Subsequent infections by a pathogen that occur after the first exposure to that pathogen are called the secondary response. During the secondary immune response to an infection, the response:
a) Develops more rapidly, lasts longer, and produces a higher titer (amount) of antibody is produced.
b) Develops more slowly and produces fewer antibodies.
c) Is weaker compared to the primary response.
d) Only involves the activation of T cells, not B cells.
