Step 1: Begin by understanding the concept of immunity. Immunity refers to the body's ability to defend itself against pathogens, such as bacteria, viruses, and other harmful agents.
Step 2: Learn about the different types of immunity. There are two main categories: innate immunity (non-specific, immediate response) and adaptive immunity (specific, learned response). Adaptive immunity can be further divided into active and passive immunity.
Step 3: Define active immunity. Active immunity occurs when the immune system is stimulated to produce its own antibodies and memory cells in response to exposure to a pathogen or a vaccine. This type of immunity is long-lasting.
Step 4: Define passive immunity. Passive immunity involves the transfer of antibodies from another source, such as through breast milk or antibody injections. This type of immunity is temporary and does not involve the production of memory cells.
Step 5: Relate vaccination to active immunity. Vaccination introduces a harmless form of a pathogen (or its antigens) into the body, prompting the immune system to produce antibodies and memory cells. This process is an example of active immunity because the body actively generates its own immune response.
