Verified step by step guidance
1
Understand the concept of active immunity: Active immunity involves the activation of the immune system to produce its own antibodies and memory cells in response to a pathogen or a vaccine.
Differentiate between active and passive immunity: Active immunity is acquired when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Passive immunity is provided when a person is given antibodies to a disease rather than producing them through their own immune system.
Identify the methods of acquiring active immunity: Active immunity can be obtained naturally through infection with the actual disease or artificially through vaccination.
Explain how vaccination works: Vaccination involves introducing a weakened or dead form of the pathogen into the body, which stimulates the immune system to produce antibodies without causing the disease.
Clarify why the other options do not provide active immunity: Transfer of maternal antibodies and receiving antibodies from another individual are forms of passive immunity, and taking antibiotics does not involve the immune system producing antibodies.
