What is Immunization?
The correct answer and explanation is:
Immunity and Its Types
Immunity is the body’s ability to resist harmful microorganisms, toxins, or infections. It is a defense system composed of biological processes that detect and eliminate pathogens, preventing diseases. The immune system consists of white blood cells, antibodies, and various bodily defenses.
Types of Immunity
- Innate Immunity (Natural or Non-Specific Immunity) – This is present from birth and provides a general defense against pathogens. It includes physical barriers (skin, mucous membranes), chemical barriers (enzymes in saliva, stomach acid), and immune cells (phagocytes).
- Adaptive Immunity (Acquired or Specific Immunity) – Developed over time, it involves a targeted response against specific pathogens. It includes:
- Active Immunity: The body produces its own antibodies in response to an infection or vaccine.
- Passive Immunity: Temporary immunity acquired from an external source, such as maternal antibodies or antibody injections.
Acquired vs. Artificial Immunity
- Acquired Immunity develops when a person is exposed to diseases or vaccinated. It creates memory cells that recognize the pathogen in future infections.
- Artificial Immunity is induced through medical intervention, such as vaccines or antibody injections, rather than natural infection.
Vaccination
Vaccination is the process of introducing a weakened or inactive form of a pathogen to stimulate the immune system. It helps the body recognize and fight infections in the future. Examples include vaccines for polio, measles, and COVID-19.
Immunization
Immunization is the process of making a person immune to a disease, often through vaccination. It helps develop long-term immunity, reducing the risk of infections and disease outbreaks.
Now, I’ll generate an image related to immunity and vaccination.
Here is the generated medical illustration of the human immune system, showing how white blood cells fight off pathogens, along with vaccination triggering an immune response. Let me know if you need any modifications!
