Immunity depends upon the production of disease-specific antibodies to destroy harmful bacteria.

Humoral immunity depends upon the production of disease-specific antibodies to destroy harmful bacteria.

Explanation:

There are two types of immunity, humoral immunity, and cell-mediated immunity. The first one is quicker and secrets specifics antibodies that the body has stored from the previous contact with the harmful bacteria to destroy it. The second type is slower and is not specific, it secretes cytokines to destroy pathogens in general.
