Question

Toxoids are used in vaccines against
A)Haemophilus influenza type b.
B)diphtheria.
C)herpes simplex type I.
D)polio.
E)diphtheria AND herpes simplex type I.

Accepted Answer

Toxoids are chemically modified toxins (produced by bacteria) that have been rendered nontoxic but still stimulate the immune system to produce antibodies. Diphtheria is a bacterial infection that can cause severe respiratory problems and even death, and vaccination with a diphtheria toxoid is recommended to prevent the disease. The other options (A, C, D, and E) do not involve vaccines that use toxoids.
