Difference between vaccination and immunization
Vaccination vs Immunization:
Prevention is always better than cure. To prevent from a disease, we must have our immune system ready to defence ourselves. We develop our immune system since when we are in the womb. We get vaccinated to prevent from different diseases. But it is still complicated to distinguish vaccination from immunization. Both these terms look similar and they are used interchangeably providing the idea that they are the same. However, when they are deeply observed, the differences between vaccination and immunization can be identified. Therefore, this article will provide a brief explanation on how to distinguish vaccination from immunization along with a description on the two terms.
What is vaccination?
Vaccination is the administration of an antigen to produce immunity to a disease. It is when a virus, or bacteria, is deliberately administered to the body (usually by injection) so that the immune system can prepare to fight a future infection. Vaccinations are a fantastic way of protecting the body against disease. Vaccinations protect the body from specific diseases that can make a person very sick, disable or even kill that person. A vaccination boosts the body’s own defence system, which is also called the immune system. Usually vaccination is considered to be the most effective method of preventing infectious diseases. A vaccine is made from dead or weakened microbes, or parts. Once it is entered to the body, the immune system develops antibodies to it. The antibody stays on patrol in the blood so if this microbe is again met, the body is well prepared to defend the person. The word vaccination was first used by Edward Jenner in 1796. Vaccination is now a common type of disease prevention and something done very quickly by the doctor. There are lots of diseases that one is vaccinated against when he is young like measles, mumps, rubella and polio. There are several types of vaccines which are currently in use such as Killed, Attenuated, Toxoid, Subunit, Conjugate, Experimental and Valence. Vaccines are also called needles, immunizations, vaccination or shots.
What is immunization?
The word immunity refers to the body’s ability to defend itself against a particular disease or infection. Immunization is a safe and effective method of preventing many serious contagious diseases. Immunization works by tricking the body into believing it is experiencing a full-scale invasion by an infectious agent so that the immune system can fortify its defences. Immunization is done through various techniques, most commonly vaccination. Before vaccines, people became immune only by actually getting a disease and surviving it. Immunizations are an easier and less risky way to become immune. Immunization can be achieved in an active or passive manner. Active immunization entails the introduction of a foreign molecule into the body, which causes the body itself to generate immunity against the target. This immunity comes from the T cells and the B cells with their antibodies. Passive immunization is where pre-synthesized elements of the immune system are transferred to a person so that the body does not need to produce these elements itself. Currently, antibodies can be used for passive immunization. For many diseases, immunity is built up over several doses of vaccine. Mothers can pass on immunity to their babies across the placenta during the final months of pregnancy.
What is the difference between immunization and vaccination?
Although the two terms vaccination and immunization are used interchangeably, they have very different meanings. Immunization is the process of rendering a subject immune, or of becoming immune. Immunization can occur naturally as your own body creates immunities to fight off a disease, or through the administration of a vaccine. Vaccination is the use of vaccines to help prevent certain diseases. The vaccine is the actual suspension (in a liquid form given orally or by injection) of weakened or non-live organisms. Therefore, Vaccination means having a vaccine, which also defined as getting the injection. This process prepares our body to fight against a disease. In contrast, immunisation means both receiving a vaccine and becoming immune to a disease, as a result of being vaccinated.
Vaccines contain a dead or alive but weakened germ that can cause a particular disease, like tetanus, against which our body immediately produces antibodies. It is at this point that most believe the body’s defence mechanism kicks in and immunity will occur in the event that the said antigen gains entry again into the body. On the other hand, we get vaccinated even before the body get infected. But when it comes to immunization, vaccines are given to a patient, so that it boosts up the human immune system to provide protection to the body against the disease. Vaccination does not guarantee immunity. Natural immunity happens only after one recovers from the actual disease. Artificial immunity from vaccination is often temporary. Immunization simply means to make someone immune to something. Vaccination, in contrast, means to inject a suspension of attenuated or killed microorganisms, administered for prevention or treatment of infectious disease.
