Question

Explain the principle of immunization.

Answer 1

Immunization:

1. The process of developing immune resistance against various disease-causing agents via the body's ability to generate a natural response or through artificial vaccines.
2. Upon the administration of a foreign pathogenic agent, the elicits an immune response by producing antibodies against the specific infectious agents.
3. The immediate antibodies secreted during the primary immune response mature into memory cells for future exposure to the infectious agents.

Procedure:

1. The immunization process begins after the person comes into contact with the infectious agent/vaccine.
2. The body produces antibodies against the infectious agent.
3. The body begins to formulate an immune response to build resistance against the foreign particle.
4. Hence, via this method, the body develops immunity against the infectious agent through the vaccine.
5. This process provides protection against various infectious diseases such as rabies, etc, thus helping to reduce the mortality rate.
6. Various vaccines have been synthesized against diseases like tetanus, smallpox, measles, etc.
