vaccination and immunization seem synonymous, while there is a difference between vaccination and immunization. Vaccination is the act of giving the vaccine, however, this does not guarantee that the person is immunized. Throughout administering a vaccine it is possible to achieve immunization. Let us know the detailed key difference between vaccination and immunization.

Difference Between Vaccination And Immunization In Tabular Form



A process that involves Introducing weakened/deactivated disease-causing microbes into a person. A process that starts after the person is exposed to the vaccine and the body starts building resistance to that disease
A vaccine is usually injected. It is not administered while the body develops resistance from vaccines.
It does not guarantee complete resistance to disease. When a person recovers fully, he gains complete immunity from the disease.
When mutation happens to the microbe, it might render the vaccine ineffective. Variations of a disease impact the body’s ability to generate an immune response as same to vaccination.

Vaccination Vs. Immunization – Overview

“Vaccines or Immunizations are essential. Because they protect against diseases such as measles, mumps or rubella”, “Immunizations are an easier and less risky way to become immune” or “It is important to emphasize that immunizations, which until recently were “only for children”, are beginning to become an excellent form of protection for all ages ”.

What is Vaccination?

In medical institutes, the vaccine is the ‘suspension of live attenuated or inactivated microorganisms or their fractions, that are administered to the susceptible healthy individual in order to induce active protective immunity against the disease corresponding infectious disease ‘, On the other hand,  immunization is the’ action or effect of immunizing or immunizing ‘.

What Vaccines Do?

Normally, immunization can be achieved, and not always, by administering a vaccine. That is, the goal is immunization and the means, or one of them, is vaccination. It is not accurate to say that “the world will have about 80 % immunizations”, since, this number of vaccines is administered, their effectiveness is not 100%, so the number of immunizations that will be achieved will be less.


Vaccines are essential while they protect against:

  • It protects against various diseases like “measles, mumps or rubella.”
  • Vaccines are an easier and less risky way to become immune

What is Immunization?

It is a process that resists diseases that are acquired or induced in plants and animals. Immunization can produce naturally as if a person is exposed unintentionally to a pathogen (an infectious agent), or it may be brought about artificially through a vaccine.

Immunization provides resistance to a particular pathogen by means of antibody proteins that are targeted to eliminate that pathogen from the body. They do not fight against the entire pathogen but only to a specific part of it, which is called an antigen. An individual can acquire immunity for a specific pathogen is a complex system, so immunity is divided into two types:

  • Active Immunity
  • Passive Immunity

Active Immunity

Active immunity originates from exposure to a pathogen. Surface markers on the pathogen surface act as antigens, that are binding sites for antibodies. An example of natural activity immunity is fighting off a cold while building up resistance to a disease due to immunization is an example of artificial active immunity.

Passive Immunity

It does not require the body to make antibodies to antigens. Several antibodies are introduced from outside the organism. The body protection against certain infections by getting antibodies through breast milk is an example of natural passive immunity. The getting of injection that is a suspension of antibody particles is an example of artificial passive immunity.
