Which of the Following Can Be Used in Creating a Vaccine

Question

Which of the following can be used in creating a vaccine?
A) attenuated bacteria
B) inactivated viruses
C) recombinant proteins
D) attenuated bacteria, inactivated viruses, or recombinant proteins

Accepted Answer

All of the choices listed can be used in creating a vaccine. Attenuated bacteria are live bacteria that have been weakened so that they do not cause disease, but can still stimulate an immune response. Inactivated viruses are viruses that have been killed or inactivated, but still have the ability to stimulate an immune response. Recombinant proteins are proteins that have been produced by genetically modified organisms, often used to create subunit vaccines.
