Indicate whether the following questions are true (T) or false (F).
a. Secondary immune responses take the same amount of time as primary immune responses to become effective.
b. On secondary exposure to an infectious agent there is reduced mortality.
c. Only immune responses made in mucosal secondary lymphoid tissues can provide protective immunity.
d. If an individual acquires a second cold in the same season it will most probably be caused by a different type of cold virus.
e. Plasma cells generated in a secondary immune response have longer life-spans than those made during a primary immune response.
f. During a primary immune response, only memory B cells are generated.
Antibodies against a specific antigen can be injected into a person to provide passive immunity. For which reason is this NOT as effective as the process of vaccination with that antigen?
Select one:
a.
Injection of antibodies may cause allergic reactions, while vaccination never causes allergic reactions.
b.
Injection of antibodies does not provide long-lasting immunity, and vaccination with antigens triggers a clonal selection of B cells and cytotoxic T cells.
c.
Vaccination with antigens triggers a clonal selection of B cells and cytotoxic T cells.
d.
Injection of antibodies does not provide long-lasting immunity.
e.
Injection of antibodies does not provide long-lasting immunity and may cause allergic reactions, while vaccination never causes allergic reactions.
