Verified step by step guidance

Understand the concept of active immunity: Active immunity involves the production of antibodies by the immune system in response to the presence of antigens. This can occur naturally or artificially.

Identify natural active immunity: This occurs when a person is exposed to a pathogen, such as a virus or bacteria, and the immune system responds by producing antibodies. This process helps the body recognize and fight off the pathogen in future encounters.

Identify artificial active immunity: This is achieved through vaccination, where a person is exposed to a harmless form or component of a pathogen, prompting the immune system to produce antibodies without causing disease.

Differentiate active immunity from passive immunity: Passive immunity involves the direct transfer of antibodies from another source, such as through breastfeeding or antibody injections, and does not involve the recipient's immune system actively producing antibodies.

Recognize the correct answer: The two ways a person can acquire active immunity are through vaccination and natural infection, as these methods involve the immune system actively responding to antigens.
