A) contains empty virus capsids produced by genetically engineered microorganisms such as yeasts.
B) contains viruses inactivated with formalin or another chemical that does not significantly change the surface epitopes.
C) is composed of a weakened form of the pathogen that is generally unable to cause disease.
D) contains toxins that are treated to destroy the toxic part of the molecules while retaining the antigenic epitopes.
E) is composed only of key protein antigens or antigenic fragments from the pathogen.

Quizplus · Accepted Answer

The MMRV vaccine is an attenuated vaccine because it is composed of a weakened form of the pathogen that is generally unable to cause disease. This weakened form can still stimulate the immune system to produce an immune response and provide protection against the pathogen.
