Large quantities of pure antigen produced using recombinant DNA technology can be used to prepare ________ vaccines.
A) attenuated
B) inactived whole
C) toxoid
D) subunit
E) DNA

Question

Quizplus · Accepted Answer

Large quantities of pure antigen are essential to make subunit vaccines. Recombinant DNA technology can be used to produce a specific protein, which can then be used as the antigen in the vaccine. Attenuated vaccines contain live but weakened microorganisms, while inactivated whole vaccines consist of whole microorganisms that have been killed, neither of which require large quantities of pure antigen. Toxoid vaccines contain inactivated toxins and DNA vaccines introduce a DNA sequence encoding an antigen into cells, but neither of these options involve producing large quantities of pure antigen.
