Question

Quizplus · Accepted Answer

Inactivated virus vaccines, also known as killed vaccines, involve treating the virus with a chemical such as formaldehyde to destroy its ability to cause disease while preserving the virus's ability to induce an immune response. The injected preparation used for the polio vaccine contains inactivated poliovirus, making it an example of an inactivated virus vaccine. Option B, attenuated virus vaccines, involve creating a weakened form of the virus, while option C involves using isolated viral proteins, neither of which applies to the polio vaccine.
