IMMUNOLOGY

Detailed explanation-1: -Immunogenicity is the ability to induce a humoral and/or cell-mediated immune response. Antigenicity is the ability to specifically combine with the final products of the immune response (i.e., secreted antibodies and/or surface receptors on T cells) (Owen et al. 2013).

Detailed explanation-2: -Humoral immunity protects the body against extracellular pathogens and their toxins. Cell-mediated immunity protects the body against intracellular pathogens. Pathogen recognition. Recognises pathogens circulating in blood or lymph.

Detailed explanation-3: -T cells are responsible for cell-mediated immunity. B cells, which mature in the bone marrow, are responsible for antibody-mediated immunity. The cell-mediated response begins when a pathogen is engulfed by an antigen-presenting cell, in this case a macrophage.
