Description

a modified version of a germ or other substance related to a disease, usually given by injection (a shot). It is used to stimulate the immune system to resist that disease for a period of time, or even permanently. For instance, the HPV vaccines help to prevent cancer by helping the body fight human papilloma virus (HPV), which can cause many types of cancer. Research continues into vaccines to help a person who has cancer, with recent progress in prostate cancer treatment.
