Vaccination without the disease

Vaccination without the disease

A vaccine may contain dead or inactive pathogens, antigens taken from a pathogen, or a live attenuated pathogen. Dead, inactive, and antigen-only vaccine material cannot reproduce. Live attenuated pathogens can reproduce to a limited extent, but are weakened and do not normally cause the full disease.
