Question

Toxoid vaccines,such as the vaccines against diphtheria and tetanus,elicit a(n)
A)TC cell response.
B)immune complex.
C)dendritic cell proliferation.
D)antibody response against these bacterial toxins.
E)antibody response against gram-positive bacteria.

Accepted Answer

Toxoid vaccines are made from inactivated bacterial toxins that have been treated with chemicals or heat to eliminate their harmful effects while preserving their antigenicity. When the toxoid vaccine is administered, it triggers an immune response that leads to the production of specific antibodies against the bacterial toxin. This antibody response provides protection against the disease caused by the bacteria that produce the toxin. Therefore, the best choice is D, which states that toxoid vaccines elicit an antibody response against these bacterial toxins.
