Verified step by step guidance

Understand the different types of immunity: Innate immunity is the body's first line of defense and is non-specific. It does not involve antibodies. Passive immunity involves receiving antibodies from another source, such as mother to child through breast milk, and does not involve the body's own immune response.

Recognize that active immunity involves the body's own immune system responding to a pathogen or a vaccine by producing antibodies. This is a specific response and involves memory cells that help the body respond faster upon future exposure to the same pathogen.

Identify that vaccines are designed to stimulate the body's immune system to develop active immunity. They contain antigens that mimic a pathogen, prompting the immune system to produce antibodies and memory cells without causing the disease.

Differentiate between cell-mediated immunity and antibody-mediated immunity: Cell-mediated immunity involves T-cells and does not primarily involve antibodies, whereas antibody-mediated immunity (a part of active immunity) involves B-cells producing antibodies.

Conclude that the type of immunity that occurs when antibodies develop in response to a vaccine is active immunity, as it involves the body's own immune response to produce antibodies and memory cells.
