Rationale 1: Cell-mediated is incorrect because the description is humoral immunity.
Rationale 2:Cytokines is incorrect because the description is humoral immunity.
Rationale 3: Humoral immunity is initiated when an antigen encounters a type of lymphocyte known as a B cell. The antigen activates the B cell, which then divides rapidly to form many copies, or clones, of itself. As they circulate through the body, antibodies physically interact with the antigens to neutralize or target them for destruction by other cells of the immune response.
Rationale 4:Vaccine is incorrect because the description is humoral immunity.
