Rubeola Can Be Effectively Prevented with the MMR Vaccine

Multiple Choice

Rubeola can be effectively prevented with the MMR vaccine. The child in this case has not received any vaccines, because he has been receiving chemotherapy. Why wasn't he given the MMR vaccine?

A) It is an attenuated vaccine and there is a small risk that the virus used in it may revert to virulence, causing serious illness in the immunocompromised patient.
B) It is an inactivated vaccine and there is a small risk that the virus used in it may revert to virulence, causing serious illness in the immunocompromised patient.
C) The MMR vaccine is known to cause complications such as autism, and this child already has enough problems with leukemia.
D) It is a toxoid vaccine-these vaccines contain deactivated microbial toxins; since the child is severely immunocompromised, the toxin used in the vaccine will damage all of his cells.
E) The patient is a child, so will not be able to tolerate any egg proteins that may be present in the MMR vaccine, which is produced in eggs.
