Q- Define immunization class 9th.
Answer- Immunization is the term that is used to define the procedure to provide or inject a vaccine inside the body of an organism to generate immunity to fight against the microbe of a particular disease. The process of immunization helps in generating antibodies inside the body of an organism to defend against microbes of a specific disease.
The organism’s body is used to gain immunity against the microbes of any specific disease through the process of immunization.
In other words, Immunization is also defined as the procedure of vaccination that can easily be used with interchangeability with inoculation or vaccination.
The above answer is about define immunization class 9th. We hope that this answer is suitable for the same question. If you want to know more about immunization and its types. So, if you are interested in learning about immunization class 9th and its types. So, continue reading this article.
Define Immunization class 9th
Immunization is the process by which resistance is induced (produced) against any disease in both plants and animals. This discussion is totally focused on immunization against several infectious diseases in vertebrate animals, specifically in humans.
The immunization process includes the formation of antibodies in the body of an organism that helps in preventing several diseases.
These antibodies do not react to the entire pathogen but only to a specific part of it, which is called an antigen of that microbe.
An individual can acquire immunity to any specific pathogen in two manners. The first one is active and another one is passive.
In Active immunization, the individual’s own immune system is stimulated to produce antibodies and lymphocytes.
On the other hand in passive immunization, a person receives antibodies or lymphocytes that have been produced by another individual’s immune system.
We hope that you understood the difference between Active immunization and passive immunization.
Types of Immunization
There are mainly two types of immunization:
- Active Immunization
- Passive Immunization
Active immunization stimulates the immune system to produce antibodies against a particular agent (the infectious agent).
Active immunity generally arises naturally, as when someone is exposed to a pathogen. If you do not get this point so you can take the help of the example given below:
For example, any individual who recovers from measles is immune to further infection caused by the microbe causing measles, because the virus stimulates the immune system to produce antibodies that specifically identify and neutralize the pathogen causing measles the next time it is encountered in an individual’s body.
Active immunization can also be artificially induced through vaccination.
Vaccines are preparations containing antigens that stimulate an immune response without causing illness in an individual.
The purpose of vaccination is to ensure that a large number of antibodies and lymphocytes capable of reacting against a specific pathogen are available before exposure to it occurs.
Active immunization is often long-lasting and may be reactivated quickly by a recurrence of the infection or by revaccination in an individual. Now we are going to describe Passive immunization.
We are doing this because in the above answer we told you about define immunization class 9th. So, these two types will help you in learning the concept easily.
Passive immunization help in generating immediate immunity, but not it is long-lasting, protection against a pathogen just like active immunization.
Generally, passive immunization does not occur naturally but in some specific cases, it occurs naturally. Such as when a fetus receives antibodies from the mother across the placenta or when a breastfeeding infant ingests antibodies in the mother’s milk.
