Answer

Answer:

C. a weakened or dead form of a pathogen

Brief Explanations:

Vaccines typically contain a weakened or dead form of a pathogen (like a virus or bacterium) to stimulate an immune - response without causing full - blown disease. Red and white blood cells are not components of vaccines, and synthetic dietary supplements are not what make up vaccines.
