Cancer vaccine
Cancer vaccine
A Cancer vaccine (/ˈkænsər vækˈsiːn/) is a type of vaccine that either treats existing cancer or prevents development of a cancer.
Etymology
The term "cancer vaccine" is derived from the Latin cancer meaning "crab" or "creeping ulcer" and vaccina meaning "of the cow", referring to the use of cowpox material in vaccination.
Types of Cancer Vaccines
Cancer vaccines can be broadly classified into two types: Preventive (prophylactic) vaccines and Treatment (therapeutic) vaccines.
Preventive (prophylactic) vaccines
Preventive vaccines are used to prevent cancer from developing in healthy people. These vaccines work by preventing viral infections that can lead to certain types of cancer. Examples include the Human Papillomavirus (HPV) vaccine and the Hepatitis B vaccine.
Treatment (therapeutic) vaccines
Treatment vaccines are a form of immunotherapy that treats an existing cancer by strengthening the body's natural defenses against the cancer. The Sipuleucel-T (Provenge) vaccine is an example of a treatment vaccine.
